Professional Applications & Engineering Value
These high-strength metric hex screws deliver critical engineering solutions for industrial assembly challenges where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, automotive components, and structural frameworks exposed to harsh operating conditions. The M10 coarse thread configuration enables rapid installation in production environments while maintaining secure fastening under dynamic loads. With fully threaded design and Class 10.9 strength rating, these rounded head screws distribute clamping forces evenly, preventing joint failure in heavy equipment, construction applications, and manufacturing assemblies where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M10x1.5 coarse thread maintaining Class 6g tolerance for consistent fit. The fastener meets ISO 7380 manufacturing specifications for dimensional accuracy and performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures safe use across regulated industries. The Class 10.9 strength classification corresponds to minimum tensile strength of 140,000 PSI with Rockwell C32 hardness, providing verified mechanical properties for critical applications.
