Value Collection R52001245 Hex Cap Screw 5/8-11 X 9 in Grade 5

Product Description

The VALUE COLLECTION R52001245 is a partially threaded hex head cap screw sized 5/8-11 x 9 inches, manufactured from Grade 5 steel with a zinc-plated finish. Designed to the Unified National Coarse (UNC) thread standard and compliant with ASME B18.2.1 and SAE J429, this fastener delivers the clamping strength and dimensional consistency required for structural and mechanical assemblies. The partial threading allows for a full-grip shank section, which resists shear loads in bolted joints. At 0.82 pounds, it is suited for heavy-duty fastening applications where torque retention and corrosion resistance are both priorities. Licensed tradespeople and maintenance technicians select this screw for reliable performance in demanding environments.

This hex head cap screw is appropriate for a wide range of industrial, mechanical, and construction fastening applications. The 5/8-11 thread size and 9-inch length under the head make it well suited for through-bolting thick structural members, equipment frames, flanged connections, and mechanical supports. The zinc-plated finish provides baseline corrosion resistance for indoor and lightly exposed outdoor installations. It is commonly installed by millwrights, maintenance mechanics, pipefitters, and general contractors working on structural steel, heavy equipment, and fabricated assemblies.

Installation Notes

Installation should be performed by qualified mechanics or tradespeople using a properly sized hex wrench or impact socket rated for 5/8-inch fasteners. Always verify the mating nut or tapped hole thread specification matches 5/8-11 UNC before installation. Apply a flat washer under the head when surface bearing area requires distribution. Follow applicable structural or equipment torque specifications from the assembly documentation; no torque value is specified for this fastener by the supplier.
