Professional Applications & Engineering Value
These Class 10.9 metric rounded head screws deliver critical performance where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction provides superior protection against corrosion in manufacturing equipment, automotive assemblies, and heavy machinery applications. The fully threaded M6 x 1 mm coarse spacing ensures maximum thread engagement in both metallic and high-density plastic components, while the button head profile offers a low-profile solution for clearance-restricted assemblies. The 4 mm hex drive design prevents cam-out during high-torque installation, reducing assembly time and tool wear. Engineered to ISO 7380 standards, these fasteners provide consistent dimensional accuracy for automated assembly systems and maintenance operations.
Specification Summary & Compliance
This M6 x 1 mm metric screw features Class 6g thread fit tolerance and 16 mm length with full threading. Manufactured to ISO 7380 specifications for dimensional consistency and performance reliability. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulatory adherence for international industrial applications. Material certification confirms Class 10.9 strength grade with 140,000 psi tensile strength and Rockwell C32 hardness verification.
