ZUBEHÖR kuusiokoloruuvi M10x40 mm DIN 912 teräs 8.8 30001187

When a standard bolt is too bulky or a hex head would snag on moving parts, you need a fastener that sits flush and transfers torque reliably. The ACCESSORY M10x40mm hexagon socket head cap screw solves that with a cylindrical head that fits into counterbored holes, driven by an 8 mm Allen key for a clean, secure assembly.

Who is it for

Maintenance technicians, machine builders, and anyone assembling equipment where a low-profile, high-strength joint is essential. If you work with metric machinery, jigs, or fixtures, this screw gives you the clamping force of a grade 8.8 bolt without the protruding head.
