Embossed vs. Slotted Worm-Drive Hose Clamps – Perfect for the Marine Industry!
EFC offers in stock Swedish Style Worm Drive Clamps. These clamps have an embossed band versus the slotted band of the traditionally manufactured hose clamps.
The slotted band will extrude the hose through the slots when tightened on the hose. This cheese grater effect not only damages the hose material, it also hinders the clamp from smoothly riding over the hose when tightened. The interlocking of the hose with the band slots creates a reactive torque moment that needs to be overcome with a higher installation torque. In addition, the small contact surface between the screw thread and the band slots generates high friction, therefore even LESS torque is converted into band tension. The trapezoidal shape of the embossed band allows for more contact with the screw threads, therefore MORE torque is converted into band tension.
Embossed band worm-drive hose clamps have roll-formed band edges that minimize damage of the hose material as well as the risk of injury to the installer.
The housing of this worm gear clamp is manufactured from a tube in one piece that secures
high breaking torques and reliability. The solid band with a smooth inside as well as the rounded edges, protect the hose against damages and ensure a perfect sealing. Band width 9.7 and 11.7 mm.
Get a clamp that is far superior to slotted clamps at a competitive price! Call us about our REALLY BIG SALE on these clamps! Your business will gain financially and gain peace of mind avoiding warranty claims due to hose system failures.
In stock sizes on sale range from clamping range of 8-14mm (5/16” – 9/16”) up to 150-180mm (5 1/2:” 7”).
Show your customers a commitment to quality and purchase the best clamp on the market.
EFC International Will Help You Choose the Right Clamp!
Worm Gear: Inexpensive and lightly constructed clamp for general purpose automotive and industrial applications. Generally used in applications such as air and fuel lines. They work fine while you are ironing out details of your system. Hi-Torque is the strongest worm-gear clamp and features all stainless steel construction; an inner liner is also available. https://www.efc-intl.com/products/efc-clamps/worm-gear-clamps.htm
T-Bolt: Performance-engineered for long-term durability and a wide variety of applications. The standard hose clamp used on intake hoses throughout the industry. Very high holding power. A wider band provides for superior system stability. Thicker metal in the band means higher strength and longer life. The only disadvantage is a narrow range – you must have the correct size in order for it to work properly. Fully lined. Medium cost. https://www.efc-intl.com/products/efc-clamps/t-bolt-clamps.htm
Constant Torque: A breakthrough in clamping technology. A Belleville spring mechanism automatically increases or decreases the clamp diameter due to changes in operational or environmental temperatures to eliminate “cold flow” leaks. Widely used in air-to-air after cooler systems. Wide range and fully lined. Automotive, Heavy Duty and Industrial applications. Complex construction means higher cost. https://www.efc-intl.com/products/efc-clamps/constant-tension-clamps.htm
Spring-Loaded: A constant tension clamp with a spring designed for a variety of automotive, industrial, and marine applications. Maintains uniform and constant tension for fluctuation on hoses. Largely super-ceded by newer constant torque technologies but still widely used. There is a narrower range compared to constant-torque and less capability to handle rapid pressure spikes and slowly losing tension in the spring over time. Fix tension easily by adjusting the clamp periodically. Their ability to compensate for the expansion and contraction of hoses and fittings due to temperature is about the same as constant-torque. Most are floating-bridge type using a trunnion-style bridge, which keeps the clamp aligned during tightening and tightens more evenly around the entire diameter of the hose. Available with standard and heavy duty springs. Medium-high cost. https://www.efc-intl.com/products/efc-clamps/t-bolt-clamps.htm
V-Band: Provide fast, secure high-strength coupling to connect flanged joints. V-Band clamps enable industries to meet exact requirements in Aero-space, industrial, automotive, heavy duty and marine. Typical V-Band applications are turbocharger connections, Diaphragm pumps, ducting, air, and exhaust, pool/spa filters and pumps, food processing/dairy equipment.
Marine Grade: EFC has stock on clamps perfectly suited for the marine and irrigation industries with high-grade materials in 316 stainless to combat corrosion from saltwater. Features: 1-piece tubular housing (nonwelded) for maximum strength, smooth I.D. reduces hose damage and maximizes conversion of torque to clamping force, rolled edges protect hose from abrasion, and available in 10 mm and 12 mm bandwidths. https://www.efc-intl.com/products/efc-clamps/worm-gear-clamps/clamps-worm-gear-marine-embossed-german-multi-range-9-12mm-wide-all-316ss.htm
Still not sure which clamp to use, EFC’s clamp experts will help you get the right clamp for the job with a simple phone call!
“Lightweighting” has certainly been a buzz word the past few years for anything on wheels! In 2018 GM unwrapped the 2019 Chevy Silverado 1500. Through extensive use of mixed materials, the new truck weighs less than the outgoing model—up to 450 pounds less for some versions. “The weight savings comes from extensive use of mixed materials and advanced manufacturing processes throughout the next-gen truck,” says Tim Herrick, executive chief engineer of full-size trucks at GM. “This allowed us to use the right material for the application and optimize every component for mass, durability, safety and functionality to meet our customers’ needs.”
“I don’t know of any OEM that isn’t targeting at least one weight class reduction on new models that they’re developing. Over the next two decades, we expect to see incremental improvements in weight reduction on every new vehicle and every new component. This is a never-ending battle and every component is being challenged.” – Stated by Alan Taub who previously worked in R&D at Ford, GM and GE and now of Lightweight Innovations for Tomorrow (LIFT).
Fastening and assembly in lightweight materials creates many challenges. In steel, we can weld, pierce, clinch, bolt and more. In composite materials we must develop unique methods of fastening that do not require high forces and temperatures. The BBA blind rivet nut allows flexibility with unique strength and corrosion resistance in composites and metals. BCT® (Bulge Control Technology) allows the rivet nut to install quickly, clamp into material without any radial expansion in the hole, and control the collapse to ensure there is no damage to material.
Producing BCT® rivet nuts from aluminum for use in aluminum and magnesium, weight is reduced dramatically. In areas using advanced high strength steel, when welding is not currently advisable and self-piercing fasteners are not hard enough to join materials properly, the BBA Ultra Series Rivet nuts can reach Torque level adequate to break a Grade 12.9 bolt with torque. Using high strength steel materials, the cold forming process yields a very strong fastener, but allows proper installation with conventional rivet nut tools.
The BCT fastener has the same grip range capability of up to three standard rivet nuts. BCT rivet nuts can be placed near to the edge of the sheet without fear of inducing a crack in the sheet. Available in hexagon body for the ultimate in joint performance.
BCT can be installed in areas with limited rear side clearance. An M6 rivet nut needs only 8mm of rear side clearance prior to installation and only 5mm after installation –perfect for use in thinner versions of sandwich materials, avoiding the need for a through hole.
EFC will work with you to overcome challenges, find alternatives and develop processes to reduce weight.

Do You Need to Bundle Your Bungled Application?
EFC is a stocking master distributor for HellermannTyton – manufacturer of solutions that help customers manage wire, cable and components. EFC carries a wide range of products and will assist you in finding the perfect solution to fit your application. For bundling & securing products, electrical installation, identification, network connectivity, routing, protection and insulation check us out.
What are you trying to do – Bundle, Secure, Bundle & Secure or Separate Bundles? If you ask, what’s the difference? Here you go:
Bundle – wires, tubes, etc. together – NOT connecting a bundle to a surface. Do you have a heavy-duty application? Heavier than 120 lbs.
Secure – primarily mounts (you will need a secondary part for bundling). In addition, products that connect two parts like hoses.
Bundle & Secure – to an edge, to an existing hole, to a stud, or with something else like a screw, bolt or nail.
Separate Bundles – in some cases, they also mount to a surface. Do you want to separate bundles with a range of sizes or fixed size?
International Fastener Expo (IFE) 2018
Congratulations to Brian Rzepka of Valley Fastener Group, winner of EFC’s booth give-away, Xbox One! Thanks to everyone who stopped by the booth to register to win at IFE (International Fastener Expo).
A hot topic at the show and, of course, industry wide was what to expect in 2019 on U.S. Tariffs and Trade Policy. The new regulations have added more projects on desks for learning how to navigate through the lists, logistics, and strategize on how to manage price increases. Some networking within the industry and taking advantage of workshops, webinars or conferences will, I hope, ease the burden.
We will see everyone next year a little earlier in September at IFE.
GIE Expo 2018
EFC International will be exhibiting again at the GIE Expo (Green Industry & Equipment Expo) in Louisville October 17-19, Booth 10018 in the OEM Supplier Pavilion. This is the largest show for the industry and includes outdoor demonstration areas. Exhibitors at the show include Briggs & Stratton, The Toro Company, Caterpillar, Echo, John Deere Company, Kohler, Stihl, Kubota, Makita, and hundreds more.
Products highlighted in the EFC booth will include HellermanTyton’s Ratchet P clamp, an innovative wire bundling solution for heavy equipment manufacturers who want to reduce costs without compromising performance. It features an adjustable ratchet clamp mechanism; it comes in four sizes, four mounting configurations and two metal base materials. Cut the time required for wire harness and cable installation!

Also on display, StockCap, handgrips, vinyl, rubber and plastic plugs and caps for product protection. Whether you need a standard tube end cap or a custom part designed to your specifications, EFC will work with you to find the solution that works.
ARaymond designs and manufactures fasteners for the green industry. Clips, supports and hooks enable growers to simplify, maximize yields and minimize labor costs. ARaymond offers a range of biodegradable (who knew?!) fastening solutions in addition to its plastics range.
Heyco introduced this year UL recognized thermoplastic rubber grommets for mounting hole diameter ranges of .375” to 2.000”. Convert raw-edged holes to smooth, neat, insulated holes. You have the ability to insulate and mechanically protect cable, tubing, hose, rope, rods, and shafts. Diameters fit panel thicknesses from .03” to .13”. The temperature range is -40ºF to 221ºF.
Sherex introduced a line of M10 full hex structural rivet nuts perfect for high performance, high strength fastening solutions and needed for this industry. The OEM they worked with was having challenges with weld nuts in the frame assembly. They had to mask and unmask the weld nut threads before and after the powder coast process. These extra steps caused delays in the manufacturing process. Using the new M10 rivet nuts with the Sherex FLEX-18 installation tool, reduced production time by 20 minutes per frame assembly. Talk to us at the show about more cost saving solutions.
Recently introduced to the show are UTVs (Utility Task Vehicles). As a premier provider to the automotive and truck industry, EFC is a natural solution and go-to source for fastening UTVs – including wire routing, clamps, panel fasteners, handles, knobs, specialty screws, and connectors. If you’re wondering what the difference is between a UTV and an ATV as I was, here you go — ATVs are all terrain vehicles and smaller than a UTV and they’re recreational. UTVs also called side by sides are off-road vehicles that can seat 2-4 and designed for rougher terrain, hauling – a.k.a. work!
And one more exciting give-away – as if the Oetiker Irrigation Clamp Kits weren’t enough, we have a remote control excavator to give away. It’s the envy of the guys in the office and now on their Christmas list.
See you in Louisville at GIE Expo!
Clamps, Clamps, and More Clamps!
The most popular types of clamps for hose/tube, wire routing and affixing.
Regardless of your application – hose/tube, wire routing or affixing – there are numerous types of clamps to fit your application solution. Many of these types of clamps appear in EFC’s on-line engineering guide (Encyclopedia of Engineered Components), specifically in our clamp “book” found here. The most popular clamp types include constant tension, crimp style, cushion/routing, worm-gear, T-bolt and V-band.
Constant Tension clamps come in various styles (CTB band, screw-drive w/ spring element or belleville washers, or with traditional springs). Constant Tension clamps enable spring-action to ensure a “constant tension” to prevent hose leaks due to pressure changes or thermocycling.
Crimp Style clamps include ear clamps that require an “ear” to be pinched to install. Advantages include ease of installation, tamper proof design, concentrated seal compression and are ideal for hard-to-seal applications like molded plastics and automotive applications.
Cushion and Routing clamps include metal “P clamps”, with or without a cushion, for affixing hose, tubes, pipes, cables or wire bundles. The clamps are affixed typically by using a bolt. Other types of routing clamps include both metal and plastic clamps of varying styles and designs for affixing or routing cables and wire bundles.
Worm-gear clamps are extremely popular as they can be removed or adjusted after installation and typically just require a screw-driver to install them. They come in varying styles for numerous application solutions. Worm-gear clamps can accommodate a range of diameters, which is a major benefit.
T-Bolt clamps are often used for heavy duty / high strength applications.
V-band clamps provide a secure connection and positive sealing for “coupling” together flanged joints. Available for high torque and with quick latch options. These clamps are often used in heavy-duty diesel engine exhaust and turbochargers.
