Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical challenges in precision machinery and industrial equipment. The 316 Stainless Steel material provides excellent resistance to corrosion and chemicals, making it ideal for applications in marine, chemical processing, and food industry environments where moisture and corrosive agents are present. The 16mm shoulder length and precise diameter tolerance act as a dependable pivot or spacer, minimizing radial play and absorbing lateral forces to protect sensitive components. Combined with the coarse thread (M6x1mm) and Class 5g6g thread fit, it ensures quick assembly and a secure hold, reducing the risk of thread stripping in softer materials. The knurled socket head with a 4mm hex drive enhances torque transmission and prevents cam-out, which is crucial for maintenance and high-vibration settings. This screw delivers reliable fastening solutions that enhance machine longevity and operational safety.

Specification Summary & Compliance

The screw features a Class 5g6g thread fit for standard clearance and ease of assembly. 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 accordance with ISO 7379 and is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety standards.
