• Heavy-duty construction rating with Class 8.8 strength grade and Rockwell C22 hardness for structural and machinery applications
• Universal compatibility with standard 1-1/16" holes and full threading for consistent performance across 1/2" to 1-1/8" material thicknesses
• Regulatory compliance assurance meeting international ISO 4017/DIN 933 standards and environmental RoHS 3/REACH requirements

Professional Applications & Engineering Value

These M16 hex head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The expanding sleeve locking mechanism prevents loosening in heavy machinery, construction equipment, and industrial assemblies subject to constant stress cycles. Manufactured from Class 8.8 zinc-plated steel, these fully threaded metric fasteners provide exceptional corrosion protection while maintaining 110,000 psi tensile strength - significantly reducing failure risks in load-bearing applications. The coarse 2mm thread pitch enables rapid installation in structural steel, manufacturing equipment, and transportation infrastructure where time efficiency and reliable fastening are equally critical. These screws are engineered to withstand extreme operational demands while maintaining clamping force through their innovative locking design.

Specification Summary & Compliance

This M16 x 2mm hex head screw features Class 6g thread tolerance with right-hand coarse threading and complies with ISO 4017/DIN 933 manufacturing specifications. The fastener meets Class 8.8 strength requirements with verified Rockwell C22 hardness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Designed for use with standard 1-1/16" holes, these screws provide precise fitment across their specified material thickness range while maintaining dimensional accuracy per international metric standards.
