Value Collection HHNI22000-005BX Hex Nut 2-4-1/2 Unc

Product Description

The VALUE COLLECTION HHNI22000-005BX is a heavy-duty hex nut designed for large-diameter fastening applications in structural, mechanical, and industrial assemblies. Built from Grade 2 steel with a clear zinc finish, this nut provides corrosion resistance suitable for general-purpose indoor and sheltered outdoor use. It carries a 2-4-1/2 thread size per UNC standards and measures 3.125 inches across the flats with a height of 1-31/32 inches. Right-hand thread direction follows standard convention. Weighing 1 pound, this is a substantial fastener intended for high-load connections where a large-diameter threaded interface is required. Licensed tradespeople, millwrights, and heavy equipment technicians are the primary installers.

This hex nut is suited for structural steel connections, heavy machinery assembly, industrial framework, and similar large-format fastening tasks. Its UNC thread form is compatible with standard inch-series threaded rod, bolts, and studs of the same diameter and pitch. The clear zinc coating provides a base level of corrosion protection appropriate for controlled environments and general shop or field use. It is packaged individually and sold as a single unit.

Installation Notes

Installation should be performed by qualified tradespeople or mechanical technicians familiar with large-diameter fastener assemblies. Ensure mating fastener thread size, pitch, and standard match before assembly. Use appropriate torque specifications from the governing engineering specification or relevant code, such as AISC or applicable structural standards. Inspect threads for damage or contamination before assembly to avoid cross-threading or galling on this large-format fastener.
