INSERTS - S-Type Captive Threaded Stud

Product Description

S-Type Captive Threaded Stud Inserts function like the Knurled Blind Threaded Inserts, but leave a threaded stud protruding from the panel after installation. Components can then be attached and secured by a mating nut. These studs can be used in place of clinch or weld studs, before or after finish. Optional head designs include a weathertight PVC foam sealed head, or a wedged head for more torque capabilities.

As these are installed, the knurled body expands 360° to fill the hole, creating exceptional torque strength and resistance to vibration. A backside flange is also formed, even in multiple thicknesses of materials without any need for adjustments. These inserts are to be used with Grade 5 or Metric 8.8/9.8 non thread-locking type nuts.

Most sizes are available in Standard, Sealed and Wedged head features. Sizes listed on this page are a representative sampling of materials and finishes. Please contact EFC International for sizes, materials or designs not shown.

Features & Benefits
  • Protruding Stud holds component parts until final assembly
  • Exceptional Torque Strength 360º hole fill
  • Quality Installation even in variable thickness material is assured with special tools available directly from EFC International
  • No Paint Masking - can be installed after painting
  • Corrosion Resistance - standard zinc/yellow dichromate finish (96 hrs. salt spray to white corrosion). Other finishes are available upon request.
  • Weathertight - Optional PVC Foam Seal under the head
  • Wedged Head increases torque capability, especially in soft or thin materials is ideal for electrical grounding applications.
For information on corresponding pneumatic or hydraulic tools available, please contact EFC International at 1-800-888-3326.

Hole Size: +.006 -.000in (+0.15 -0.00mm) (HD) - ±.010in (±0.25mm) (HH) - ±.003in (±0.08mm) (L) - ±.020in (±0.50mm)

*Note: Grip Range can be affected by parent material density and actual hole size. Trial Installations are recommended to determine optimum grip.
