The VALUE COLLECTION 644322PS is a metric hex head cap screw rated to Grade 8.8 steel construction and supplied in an uncoated, bright finish. Sized M24 x 3.00 with a 140 mm length under head, this fastener features partial threading and a 36 mm hex drive. Grade 8.8 designates medium-high tensile strength suitable for structural and mechanical assemblies where clamping force and fatigue resistance are required. Manufactured to DIN 931 and ISO 4014 standards, it is a widely recognized fastener profile used by millwrights, pipefitters, mechanical contractors, and maintenance technicians working on industrial and commercial equipment.
This screw is suited for bolted flange connections, equipment mounting, structural steel fabrication, and heavy mechanical assemblies that call for a partially threaded metric fastener. The partial thread shank provides a clean bearing surface in close-tolerance holes, making it appropriate for applications where shear load distribution matters. It is commonly installed in HVAC equipment frames, pump and motor mounts, piping supports, and general industrial maintenance situations requiring a DIN 931 or ISO 4014 compliant fastener.
Designed as a standard metric replacement or service fastener conforming to DIN 931 and ISO 4014 specifications for M24 x 3.00 partially threaded hex head cap screw applications.
Installation is typically performed by qualified millwrights, mechanical contractors, or maintenance technicians using calibrated torque wrenches and metric impact sockets. Always de-energize, depressurize, or otherwise render safe any equipment before loosening or replacing structural fasteners. Consult the equipment manufacturer torque specification tables for the assembly being serviced, as appropriate clamp load depends on joint material, lubrication condition, and fastener grade. Follow applicable ASME, AISC, or equipment OEM guidelines for fastener installation in structural and pressure-boundary joints.
