Palnut® Regular Type Lock Nuts

Palnut® Lock Nuts incorporate a design principle that has stood the test of over 60 years. These nuts may be used alone for load-carrying in lightduty assemblies or they may be used on top of ordinary nuts to assure tightness of high-stress assemblies. They offer impressive savings over alternative fasteners in initial cost, assembly time, weight and space. They are removable, reusable, and self-cleaning. They are unaffected by temperatures up to 400 degrees.
Torque and tension values are not shown for some of the large size parts above. These sizes are primarily used as lock nuts on top of ordinary nuts, or as load carrying nuts on applications where joint loading is mainly in shear. In both situations the tensile (clamping) strength of the Palnut® Lock Nut exceeds most conservative design requirements, and tightening is usually done manually.
