Value Collection HHXN025CG-PK100 Hex Nut 5/16-18 Grade 2

Product Description

The VALUE COLLECTION HHXN025CG-PK100 is a 5/16-18 UNC hex nut made from Grade 2 steel with a hot-dipped galvanized finish. Sold in packs of 100, this nut is a standard fastener used to secure threaded fastener assemblies across a wide range of mechanical and structural applications. The 5/16-18 thread size follows Unified National Coarse (UNC) standards with a right-hand thread direction. The hot-dipped galvanized coating provides corrosion resistance in exposed or outdoor environments. Width across flats measures 9/16 inches, and the height is 19/64 inches. Licensed tradespeople and contractors use these nuts in everyday assembly, maintenance, and repair work.

These hex nuts are suited for general-purpose fastening in residential and light commercial construction, mechanical equipment assembly, HVAC equipment mounting, plumbing support structures, and electrical enclosure work. The Grade 2 steel designation indicates a standard-strength carbon steel fastener appropriate for non-critical structural connections and general hardware applications. The galvanized finish makes them a practical choice for outdoor installations, exposed brackets, conduit support, and other assemblies where moisture exposure is a concern.

Installation Notes

Installation does not require licensed trade credentials, but should follow applicable mechanical or structural codes for the assembly type. Use a 9/16-inch wrench or socket to drive the nut. Do not overtighten — follow the torque specifications published by the equipment or structure manufacturer for 5/16-18 Grade 2 fasteners. Inspect galvanized coating for damage before installation in corrosive environments; compromised coating reduces service life.
