Value Collection 97154 Hex Cap Screw 5/8-11 Grade 5 25pk

Product Description

The VALUE COLLECTION 97154 is a 5/8-11 hex head cap screw with a 3-1/4 inch length under head, manufactured from Grade 5 steel with an uncoated finish. The screw features a Unified National Coarse (UNC) thread form and is partially threaded, conforming to ASME B18.2.1 dimensional standards. Sold in a package of 25, this fastener is suited for general industrial and mechanical assembly work where Grade 5 tensile strength is specified. Licensed contractors, millwrights, pipefitters, and maintenance technicians reach for this size when assembling structural connections, flanges, and equipment frames that require a medium-strength fastener in a standard inch-system thread.

The 5/8-11 UNC thread size and 3-1/4 inch grip length make this screw a common choice in commercial and industrial settings. Typical applications include bolting steel structural members, machinery bases, pump flanges, and heavy equipment brackets. The partially threaded shank provides a smooth bearing surface in the grip zone, which helps resist shear loads in joints where the bolt passes through multiple material layers. The uncoated finish is appropriate for dry indoor environments or applications where a field-applied coating or plating will be specified separately.

Compatibility

Designed as a standard inch-system hex head cap screw for use in any bolted connection specifying a 5/8-11 UNC thread and a Grade 5 steel fastener per ASME B18.2.1.

Installation Notes

Installation is typically performed by a qualified mechanic, millwright, or pipefitter using appropriate hand or power tools rated for the fastener size. Always de-energize and lock out equipment before servicing any bolted connection on live machinery. Torque to the value specified in the applicable equipment or structural engineering documentation for Grade 5 fasteners of this diameter. Inspect threads for damage before installation and ensure mating nut or tapped hole threads are clean and undamaged.
