Value Collection KEPFI-100-050B Hex Nut Lock Washer 10-32

Product Description

The VALUE COLLECTION KEPFI-100-050B is a steel hex nut paired with an external tooth lock washer, sold in a 50-piece minimum order quantity. The external tooth configuration bites into the mating surface and the underside of the nut, resisting rotational loosening under vibration and dynamic loads. The zinc finish provides a base level of corrosion resistance suitable for indoor and general light-duty applications. These fasteners are threaded to the 10-32 UNC standard and carry an A2 material grade designation. Licensed electricians, HVAC technicians, plumbers, and general mechanical contractors reach for this combination fastener when panel work, equipment mounting, or enclosure assembly calls for a compact, reliable threaded connection.

This nut and lock washer combination is appropriate for light-gauge steel assemblies, electrical enclosures, control panels, HVAC equipment cabinets, and similar applications where a 10-32 unified coarse thread is specified. The external tooth lock washer is particularly common in electrical panel and ground bonding applications where maintaining a secure mechanical and electrical connection is critical. The zinc finish is compatible with most indoor environments and protected outdoor enclosures.

Key Features

• External tooth lock washer integrated for vibration-resistant fastening
• 10-32 UNC thread standard for broad compatibility with standard machine screws
• Steel construction with A2 material grade for reliable mechanical performance
• Zinc finish for general corrosion resistance in light-duty environments
• Sold in 50-piece quantity for efficient stocking and service work

Compatibility

Designed for use with 10-32 UNC machine screws in standard hex nut applications across electrical, HVAC, and mechanical assembly work.

Installation Notes

Installation is performed by hand-starting the nut onto a 10-32 UNC threaded fastener, then tightening with a standard hex wrench or nut driver. De-energize all electrical circuits before working inside panels or enclosures, in accordance with NFPA 70 lockout requirements. Ensure mating surfaces are clean and free of paint or debris so the external teeth seat properly against bare metal for secure locking action. Do not reuse lock washers that have been fully compressed, as the locking effectiveness is reduced after initial torque.
