Value Collection MP39155 Hex Cap Screw 5/8-11 Grade 8 10pk

Product Description

The VALUE COLLECTION MP39155 is a 5/8-11 hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. It measures 3.5 inches under the head and features partial threading along the shank. Grade 8 steel provides high tensile strength, making this fastener suitable for demanding structural and mechanical assemblies. The zinc yellow dichromate coating delivers corrosion resistance while meeting finish standards common in industrial and OEM applications. This screw is sold in a package of 10 and conforms to ASME B18.2.1 dimensional standards. It is installed by machinists, millwrights, maintenance technicians, and general tradespeople working with bolted assemblies that require a high-strength inch-series fastener.

This cap screw is used across a broad range of industrial, mechanical, and trade applications. Typical uses include structural steel connections, equipment frames, HVAC unit assembly, mechanical supports, and heavy-duty bolted joints where Grade 8 tensile ratings are specified. The 5/8-11 UNC thread designation is a standard coarse-thread series widely used in North American equipment manufacturing and field maintenance.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 5/8-inch hex head. De-energize and lock out any equipment before replacing fasteners in live assemblies. Torque to the specification listed in the equipment manufacturer's service documentation for Grade 8 hardware at this diameter. Inspect threads and mating nuts for damage before installation to ensure full thread engagement.
