Value Collection HNFI8150-005BX Hex Nut Grade 8 Unf

Product Description

The VALUE COLLECTION HNFI8150-005BX is a Grade 8 steel hex nut threaded to a 1-1/2-12 UNF specification with a right-hand thread direction. Finished bright and uncoated, it measures 2.25 inches across the flats and 1-9/32 inches in height. Grade 8 designates a high-strength fastener suitable for heavy-duty bolted assemblies where joint integrity under significant load is critical. This nut is used by mechanical contractors, millwrights, equipment assemblers, and maintenance technicians working on structural, industrial, or heavy mechanical applications.

This hex nut is appropriate for high-load bolted connections in industrial machinery, structural steel assemblies, agricultural equipment, and heavy-duty vehicle or trailer fabrication. The UNF thread form provides finer thread pitch than UNC, offering increased thread engagement and resistance to loosening in vibration-prone applications. The uncoated bright finish suits applications where post-installation coating or plating will be applied, or where a bare steel surface is otherwise acceptable.

Key Features

• Grade 8 steel construction for high tensile and proof load capacity
• 1-1/2-12 UNF right-hand thread for fine-pitch engagement
• 2.25 inches across flats for standard wrench sizing
• 1-9/32 inch height for full thread engagement depth
• Bright uncoated finish compatible with field coating or bare-steel use
• Does not meet military specifications — intended for commercial and industrial use

Compatibility

Designed as a standard UNF hex nut for use with Grade 8 or equivalent 1-1/2-12 threaded bolts and studs in commercial and industrial bolted assemblies.

Installation Notes

Installation is performed by licensed mechanics, millwrights, or maintenance technicians using appropriately sized hand or impact wrenches. Always confirm thread specification and grade match between the nut and mating fastener before assembly. Torque to the value specified by the equipment manufacturer or applicable engineering standard for the joint design. Inspect threads for damage or contamination before installation to ensure full load-bearing engagement.
