Value Collection HNI8137-010BX Hex Nut 1-3/8-6 Grade 8

Product Description

The VALUE COLLECTION HNI8137-010BX is a Grade 8 steel hex nut with a 1-3/8-6 UNC thread size and a bright, uncoated finish. It features a right-hand thread direction and measures 2.0625 inches (2-1/16 inches) across the flats with a height of approximately 1-11/64 inches. Grade 8 steel construction provides high tensile strength suited for heavy-duty bolted connections. This nut is a standard fastener used by mechanics, millwrights, and general contractors in structural, machinery, and equipment assembly applications where a high-strength, coarse-thread fastener is required.

This hex nut is appropriate for use in industrial, commercial, and heavy equipment applications. It is designed for use with 1-3/8-6 UNC Grade 8 bolts or threaded rod in structural assemblies, heavy machinery mounting, and similar high-load fastening scenarios. The uncoated bright finish is suitable for interior and dry-environment applications or where a secondary coating will be applied after assembly.

Key Features

Compatibility

Designed for use with 1-3/8-6 UNC Grade 8 bolts and threaded rod in heavy-duty structural and mechanical fastening applications.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a 2-1/16 inch wrench or socket. Always verify that the mating bolt or threaded rod matches the 1-3/8-6 UNC thread specification and is also Grade 8 or equivalent to maintain joint integrity. Torque to values specified by the applicable engineering standard or equipment manufacturer for the joint being assembled. Inspect threads for damage or contamination before installation.
