Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M16 hex head screws address critical vibration and load challenges in machinery, structural steel, and equipment assembly. The zinc-plated steel construction provides essential corrosion protection while maintaining Class 8.8 strength for high-stress connections. The expanding sleeve locking mechanism prevents loosening under dynamic conditions, making these metric coarse thread fasteners ideal for applications requiring secure, permanent fastening. With fully threaded design and precise M16x2 mm threading, they ensure maximum thread engagement and uniform stress distribution across joints from 2" to 2 13/16" thickness.
Specification Summary & Compliance
These hex head screws feature M16x2 mm coarse threads with Class 6g tolerance and fully threaded design per ISO 4017/DIN 933 standards. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable industrial use. The Class 8.8 strength rating and Rockwell C22 hardness guarantee consistent mechanical performance across applications.
