Hi-Stress Fastener

Hi-Stress Fasteners are made of heavy gauge material and are designed for use on fine-thread-series screws. Their modified Speed Nut impression provides vibration resistance and constant torque on the screw threads, assuring a locked-on grip at any point on the screw-even after many removals. Types are available for either welding or riveting and screw sizes range from 8-32 to 1/4-20.

The rugged Hi-Stress Fastener is made of heavy gauge material and is designed for use on fire-thread-series screws. The modified Speed Nut impression provides vibration resistance and constant torque on the screw thread assuring a lock-on grip at any point on the screw even after many removals. It is light in weight and has a lower installation torque than most multiple-threaded, prevailing torque fasteners. Thread galling is eliminated and more rapid insertion of bolts and screws is possible.

Types are available for either welding or riveting and screw sizes range from 8-32 to ¼-20.

How to apply Hi-Stress Fasteners

Before final assembly, Hi-Stress-Type Fasteners are spot-welded or riveted in screw-receiving position. Mating panels are aligned and screw driven. Resiliency in the modified Speed Nut impression allows slight misalignment and absorbs tolerance build-up where several fasteners are required on a single unit.
