Value Collection HNI8150-010B Hex Nut 1-1/2-6 Grade 8

Product Description

The VALUE COLLECTION HNI8150-010B is a heavy-duty hex nut threaded to a 1-1/2-6 UNC specification in Grade 8 steel with a bright, uncoated finish. Grade 8 steel delivers high tensile strength suited to demanding structural, mechanical, and industrial fastening applications. The nut measures 2.25 inches across the flats and 1.28 inches in height, with a right-hand thread direction. Machinists, millwrights, maintenance technicians, and mechanical contractors use this fastener when joint integrity under high load or vibration is a priority.

This hex nut is appropriate for use in heavy equipment assembly, structural steel connections, industrial machinery, and general mechanical maintenance where a coarse-thread Grade 8 fastener is specified. The 1-1/2-6 UNC thread pitch is a standard coarse series, making it compatible with matching Grade 8 bolts and threaded rod stock of the same size and thread class. Sold individually per unit; minimum order quantity is 10 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• 1-1/2-6 UNC coarse thread, right-hand direction
• 2.25 inches across flats for standard heavy hex wrench engagement
• Bright uncoated finish — suitable for use where plating or coating would affect thread tolerance
• Meets standard UNC thread specification; does not meet military specifications

Compatibility

Designed for use with 1-1/2-6 UNC Grade 8 bolts and threaded rod in standard coarse-thread heavy fastening applications.

Installation Notes

Installation is performed by mechanical and maintenance trades using standard heavy hex wrenches or impact tooling sized for a 2.25-inch across-flats nut. De-energize and lock out any equipment before servicing fastened assemblies per applicable OSHA lockout-tagout procedures. Thread engagement should be verified for full nut height contact; do not mix thread classes or grades within a joint assembly. Consult applicable structural or mechanical codes for torque class requirements on the specific joint being fastened.
