Value Collection 97453 Hex Cap Screw 5/8-18 X 3 in Grade 5

Product Description

The VALUE COLLECTION 97453 is a partially threaded hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 5 steel with a bright, uncoated finish, this fastener features a 5/8-18 UNF thread size and a 3-inch length under head. The hex head design allows for standard wrench or socket installation. Built to ASME B18.2.1 dimensional standards, this screw delivers consistent fit and performance in assemblies where a recognized inch-series fastener specification is required. It is appropriate for use by maintenance technicians, millwrights, pipefitters, and general trade professionals working with bolted connections in steel structures or equipment.

This fastener is suited for use in residential, commercial, and light industrial mechanical assemblies requiring a fine-thread UNF fastener in the 5/8-inch diameter range. The partial threading leaves a smooth shank section beneath the head, which is advantageous in applications where the fastener passes through a clearance hole before engaging a tapped bore. Typical uses include equipment mounting, structural steel connections, and mechanical component assembly. This item is sold in a package quantity of 25.

Installation Notes

Installation should be performed by a qualified technician using an appropriate wrench or socket sized for the hex head. Always ensure the mating tapped hole or nut meets the same thread standard (UNF) before installation. Torque to the value specified by the equipment manufacturer or applicable engineering standard for Grade 5 fasteners of this diameter. Inspect threads on both the fastener and the mating component for damage before assembly.
