The VALUE COLLECTION KEPI-100-100BX is a K-Lock hex nut with an integrated external tooth lock washer, manufactured from steel with a zinc plated finish. Designed for 10-24 UNC threaded fastener applications, this one-piece nut-and-washer assembly combines the clamping function of a standard hex nut with the vibration-resistant bite of an external tooth lock washer. The zinc plating provides a base level of corrosion resistance for general indoor and light-duty outdoor use. Each unit weighs approximately 0.0035 pounds. This style of fastener is commonly installed by electricians, HVAC technicians, plumbers, and general mechanical trades wherever a positive thread lock is needed without a separate washer component.
The KEPI-100-100BX suits a wide range of light-gauge panel, enclosure, and equipment assembly applications that use 10-24 UNC threaded fasteners. The external tooth lock washer seats against the mating surface as the nut is tightened, biting into the material to resist loosening from vibration or thermal cycling. The washer diameter measures 13/32 inches and the width across flats measures 3/8 inches, making this nut compatible with a standard 3/8-inch hex driver or wrench. It is sold in a minimum order quantity of 100 pieces per box, suited to production assembly, service van stocking, and maintenance operations.
Designed for use with 10-24 UNC machine screws and threaded fasteners in standard panel, enclosure, and mechanical assembly applications.
Install using a 3/8-inch hex wrench or socket driver. Ensure the mating surface is clean and free of debris so the external teeth can seat and bite properly. Do not over-torque, as excessive force can strip the 10-24 threads or flatten the lock washer teeth, reducing locking effectiveness. De-energize any electrical panel or equipment before installing or removing fasteners in live assemblies.
