The VALUE COLLECTION 525038PS is a zinc-plated steel K-Lock hex nut with an integrated external tooth lock washer, designed for metric fastening applications where vibration resistance is required. The K-Lock design combines a standard hex nut with a serrated external tooth lock washer in a single captive assembly, eliminating the need for a separate washer during installation. The M6x1.00 metric thread pitch and 10 mm width across flats make this nut compatible with standard M6 metric fastener systems. Zinc plating provides corrosion resistance in general indoor and light-duty industrial environments. Technicians and assemblers working with metal fabrication, HVAC equipment panels, electrical enclosures, and mechanical assemblies will find this a practical one-piece fastening solution.
This K-Lock nut is suited for residential and commercial applications where secure, vibration-resistant fastening is needed on M6 threaded studs or bolts. Typical installation scenarios include securing sheet metal panels, brackets, and component mounting plates in HVAC units, electrical enclosures, and general mechanical assemblies. The external tooth lock washer bites into the mating surface upon tightening, resisting loosening caused by vibration or thermal cycling. This nut is sold individually per package, with a minimum order quantity of 100 pieces.
Designed as a general-purpose metric replacement or new-installation hex nut for M6x1.00 threaded fastener applications in HVAC, electrical, and mechanical assembly environments.
Installation is performed by hand-threading onto any M6x1.00 threaded stud or bolt, then tightening with a standard 10 mm metric wrench or socket. Ensure the mating surface is clean and free of debris so the external tooth lock washer can seat properly and engage the surface. Power down or de-energize any equipment before servicing panels or enclosures where these nuts are being installed or replaced. Do not over-torque, as excessive force can flatten the lock washer teeth and reduce locking effectiveness.
