The VALUE COLLECTION SNFI2043-050BX is a slotted hex lock nut designed to resist loosening under vibration and dynamic loads. Manufactured from Grade 2 steel with a bright, uncoated finish, this nut conforms to the UNF (Unified National Fine) thread standard at a 7/16-20 thread size with right-hand thread direction. It measures 3/8 inches high with a width across flats of 11/16 inches. The slotted design accepts a cotter pin or safety wire for positive locking, making it suitable for mechanical assemblies where fastener retention is critical. Plumbers, HVAC techs, electricians, and general mechanical tradespeople use this type of nut across a wide range of structural and equipment installations.
This slotted hex lock nut is suited for use in residential and light commercial mechanical assemblies where UNF-threaded fasteners are required. Typical applications include equipment mounting, bracket hardware, plumbing fixture connections, and general-purpose structural fastening where vibration resistance is needed. The 7/16-20 UNF thread specification is common in machinery, HVAC equipment frames, and plumbing support hardware. This product is sold in a minimum order quantity of 5 units.
Designed as a standard UNF slotted hex lock nut for use with 7/16-20 right-hand threaded bolts and studs in general mechanical, HVAC, plumbing, and light structural applications.
Installation requires a standard 11/16-inch open-end or combination wrench. After torquing the nut to the assembly specification, align the slots with the cotter pin hole in the mating fastener and insert an appropriately sized cotter pin or safety wire to lock the nut in place. Always de-energize or shut off any connected equipment before servicing fastened assemblies. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
