Value Collection 31233 K-lock Hex Nut 10-32 Zinc Steel

Product Description

The VALUE COLLECTION 31233 is a steel K-Lock hex nut with an integrated external tooth lock washer, designed for secure fastening in applications where vibration resistance is required. The external tooth design bites into the mating surface under torque, creating a mechanical lock that resists loosening. Finished in zinc plating for basic corrosion protection, this fastener is threaded to a 10-32 UNF specification. The washer diameter measures 13/32 inches and the width across flats is 3/8 inches. These nuts are handled and sold by trade professionals for general mechanical assembly work.

This K-Lock nut is suited for light mechanical and electrical enclosure assembly, panel mounting, and general-purpose fastening where a combined nut-and-lock-washer profile saves installation steps. The 10-32 UNF thread is common in electrical cabinets, control panels, and light structural assemblies. The integrated external tooth lock washer eliminates the need for a separate lock washer, reducing parts count and speeding up assembly on production or service work.

Key Features

• External tooth lock washer integrated into nut base for single-piece installation
• 10-32 UNF thread for compatibility with standard unified fine-thread fastener systems
• Zinc plating provides corrosion resistance for indoor and light-duty environments
• Width across flats of 3/8 inches fits standard hex drivers and wrenches
• Washer diameter of 13/32 inches provides positive bearing surface contact

Compatibility

Designed as a standard 10-32 UNF K-Lock hex nut suitable for general mechanical assembly applications requiring an integrated external tooth lock washer on a zinc-plated steel fastener.

Installation Notes

Installation is performed by hand-threading onto a 10-32 UNF male fastener, then torquing with a 3/8-inch hex wrench or socket. Ensure mating surfaces are clean and free of coatings that would prevent the external teeth from seating properly. De-energize and lock out any electrical panels or equipment before installing fasteners in live enclosures. Minimum order quantity is 100 pieces per order.
