Professional Applications & Engineering Value
This M16 shoulder screw is engineered to address critical alignment and durability challenges in industrial assemblies. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in demanding conditions. The 120mm shoulder length with precise diameter tolerance acts as a reliable pivot or spacer, reducing wear on moving parts and ensuring accurate positioning in machinery, automation systems, and precision equipment. The Class 5g6g thread with a 2mm coarse pitch offers quick assembly and robust holding power, while the hex socket drive and knurled head facilitate secure tightening in confined spaces. This combination of features minimizes maintenance downtime and enhances the reliability of your mechanical designs.
Specification Summary & Compliance
The screw features a metric M16x2mm coarse thread with Class 5g6g tolerance for consistent fit. The shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for regulated industrial and international markets.
