Value Collection MPKP44124 Hex Cap Screw 5/8-11 X 5 in Grade 8

Product Description

The VALUE COLLECTION MPKP44124 is a partially threaded hex head cap screw designed for high-strength fastening applications in structural, mechanical, and industrial assemblies. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards, making it suitable for demanding load-bearing connections. The 5/8-11 UNC thread profile and 5-inch length under head provide the clamping force and grip length needed for heavy-duty bolted joints. Machinists, millwrights, maintenance technicians, and contractors reach for Grade 8 hardware when joint integrity under dynamic or high-stress loading is a requirement.

This cap screw is appropriate for use in general industrial machinery, structural steel connections, heavy equipment fabrication, and maintenance applications where a high-strength, corrosion-resistant fastener is specified. The zinc-plated finish provides a baseline level of corrosion protection suitable for indoor and mildly exposed environments. Partial threading allows the unthreaded shank to act as a close-tolerance locating feature in bolted joint designs where shear loading is a factor. Sold in a package of 5.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or technician familiar with bolted joint specifications. Always verify the mating thread size and material compatibility before installation. Power down and de-energize or de-pressurize any equipment before servicing fastened assemblies. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards, as no torque value is specified for this fastener in the available product data.
