Value Collection 99782 Hex Nut 3/8-16 Grade 8 Steel

Product Description

The VALUE COLLECTION 99782 is a 3/8-16 hex nut machined from Grade 8 steel with a black oxide finish. Grade 8 steel provides high tensile strength suited for heavy-duty fastening applications where standard hardware-grade nuts would be insufficient. The black oxide finish offers mild corrosion resistance and a consistent matte appearance. This nut uses a right-hand thread with a UNC thread standard, measures 9/16 inches across the flats, and stands 21/64 inches tall. It weighs 0.016 pounds per unit. Tradespeople, fabricators, and maintenance technicians reach for Grade 8 fasteners when joint integrity under load or vibration is a priority.

This hex nut is suited for structural bolting, heavy equipment assembly, industrial machinery maintenance, and general mechanical fastening where UNC 3/8-16 threading is specified. The black oxide finish makes it a common choice in applications where a non-reflective, dark fastener finish is required alongside high-strength performance. It is compatible with any standard 3/8-16 UNC threaded bolt or stud used in fabrication, HVAC equipment frames, electrical panel mounting, and similar trade installations.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• Black oxide finish provides mild corrosion resistance and low-reflectance appearance
• Right-hand UNC 3/8-16 thread for broad compatibility with standard fasteners
• 9/16 inches across the flats for use with standard 9/16-inch wrenches and sockets
• 21/64 inches height — standard heavy hex profile for the thread size

Compatibility

Designed for use with any 3/8-16 UNC right-hand threaded bolt or stud. Suitable for structural, mechanical, and equipment-mounting applications across HVAC, electrical, plumbing, and general fabrication trades.

Installation Notes

Installation is performed by hand-threading the nut onto the mating bolt or stud, then tightening with a 9/16-inch wrench or socket. Always ensure the mating bolt is also Grade 8 or equivalent to maintain joint integrity. Follow applicable torque specifications from the equipment manufacturer or relevant standards for the assembly. Minimum order quantity for this item is 100 units.
