Value Collection 643055PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 643055PR is a metric hex head cap screw built to Grade 8.8 steel specifications. It features an M8 x 1.25 thread profile with a 60 mm length under head and is fully threaded from tip to head bearing surface. The 13 mm hex drive allows standard wrench or socket engagement. At Grade 8.8, the fastener delivers a tensile strength suitable for structural and mechanical assemblies where medium-high clamping force is required. The bright, uncoated finish reflects the raw steel surface without additional plating or coating treatment. This screw is installed by millwrights, maintenance technicians, assemblers, and mechanical contractors across a wide range of industrial and commercial applications.

This fastener is used in general mechanical assembly, equipment mounting, structural fabrication, and maintenance repair operations requiring metric fasteners. The fully threaded shank provides uniform thread engagement across the full grip length, making it well suited for through-bolting and close-tolerance assemblies. It conforms to DIN 933 and ISO 4017 standards, which define dimensional and mechanical requirements for metric hex head screws with full threading. Typical install scenarios include machinery frames, brackets, flanges, and fabricated steel structures.

Key Features

• 13 mm hex drive compatible with standard metric wrenches and sockets
• Bright, uncoated finish — no plating or coating applied
• Metric thread standard for use in metric-specified assemblies

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017 dimensional specifications, suitable for use in any metric-threaded M8 x 1.25 application requiring a fully threaded fastener.

Installation Notes

Installation is performed by qualified mechanical trades or maintenance personnel using standard metric hand tools or powered fastening equipment. Apply appropriate torque for Grade 8.8 M8 fasteners per the relevant equipment or structural specification — do not use torque values not specified in the host equipment documentation. Ensure mating threads are clean and free of debris before driving. Follow applicable standards such as ASME or ISO fastener assembly guidelines for proper clamp load and joint integrity.
