Value Collection MP39159 Hex Head Cap Screw 5/8-11 X 5 in Grade 8

Product Description

The VALUE COLLECTION MP39159 is a Grade 8 steel hex head cap screw sized 5/8-11 x 5 inches, finished in zinc yellow dichromate for corrosion resistance in demanding environments. It features partial threading along the shank and conforms to ASME B18.2.1 dimensional standards. This fastener is intended for high-strength bolted connections in industrial, mechanical, and structural applications where a coarse UNC thread profile and a durable protective coating are required. Each package contains 10 screws.

This screw is suited for use in heavy equipment assembly, structural fabrication, and general mechanical installations where Grade 8 tensile strength is specified. The 5/8-11 UNC coarse thread engages reliably with standard tapped holes and matching nuts. The partial threading allows for precise clamping and shank engagement in through-bolt configurations. Maintenance technicians, millwrights, and structural ironworkers commonly use this fastener type across a range of commercial and industrial settings.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Partially threaded shank suits through-bolt and tight-tolerance applications
• 5/8-11 UNC coarse thread for broad compatibility with standard hardware
• Conforms to ASME B18.2.1 for dimensional consistency
• Sold in a 10-piece package with a minimum order quantity of 1

Compatibility

Designed as a standard-dimension replacement or service fastener for any application requiring a 5/8-11 UNC coarse thread hex head cap screw at 5 inches length under head, per ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or technician familiar with high-strength fastener torque requirements for Grade 8 hardware. Always consult the equipment manufacturer's torque specification table before final tightening — do not estimate. Inspect mating threads for damage or contamination before assembly, and ensure the fastener is not cross-threaded during engagement. De-energize, depressurize, or lock out the equipment per applicable OSHA lockout/tagout procedures before servicing any bolted joint.
