Value Collection MP39092 Hex Cap Screw 7/16-14 X 4.5 in Grade 8

Product Description

The VALUE COLLECTION MP39092 is a partially threaded hex head cap screw designed for heavy-duty fastening applications across industrial, mechanical, and structural assembly work. It features a 7/16-14 UNC thread size and a length under head of 4-1/2 inches, giving it the grip length needed for thicker material stack-ups. Manufactured from Grade 8 steel, it delivers high tensile strength suitable for demanding bolted joints. A zinc yellow dichromate finish provides corrosion resistance in environments where bare steel would be vulnerable. This fastener conforms to ASME B18.2.1 and SAE J429 standards, ensuring dimensional and mechanical consistency. Sold in a package of 10.

This cap screw is suited for general mechanical assembly, equipment mounting, structural connections, and maintenance repair operations across industrial and commercial settings. The partial thread configuration allows the unthreaded shank to bear shear loads while the threaded portion engages the nut or tapped hole. Typical installers include millwrights, maintenance technicians, pipefitters, and general contractors working with bolted steel assemblies that require a high-strength, inch-series fastener.

Installation Notes

Installation of Grade 8 fasteners should be performed by qualified technicians familiar with proper torque procedures for high-strength bolted joints. Always ensure the mating nut or tapped hole is rated to a compatible grade and thread specification before assembly. De-energize and lock out any equipment before replacing or servicing fasteners on machinery. Follow applicable industry standards and equipment manufacturer guidelines for torque and preload requirements.
