The VALUE COLLECTION R52001637 is a 12-24 UNC K-Lock hex nut with an integrated external tooth lock washer, manufactured from steel with a zinc plated finish. This fastener combines a standard hex nut and a serrated external tooth lock washer into a single unit, providing vibration-resistant clamping without the need for a separate washer. The external teeth bite into the mating surface as the nut is tightened, resisting loosening under dynamic loads. At 0.0058 pounds per piece, it is well suited for light-duty electrical panel, enclosure, and equipment assembly applications where reliable thread retention is required.
This K-Lock nut is used in residential and commercial electrical, HVAC, and general mechanical assembly work where a compact, one-piece locking fastener is preferred. Typical install scenarios include securing components inside electrical enclosures, control panels, sheet metal assemblies, and HVAC equipment cabinets. The 12-24 UNC thread size is common in light-gauge metal applications. The zinc plated finish provides basic corrosion resistance for indoor and protected environments. Installation is handled by electricians, HVAC technicians, and general assembly trades.
Designed as a standard 12-24 UNC K-Lock replacement or assembly fastener for use in electrical enclosures, HVAC equipment panels, and general sheet metal assemblies requiring a one-piece hex nut and external tooth lock washer combination.
Installation is performed with a standard 7/16 inch hex wrench or socket. Ensure mating threads are clean and free of debris before installation. Apply consistent torque to allow the external teeth to seat properly against the mating surface without stripping the 12-24 threads. Power down and de-energize any electrical equipment before installing or removing fasteners inside live panels or enclosures.
