Value Collection 32300 Heavy Hex Nut 1-8 Unc Steel

Product Description

The VALUE COLLECTION 32300 is a heavy hex nut threaded to the 1-8 UNC standard with a right-hand thread direction. Manufactured from steel with a zinc-plated finish, this nut provides a larger bearing surface and greater wrenching height than a standard hex nut, making it the correct choice for heavy structural bolting, anchor bolt applications, and high-load fastener assemblies. At 1-5/8 inches across the flats and 0.9844 inches in height, it meets the dimensional requirements for heavy hex fastener systems used across industrial and construction trades.

This heavy hex nut is suited for structural steel connections, machinery mounting, anchor rod assemblies, and general industrial fastening where a standard hex nut does not provide sufficient bearing area or clamping force. Ironworkers, millwrights, pipefitters, and maintenance technicians commonly specify heavy hex hardware for high-load or code-required connections. The zinc-plated finish offers a basic level of corrosion resistance for indoor and sheltered outdoor installations.

Key Features

• Heavy hex profile provides increased bearing surface versus standard hex nuts
• 1-8 UNC thread form for compatibility with coarse-thread fastener systems
• Right-hand thread direction — standard installation direction
• Steel construction for high tensile load capacity
• Zinc-plated finish for basic corrosion protection
• 1-5/8 inches across flats, 0.9844 inches high

Compatibility

Designed for use with 1-8 UNC coarse-thread bolts, studs, and anchor rods requiring a heavy hex nut seating profile.

Installation Notes

Installation is performed by hand-threading onto a compatible 1-8 UNC fastener followed by tightening with an appropriate open-end, box, or impact wrench sized for a 1-5/8-inch hex. Verify that the mating bolt or stud thread class and grade are compatible with the load requirements of the application before torquing. Consult applicable structural or mechanical codes for torque and inspection requirements. Do not use impact tools at excessive speed on zinc-plated hardware in applications where finish integrity affects corrosion resistance.
