Value Collection KP60621 M8 X 1.25 Flange Bolt Grade 10.9 25-pack

Product Description

The VALUE COLLECTION KP60621 is a smooth flange bolt designed for metric fastening applications requiring high-strength clamping without a separate washer. The integrated smooth flange distributes load across an 18 mm flange diameter, reducing surface damage on mated parts. The bolt is M8 x 1.25, fully threaded along its 25 mm length under head, and manufactured from Grade 10.9 alloy steel with a zinc-plated finish for corrosion resistance. Drive is a 12.73 to 13 mm hex. This fastener is sold in a package of 25 and is suited for use in mechanical assemblies, equipment fabrication, and structural connections where metric fastening standards apply.

This bolt is a common choice in manufacturing, maintenance, and assembly environments where metric hardware is specified. The fully threaded shank allows engagement along the full fastener length, making it effective for thin-material connections and through-bolt applications. Compliance with DIN 6921 and DIN ISO 898-1 makes it appropriate for engineered assemblies that require documented fastener standards. It is typically installed by maintenance technicians, machine builders, and mechanical contractors working within metric design systems.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians using a standard metric hex wrench or socket driver. De-energize and lock out any equipment before accessing fastener locations on live machinery. Grade 10.9 fasteners should not be substituted with lower-grade hardware in load-bearing or safety-critical applications. Follow the torque specifications defined by the equipment manufacturer or applicable engineering standards for M8 Grade 10.9 fasteners.
