Value Collection MP4540 Hex Head Cap Screw M12 X 1.25

Product Description

The Value Collection MP4540 is a metric hex head cap screw designed for general-purpose fastening applications in mechanical assemblies, equipment maintenance, and structural connections. Built to Grade 8.8 steel with a zinc-plated finish, this screw delivers solid tensile strength and basic corrosion resistance for a wide range of shop and field uses. The M12 x 1.25 thread pitch is a fine-pitch metric standard, and the 20 mm length under head keeps it suited to close-tolerance assemblies where thread engagement depth matters. A 17 mm hex drive allows installation with standard metric wrenches or sockets. The fully threaded shank maximizes thread engagement across the full bearing length. Sold in packages of 25.

This fastener is appropriate for automotive, industrial, and equipment repair applications that specify fine-pitch M12 metric fasteners. Grade 8.8 classification makes it suitable for medium- to high-strength clamping loads in steel-to-steel joints. The zinc plating provides a baseline level of corrosion protection for indoor and light outdoor environments. Installers working to JIS B1180-7 specifications will find this screw meets that standard directly. Package quantity of 25 supports small-batch repair work and production line restocking alike.

Compatibility

Designed for use in metric fastening applications requiring an M12 x 1.25 fine-pitch hex head cap screw conforming to JIS B1180-7.

Installation Notes

Installation is typically performed by mechanics, millwrights, or maintenance technicians using a 17 mm wrench or socket. Always verify the mating thread is M12 x 1.25 fine pitch before installation, as fine-pitch and coarse-pitch M12 fasteners are not interchangeable. Follow applicable torque specifications from the equipment manufacturer for Grade 8.8 hardware. Inspect threads for damage before installation and do not install a cross-threaded or galled fastener.
