- Optimized thread engagement with M16 coarse 2mm pitch and Class 6g fit, providing quick assembly and vibration resistance
- Versatile partial threading (38mm min thread length on 60mm shank) for precise clamping control in varied material thicknesses
- Full regulatory compliance with RoHS 3 and REACH, making them safe for use in regulated industrial environments
- Global interoperability through ISO 4014 DIN 931 standardization, ensuring consistent quality and replacement compatibility
Professional Applications & Engineering Value
These M16 hex head screws deliver critical engineering value in heavy machinery, structural steel connections, and industrial equipment assembly. The Class 10.9 steel construction provides exceptional resistance to dynamic loads and fatigue, while the coarse metric thread with 2mm pitch prevents loosening in high-vibration environments. The partially threaded design allows unthreaded shank sections to bear shear loads directly, reducing thread wear in bolted joints. With external hex drive compatibility, they enable rapid installation using standard tools, significantly reducing assembly time in manufacturing and maintenance operations where high tensile strength and reliability are paramount.
Specification Summary & Compliance
Manufactured to ISO 4014 DIN 931 specifications with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The screws feature metric coarse threading (M16x2mm) with right-hand direction and 38mm minimum threaded length on a 60mm overall fastener. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across industrial sectors.
