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.
