The VALUE COLLECTION MP30087 is a hex head cap screw designed for general mechanical and structural fastening applications. It features a 7/16-14 UNC thread size with a 3-inch length under head and is partially threaded, making it suitable for through-bolting applications where a clamping grip is required. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable tensile strength and basic corrosion resistance for indoor and light outdoor use. Licensed mechanics, millwrights, pipefitters, and maintenance technicians routinely specify Grade 5 hex cap screws for mid-duty fastening in machinery, equipment frames, and structural assemblies.
This screw is used across a wide range of trade and industrial settings, including HVAC equipment mounting, mechanical room installations, electrical panel support structures, pump and motor mounting, and general equipment assembly. The UNC thread standard ensures broad compatibility with standard tapped holes and hex nuts across American inch-based hardware. Sold in a package quantity of 10, this fastener is appropriate for both single-task repairs and small-batch maintenance work.
Designed as a standard 7/16-14 UNC hex head cap screw suitable for use with matching hex nuts, lock nuts, and flat washers in American inch-based fastening applications across mechanical, HVAC, plumbing, and electrical support structures.
Installation is performed using standard hand tools including a combination wrench or socket set sized for a 7/16-14 hex head. Ensure the mating tapped hole or nut matches the UNC thread standard before installation. Apply thread lubricant or anti-seize compound where corrosion or galling is a concern. Always follow applicable mechanical codes and equipment manufacturer guidelines when specifying fastener grade and torque for structural or load-bearing connections.
