Value Collection MP39160 Hex Cap Screw 5/8-11 X 5-1/2 in Grade 8

Product Description

The VALUE COLLECTION MP39160 is a 5/8-11 hex head cap screw measuring 5-1/2 inches in length under the head, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is a high-strength classification suitable for demanding fastening applications where tensile and proof load requirements exceed those of lower grades. The partially threaded shank provides a grip zone that resists joint slippage under heavy load. This fastener conforms to ASME B18.2.1 dimensional standards and uses a UNC thread form. Machinists, millwrights, equipment assemblers, and maintenance technicians typically specify this screw for structural and mechanical assemblies requiring verified strength grades.

This screw is suited for industrial, commercial, and heavy-equipment applications where a UNC 5/8-11 thread pattern and high-strength Grade 8 material are required. Typical install scenarios include bolted structural steel connections, machine frames, equipment mounting, and general mechanical assemblies where proof load integrity and corrosion resistance from the zinc yellow dichromate coating are both specified. Sold in a package quantity of 10 units per order.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance
• Partially threaded shank maintains a grip length for shear-load applications
• UNC 5/8-11 thread form for broad tool and nut compatibility
• Conforms to ASME B18.2.1 dimensional standards
• Sold in a package of 10 fasteners

Compatibility

Designed as an OEM-style and aftermarket replacement fastener for any application specifying a 5/8-11 UNC hex head cap screw in Grade 8 steel per ASME B18.2.1.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a standard hex wrench or socket set sized for a 5/8-inch hex head fastener. Always verify that the mating nut or tapped hole is rated for Grade 8 load requirements before assembly. De-energize and lock out all equipment before disassembling or replacing fasteners in a live mechanical or electrical assembly. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
