Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M16 hex head screws deliver critical performance where vibration resistance and structural integrity are paramount. The Class 10.9 steel construction combined with fully threaded design ensures maximum clamping force distribution across the entire 110mm length, preventing joint loosening in machinery, structural steel connections, and equipment assembly. The black oxide finish provides essential corrosion protection in manufacturing environments while maintaining dimensional stability. With coarse metric threading and external hex drive, these fasteners enable rapid installation and removal in maintenance operations, reducing downtime in production facilities, construction projects, and automotive applications where high tensile strength and reliability are non-negotiable requirements.

Specification Summary & Compliance

Manufactured to DIN 933 specifications with Class 6g thread tolerance ensuring precise fit and interchangeability. The metric coarse thread (M16x2mm) provides optimal engagement in various materials while the fully threaded 110mm length maintains consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for international industrial markets. The right-hand thread direction and external hex drive conform to global fastener standards for seamless integration into existing assembly processes.
