Professional Applications & Engineering Value

These M10 metric hex socket button head screws deliver critical engineering solutions for industrial applications requiring both high tensile strength and corrosion resistance. The blue-dyed zinc-plated alloy steel construction provides superior protection against environmental factors, while the Class 10.9 strength rating ensures reliable performance in heavy-duty assemblies. The fully threaded coarse pitch design (M10 x 1.5mm) enables rapid installation in machinery, automotive components, and structural frameworks where vibration resistance is crucial. The hex socket button head configuration allows for flush mounting in confined spaces while maintaining high torque capability. These metric fasteners are engineered to prevent stripping and maintain integrity under dynamic loads, making them ideal for precision equipment, manufacturing fixtures, and industrial machinery requiring repeated maintenance access.

Specification Summary & Compliance

This M10 x 1.5mm x 40mm Class 10.9 metric screw features precise Class 6g thread fit tolerances and fully threaded coarse pitch design per ISO 7380 standards. The fastener maintains Rockwell C32 hardness and 140,000 psi tensile strength throughout its service life. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The rounded button head profile with 17.5mm diameter and 5.5mm height provides optimal bearing surface while the 6mm hex drive ensures consistent torque application.
