Tinnerman® U-Type High Torque Fasteners


Hi-Torque U-Type Fasteners

High-Torque Fasteners. Equally at home on metal or plastic, these unique Tinnerman fasteners bring extra strength, reliability and economy wherever vibration, impact, or migration prevail.

They accept power driven screws readily, discourage cross-threading, won't clog with paint or freeze to screw threads. They are self-retaining over a wide range of panel thicknesses, yet permit trouble-free removal. Unusually high clamp loads are attainable. Prevailing torque is inherent in the design.

The Dimensions of the parts listed are envelope dimensions only. For complete design information, please request a blueprint from your Tinnerman Palnut representative or the Tinnerman Palnut Engineering Department.
