Value Collection B52001645 Hex Nut 1-3/4-5 Grade 8

Product Description

The VALUE COLLECTION B52001645 is a heavy-duty hex nut designed for high-load fastening applications in industrial, mechanical, and structural assemblies. It is manufactured from Grade 8 steel with no finish coating applied, making it suitable for environments where a secondary treatment will be added by the installer or where bare steel is acceptable. The nut features a 1-3/4-5 UNC (Unified National Coarse) thread size with right-hand thread direction. The width across flats measures 2.75 inches and the height measures 1.5 inches. At 0.4 pounds, this is a substantial fastener built to handle high-strength bolting requirements.

This hex nut is used in heavy mechanical assemblies, construction equipment, agricultural machinery, and industrial fabrication where Grade 8 strength ratings are specified. The coarse UNC thread pattern makes it faster to assemble and more resistant to cross-threading in field conditions. It is typically installed by millwrights, ironworkers, mechanical contractors, and maintenance technicians working on large-diameter fastener applications. The uncoated finish means the installer or fabricator takes responsibility for any corrosion protection requirements based on the service environment.

Key Features

• Grade 8 steel construction rated for high-tensile, high-load fastening
• 1-3/4-5 UNC thread size with right-hand thread direction
• Width across flats of 2.75 inches for use with standard heavy hex tooling
• Height of 1.5 inches providing full thread engagement depth
• Uncoated finish allows for field-applied corrosion treatments as required
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed for use with 1-3/4-5 UNC Grade 8 bolts and threaded rod in heavy industrial and structural fastening applications.

Installation Notes

Installation should be performed by qualified mechanical or structural trades familiar with large-diameter fastener torquing procedures. Always verify that the mating bolt or threaded rod matches the 1-3/4-5 UNC thread specification before assembly. Torque values must be sourced from the applicable engineering specification or fastener manufacturer data — do not estimate on high-load connections. The uncoated surface should be evaluated for corrosion protection needs prior to installation in exposed or wet environments.
