Professional Applications & Engineering Value

These Class 10.9 metric hex screws deliver exceptional engineering value through their black-oxide alloy steel construction and precision M6 x 1 mm coarse thread design. The combination of 140,000 psi tensile strength and Rockwell C32 hardness provides reliable performance in heavy-duty applications where vibration resistance and structural integrity are critical. The fully threaded configuration ensures maximum surface contact for superior clamping force, while the rounded button head profile offers a low-profile finish that reduces snagging hazards in machinery and equipment. Ideal for industrial assembly, automotive manufacturing, and construction applications, these ISO 7380 compliant fasteners solve common challenges of joint failure, corrosion degradation, and installation inefficiency in demanding environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 6g thread fit tolerance and ISO 7380 specifications for consistent performance. The metric coarse thread (M6 x 1 mm) with right-hand direction ensures compatibility with standard industrial components. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety standards, while the Class 10.9 strength rating and fully threaded 60mm length provide verified mechanical properties for critical applications.
