Value Collection HMSNI20310-100BX Hex Nut 5/16-18 Grade 2

Product Description

The VALUE COLLECTION HMSNI20310-100BX is a 5/16-18 UNC hex nut manufactured from Grade 2 steel with a clear zinc finish. It features a right-hand thread and measures 9/16 inches across the flats and 7/32 inches in height. This nut is a standard fastener used across mechanical, structural, and trade applications wherever a 5/16-18 threaded bolt or stud requires secure fastening. Each package contains 100 pieces, making it suitable for bulk fastener inventory in shop, field, or job-site use. Installation requires only a standard 9/16-inch wrench or socket.

This hex nut fits a wide range of general-purpose assembly applications including HVAC equipment mounting, plumbing fixture installation, electrical panel work, and structural framing. The clear zinc coating provides basic corrosion resistance for indoor and light-duty outdoor environments. The Grade 2 designation indicates standard low-carbon steel construction, appropriate for non-critical fastening tasks. The 100-piece minimum order quantity makes this well-suited for stocking fastener bins or completing multi-unit service jobs requiring consistent hardware.
