The VALUE COLLECTION HFNFI20430-050BX is a 7/16-20 serrated flange nut manufactured from Grade 2 steel with a zinc-plated finish. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist vibration-induced loosening without requiring a separate lock washer. The flange diameter measures 0.937 inches, and the overall height reaches 0.395 inches. This nut is sold in a box of 50 and is installed by mechanical contractors, maintenance technicians, and assembly professionals working on general-purpose fastening applications.
Serrated flange nuts in the 7/16-20 fine-thread configuration are commonly used in applications where vibration resistance is required and flange-bearing load distribution is preferred over standard hex nuts. The fine-thread pitch provides improved torque control and greater resistance to loosening under dynamic loads. Typical installation scenarios include structural assemblies, equipment mounting, and mechanical sub-assemblies in both light industrial and commercial maintenance settings.
Designed for use with 7/16-20 UNF-threaded fastener assemblies requiring a serrated flange nut in inch-system hardware.
Installation is performed by hand-threading the nut onto a compatible 7/16-20 male-threaded fastener, then torquing to the assembly specification using an appropriate wrench. Minimum width across flats is 0.675 inches and maximum is 0.688 inches, so use a correctly sized 11/16-inch wrench or socket. Ensure mating surfaces are clean and free of debris before seating the serrated flange to allow the serrations to engage properly. Do not reuse serrated flange nuts in safety-critical joints once they have been fully torqued and removed.
