The VALUE COLLECTION 451129BR is a Grade 8 steel hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. Measuring 5/8-11 thread size with a 10-inch length under head, this fastener features Unified National Coarse (UNC) threading and a partially threaded shank. The bright, uncoated finish is suitable for dry or controlled environments. Manufactured to ASME B18.2.1 standards, it meets dimensional and mechanical requirements expected by engineers and tradespeople working to specification. At 0.9 pounds, it is sized for heavy-duty bolted connections where shear and tensile strength are critical.
This cap screw is suited for use in heavy equipment assembly, structural steel connections, agricultural machinery, and general industrial fabrication where Grade 8 strength is required. The partial threading allows the unthreaded shank to bear shear loads, making it appropriate for clevis pins, pivot joints, and through-bolt applications. Licensed millwrights, ironworkers, pipefitters, and general maintenance tradespeople commonly install fasteners of this type in both field and shop settings.
Designed as a standard 5/8-11 UNC Grade 8 hex head cap screw compatible with any application requiring ASME B18.2.1-compliant fasteners of this thread size and length.
Installation should be performed by qualified tradespeople familiar with fastener torque requirements for Grade 8 hardware — consult applicable engineering specifications or fastener torque charts for proper clamp load. Always ensure mating threads are clean and free of damage before assembly. Do not use impact tools at full power without verifying torque compliance. Follow applicable codes and job specifications when used in structural or pressure-bearing assemblies.
