Value Collection MP39601 Hex Nut 1/4-20 Grade 8

Product Description

The VALUE COLLECTION MP39601 is a 1/4-20 UNC hex nut manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is among the highest-strength classifications for inch-series fasteners, making this nut appropriate for high-load structural and mechanical assemblies where fastener integrity is critical. The zinc yellow dichromate coating provides a base level of corrosion resistance and is visually identifiable by its gold-toned appearance. The nut measures 7/16 inches across the flats and 7/32 inches in height, with a right-hand thread direction conforming to UNC standards. Licensed trades and mechanical contractors will recognize this as a standard heavy-hex-style fastener suited to demanding service conditions.

This hex nut is used in a wide range of commercial, industrial, and trade applications where a 1/4-20 UNC thread pattern is required and higher clamping strength is a priority over standard Grade 2 or Grade 5 hardware. Typical installation scenarios include equipment mounting, HVAC structural brackets, electrical panel framing, mechanical supports, and general fabrication work. The yellow dichromate finish also makes these nuts easy to identify in multi-grade fastener inventories, reducing the risk of incorrect substitution on the job site.

Key Features

• Grade 8 steel construction delivers high tensile and proof load strength for demanding fastening applications
• Zinc yellow dichromate finish provides corrosion resistance and visual grade identification
• 1/4-20 UNC right-hand thread conforms to Unified National Coarse thread standards
• 7/16-inch width across flats fits standard SAE wrenches and sockets
• 7/32-inch height suits low-profile and standard fastening configurations
• Minimum order quantity of 50 units supports job-site and shop stocking needs

Compatibility

Designed for use with any 1/4-20 UNC threaded fastener, bolt, or stud requiring a Grade 8 hex nut. Suitable for use across HVAC, plumbing, electrical, and general mechanical assembly applications that specify UNC thread form and Grade 8 hardware.

Installation Notes

Installation is performed by hand and completed with a standard 7/16-inch wrench or socket driver. Always verify that the mating bolt or stud is also rated Grade 8 or equivalent to maintain the integrity of the fastened joint — mixing grades undermines the rated load capacity of the assembly. De-energize or isolate any equipment before fastener replacement or installation in live systems. Follow applicable mechanical and structural codes for proper torque procedures based on joint type and application.
