Value Collection 31217 5/8-18 Unf Hex Nut Steel Zinc-plated

Product Description

The VALUE COLLECTION 31217 is a 5/8-18 UNF hex nut machined from steel and finished with a zinc-plated coating for corrosion resistance. It features a right-hand thread pattern conforming to the Unified National Fine (UNF) standard, making it suitable for high-vibration and close-tolerance fastening applications. The nut measures 15/16 inches across the flats and 35/64 inches in height. It is a general-purpose fastener used by electricians, plumbers, HVAC technicians, and mechanical contractors for equipment assembly, panel mounting, and structural connections where a fine-thread hex nut is specified.

This nut is well suited for residential and light commercial trade applications where UNF threading is required for precise torque and tensioned connections. Fine-thread fasteners like this one are commonly used in equipment brackets, conduit fittings, pump assemblies, and mechanical linkages. The zinc-plated finish provides a baseline level of corrosion protection appropriate for indoor and protected outdoor installations. This SKU is sold in a package quantity of one unit with a minimum order quantity of 50 units.
