Professional Applications & Engineering Value
This M16 hex head screw delivers exceptional engineering value by addressing common industrial challenges like corrosion, vibration, and assembly speed. Crafted from 18-8 Stainless Steel, it resists rust and chemical exposure, making it suitable for outdoor machinery, marine equipment, and food processing plants. The coarse metric thread with a 2mm pitch ensures rapid installation and maintains hold in high-vibration environments, such as automotive frames or construction assemblies. Its partially threaded design focuses clamping force on critical sections, reducing the risk of strip-out in softer materials. With an external hex drive, technicians can achieve tight torque control using common wrenches, streamlining maintenance and reducing downtime in heavy-duty applications.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including Class 6g thread fit per ISO metric specifications for consistent engagement. It meets ISO 4014 and DIN 931 manufacturing norms, ensuring reliable performance in mechanical fastening. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable use in industrial sectors.
