Professional Applications & Engineering Value

This M16 shoulder screw is engineered from 18-8 stainless steel to address common industrial challenges like corrosion and mechanical failure. Its coarse thread pitch of 2mm and right-hand thread direction enable quick assembly in high-vibration applications, such as machinery and automotive systems. The 20mm shoulder diameter and 35mm shoulder length provide stable support for rotating components, reducing wear and misalignment. With a Rockwell B83 hardness and hex socket drive, it withstands repetitive use without stripping, making it ideal for precision equipment and heavy-duty fixtures where durability and corrosion resistance are critical.

Specification Summary & Compliance

This shoulder screw adheres to ISO 7379 standards, with a Class 5g6g thread fit for precise tolerances. The shoulder diameter tolerance ranges from -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility in industrial use.
