Professional Applications & Engineering Value

This M16 shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automation systems, and heavy-duty equipment. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, extending service life in moist or chemically aggressive settings. The 16mm shoulder diameter with minimal tolerance ensures accurate component positioning, reducing wear and misalignment in rotating assemblies. Combined with a Class 5g6g thread fit and coarse 2mm pitch, it offers rapid installation and reliable hold in high-vibration environments like conveyor systems or robotic arms. The socket head with hex drive and knurled texture allows for efficient torque application, streamlining maintenance in confined spaces while supporting loads up to 70,000 psi tensile strength.

Specification Summary & Compliance

This metric shoulder screw adheres to precise dimensional standards, including a shoulder diameter tolerance of -0.04 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm. The thread fit conforms to Class 5g6g for consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial applications.
