Value Collection MP30145-4 Hex Head Cap Screw 5/8-11 X 4 in

Product Description

The VALUE COLLECTION MP30145-4 is a partially threaded hex head cap screw sized 5/8-11 x 4 inches, manufactured from Grade 5 steel with a zinc-plated finish. It follows the Unified National Coarse (UNC) thread standard and meets ASME B18.2.1 dimensional specifications. This fastener is designed for general mechanical assemblies, structural connections, and equipment mounting applications where moderate-strength steel hardware is required. Length measurement is taken under the head. It is sold in packages of 10 and is installed by maintenance technicians, millwrights, pipefitters, and other trade professionals working with standard inch-series fasteners.

This cap screw is suited for a wide range of industrial and commercial applications including HVAC equipment frames, pump and motor mounts, pipe hangers, electrical enclosure assemblies, and general mechanical fabrication. The 5/8-11 thread size is a common coarse-thread specification found throughout industrial and trade equipment. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for bolted joints where shear strength is a design consideration.

Key Features

• Grade 5 steel construction provides medium-high tensile strength for general mechanical assemblies
• Zinc-plated finish offers basic corrosion resistance in indoor and sheltered environments
• Partially threaded shank supports shear load applications
• UNC thread form (5/8-11) is a widely stocked, standard inch-series specification
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Packaged in quantities of 10 for job-site and shop convenience

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/8-11 UNC thread pattern with a 4-inch length under head. Compatible with standard 5/8-11 hex nuts, flat washers, and lock washers conforming to ASME inch-series standards.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 5/8-inch hex head cap screw. Apply appropriate thread lubricant or thread locker as required by the assembly specification. Torque to the value specified by the equipment manufacturer or relevant structural code for Grade 5 fasteners. Inspect threads for damage before installation and do not reuse fasteners that show signs of galling, corrosion, or deformation.
