Value Collection KP44116 Hex Head Cap Screw 5/8-11 Grade 8

Product Description

The VALUE COLLECTION KP44116 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and trade service work. Measuring 5/8-11 thread size with a 2-1/2 inch length under head, this partially threaded fastener meets ASTM A354 BD standards for mechanical performance. A zinc-plated finish provides corrosion resistance suitable for general service environments. Sold in a package of 25, this screw follows Unified National Coarse (UNC) thread standards and is intended for use by mechanics, millwrights, pipefitters, and general trade professionals requiring reliable, code-recognized fasteners.

This hex head cap screw is suited for structural and mechanical assembly work across residential and commercial applications. The 5/8-11 UNC thread is a common size in heavy-duty equipment mounting, pipe support fabrication, HVAC equipment bases, electrical panel and conduit support structures, and general mechanical installations. The partially threaded shank provides a grip length that improves clamping force in through-bolted connections. The Grade 8 rating makes it appropriate where higher proof load and tensile strength are required compared to Grade 5 or Grade 2 fasteners.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using an appropriately sized hex or socket wrench. Always ensure mating threads are clean and free of damage before installation. Consult applicable codes such as AISC or equipment manufacturer torque specifications before final assembly. Do not use impact tools without verifying thread and material compatibility.
