Value Collection 644052PS Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 644052PS is a metric hex head cap screw designed for general-purpose fastening applications requiring a partially threaded shank. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 931 and ISO 4014 standards. The M8 x 1.25 thread profile and 50 mm length under head make it suitable for medium-duty clamping and assembly work across a wide range of mechanical, structural, and equipment maintenance tasks. The 13 mm hex drive is compatible with standard metric wrenches and sockets.

This cap screw is used in industrial maintenance, mechanical assembly, and structural fastening applications where a partially threaded bolt is required to allow the unthreaded shank to bear shear loads or align mating parts. Common installation scenarios include machine frames, brackets, flanges, and equipment enclosures. It is appropriate for use by millwrights, machinists, maintenance technicians, and field service professionals working with metric hardware.

Installation Notes

Installation is performed with a standard 13 mm metric wrench or socket. Always verify thread engagement depth and mating material specifications before torquing. Follow applicable industry torque tables for Grade 8.8 M8 fasteners; do not exceed the rated proof load of the fastener or the clamping material. Inspect threads for damage before installation and discard any fasteners with deformed, cross-threaded, or corroded threads.
