Professional Applications & Engineering Value

This 1/4"-20 UNC locknut delivers critical engineering solutions where vibration-induced loosening compromises assembly integrity. The top lock distorted thread technology creates permanent friction along the fastener engagement, eliminating the need for additional locking components while maintaining consistent clamp load. Manufactured from cadmium-plated steel, this fastener resists corrosion in industrial environments including outdoor equipment, machinery, and automotive applications. The external hex drive design ensures compatibility with standard tools while the coarse thread spacing enables rapid installation in high-volume production environments. This ASTM Grade C certified locknut provides engineers with a reliable, single-component locking solution that reduces maintenance frequency and improves overall system reliability.

Specification Summary & Compliance

This locknut features 1/4"-20 UNC coarse threads with Class 2B thread fit tolerance for precise engagement. The fastener complies with ASTM Grade C material and performance standards, ensuring consistent mechanical properties and load capacity. Dimensions include 7/16" width across flats and 7/32" height. The right-hand thread direction and standard hex nut profile provide industry-standard compatibility. The cadmium plating offers corrosion resistance while maintaining electrical conductivity where required.
