Professional Applications & Engineering Value

This M16x2mm shoulder screw is engineered to address critical alignment and stability challenges in precision machinery. The 316 stainless steel material provides excellent resistance to corrosion and high temperatures, making it suitable for applications in chemical processing, marine equipment, and food machinery. The black oxide finish enhances durability and reduces friction, minimizing the risk of seizing under dynamic loads. With a 70mm shoulder length and precise 20mm diameter, it ensures accurate component positioning, eliminating misalignment in assemblies like rotating shafts, linkages, and bearing supports. The coarse thread design and hex socket drive facilitate quick, secure installation, reducing assembly time and improving maintenance efficiency in industrial shoulder bolt applications.

Specification Summary & Compliance

This metric shoulder screw features M16x2mm coarse threads with a Class 5g6g thread fit for reliable engagement. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with ISO 7379 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, guaranteeing safety and regulatory adherence for global supply chains.
