Professional Applications & Engineering Value

These M10 flat head screws with 1.5mm coarse thread pitch are engineered to solve critical fastening challenges in heavy machinery, industrial equipment, and structural applications. The zinc-plated alloy steel construction provides excellent corrosion resistance while maintaining the Class 12.9 strength rating, making them ideal for high-stress environments where vibration and dynamic loads are concerns. The flat head design with 90° countersink creates a flush surface finish, preventing snagging and improving safety in moving assemblies. With partial threading, these metric hex screws concentrate clamping force precisely where needed, reducing material stress and improving joint integrity. The combination of 170,000 psi tensile strength and standardized DIN 7991 compliance ensures reliable performance in automotive, construction, and manufacturing applications requiring high-strength fasteners.

Specification Summary & Compliance

This M10 x 1.5mm metric screw features precise Class 5g6g thread fit tolerance with coarse thread spacing and 26mm minimum thread length. Manufactured to DIN 7991 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 60mm length and standard flat head profile ensure dimensional consistency across applications, while the right-hand thread direction and 6mm hex drive size provide industry-standard installation compatibility.
