The VALUE COLLECTION 31202 is a 5/16-18 UNC steel hex nut intended for general mechanical fastening applications. It features a right-hand thread direction and a zinc-plated finish that provides basic corrosion resistance in standard service environments. The nut measures 1/2 inch across the flats and 17/64 inch in height, conforming to standard hex nut geometry for use with 5/16-inch fasteners. This is a high-volume utility fastener suited for assembly, fabrication, maintenance, and repair work across HVAC, plumbing, electrical, and general mechanical trades.
This nut is appropriate for residential and commercial applications wherever a 5/16-18 UNC threaded connection is required. Common install scenarios include equipment mounting, bracket assembly, pipe hanger hardware, and general structural fastening. It is sold individually but carries a minimum order quantity of 200 pieces, making it suitable for stocking in shop inventory or field service kits where this thread size sees regular use.
Designed for use with any 5/16-18 UNC threaded bolt, stud, or threaded rod in standard inch-series fastener applications.
Installation is performed by hand-threading onto a mating 5/16-18 UNC fastener and tightening with a 1/2-inch wrench or socket. Ensure mating threads are clean and free of debris before installation. Do not over-torque, as this can strip threads or deform the nut. Follow applicable equipment manufacturer specifications or relevant code requirements for final torque values.
