Professional Applications & Engineering Value

This 10-24 zinc-plated steel locknut with external-tooth lock washer addresses critical vibration-induced loosening challenges in heavy machinery, automotive assemblies, and industrial equipment. The UNC coarse thread configuration enables rapid installation while resisting debris accumulation in demanding environments. The integrated steel lock washer with 0.406" OD creates positive mechanical locking by embedding its teeth into the contact surface, eliminating the need for secondary locking components. The zinc-plated finish provides sacrificial corrosion protection, making these industrial locknuts suitable for applications exposed to moisture, chemicals, or outdoor conditions where fastener integrity is paramount for operational safety and reduced maintenance intervals.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit for consistent engagement and reliable performance. Features UNC coarse threads (10-24) with right-hand direction and standard hex profile (3/8" width, 5/32" height). The external-tooth lock washer (0.406" OD) is integral to the locking mechanism. Complies with relevant industrial fastener specifications and RoHS/REACH environmental standards for material composition and surface treatment.
