Value Collection HNI2031G-100BX Hex Nut 5/16-18 Galvanized

Product Description

The VALUE COLLECTION HNI2031G-100BX is a 5/16-18 UNC hex nut manufactured from Grade A steel with a hot-dipped galvanized finish. Hot-dipped galvanizing deposits a thick zinc coating that resists corrosion in outdoor, wet, and high-humidity environments, making this nut suitable for structural fastening, utility hardware, and general mechanical assemblies. The right-hand thread pattern conforms to standard UNC specifications. At 0.5 inches across flats and 17/64 inches in height, this nut is sized to accept a standard 1/2-inch wrench. This box contains 100 pieces. Mechanical contractors, plumbers, electricians, and general tradespeople use this fastener wherever a standard 5/16-18 nut is required.

This hex nut is used across residential and commercial construction, HVAC equipment mounting, conduit support hardware, plumbing fixture attachment, and general mechanical assembly. The galvanized finish makes it appropriate for outdoor fastening, rooftop equipment installation, and exposed structural connections where bare steel fasteners would corrode prematurely. The 100-piece box packaging suits job-site use and service van stock.
