Value Collection 39602 Hex Nut 5/16-18 Grade 8 Steel

Product Description

The VALUE COLLECTION 39602 is a 5/16-18 hex nut machined from Grade 8 steel and finished with a zinc yellow dichromate coating for corrosion resistance. It features a right-hand thread cut to UNC (Unified National Coarse) standards, making it a standard fastener for structural and mechanical assembly applications. The nut measures 0.5 inches across the flats and 17/64 inch in height, with a unit weight of 0.011 pounds. Grade 8 steel provides high tensile strength, suitable for demanding bolted connections in equipment, machinery, and general trade construction work. Installation requires a standard wrench or socket sized to fit a 1/2-inch across-flats hex profile.

This hex nut is used in a wide range of residential and commercial trade applications including HVAC equipment assembly, plumbing bracket work, electrical panel mounting, and structural fastening tasks. It is appropriate wherever a high-strength UNC-threaded 5/16-18 nut is required. The zinc yellow dichromate finish provides added protection in mildly corrosive environments such as mechanical rooms and equipment pads. Sold individually, with a minimum order quantity of 100 pieces, making it suited for contractors stocking hardware for recurring jobs.

Compatibility

Designed as an OEM-style replacement or standard fastener for any application requiring a 5/16-18 UNC Grade 8 steel hex nut with a zinc yellow dichromate finish.

Installation Notes

Install and tighten using a standard wrench or socket sized for a 1/2-inch hex profile. Follow applicable torque specifications from the equipment manufacturer or relevant code, such as ASME or NEC guidelines where fastener grade requirements are specified. Do not mix Grade 8 nuts with lower-grade bolts or studs, as mismatched hardware grades can compromise joint integrity. Inspect threads for damage before installation and ensure mating fastener threads are clean and free of debris.
