Value Collection MP30165-4 Hex Cap Screw 7/8-9 X 4 in Grade 5

Product Description

The VALUE COLLECTION MP30165-4 is a 7/8-9 UNC hex head cap screw designed for general industrial and mechanical fastening applications. Measuring 4 inches under the head with partial threading, it provides a strong bearing surface in the unthreaded shank area, making it well-suited for clamping applications where shear load transfer is important. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance. Licensed mechanics, millwrights, pipefitters, and maintenance technicians commonly specify this fastener size for structural connections, equipment mounting, and heavy-duty assembly work.

This screw is used across residential and commercial maintenance, light structural assembly, and equipment installation in HVAC, plumbing, and general industrial settings. The 7/8-9 thread size and 4-inch length under head make it appropriate for thick material stacks or applications requiring a longer grip length. It is sold in packages of 10, making it practical for job-lot or service-truck stocking.

Key Features

• 7/8-9 UNC thread for broad compatibility with standard inch-series hardware
• 4-inch length under head with partial threading to provide an unthreaded shank for shear load applications
• Grade 5 steel construction meets medium-strength fastener requirements
• Zinc-plated finish provides basic corrosion protection in dry to mildly humid environments
• Packaged in quantities of 10 for convenient job-site use

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use with 7/8-9 UNC threaded holes and standard nuts in general mechanical and industrial fastening applications.

Installation Notes

Installation is performed by maintenance technicians or tradespeople using standard 1-5/16-inch hex wrenches or sockets. Always ensure mating threads are clean and free of debris before installation. De-energize and lock out equipment per applicable safety procedures before fastening or removing hardware in powered systems. Do not exceed the rated capacity of Grade 5 fasteners by substituting them in applications specifying Grade 8 or higher.
