Value Collection MPKP44114 5/8-11 X 2 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION MPKP44114 is a fully threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Manufactured from Grade 8 steel with a zinc-plated finish, it meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 5/8-11 UNC thread and 2-inch length under head provide solid clamping force in medium to heavy-duty fastening scenarios. The zinc plating adds a baseline layer of corrosion resistance for general indoor and sheltered outdoor use. Sold in packages of 10, this screw is a practical stocking item for shops, service trucks, and maintenance crews.

This hex cap screw is used across a wide range of trade applications including HVAC equipment mounting, mechanical room installations, structural brackets, pump and motor assemblies, and general equipment fastening. The 5/8-11 UNC thread is one of the most common heavy-duty coarse-thread sizes in North American trade work, fitting standard hex nuts, flange nuts, and tapped holes of the same designation. Grade 8 classification makes it appropriate where higher tensile strength is required compared to Grade 5 or Grade 2 fasteners.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength
• Fully threaded along the 2-inch shank for maximum thread engagement
• 5/8-11 UNC coarse thread — widely compatible with standard nuts and tapped components
• Zinc-plated finish provides baseline corrosion resistance for general service environments
• Packaged in quantities of 10 for convenient stocking and job-site use

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts, lock nuts, and flange nuts. Compatible with any application requiring a fully threaded Grade 8 hex cap screw in the 5/8-11 coarse thread specification.

Installation Notes

Installation is typically performed by millwrights, pipefitters, HVAC mechanics, or general maintenance technicians using a standard 15/16-inch hex wrench or socket. Always verify the mating thread specification and grade rating before installation in structural or load-bearing applications. Follow applicable industry standards and equipment manufacturer torque guidelines when specified. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts not rated for the same load class.
