Professional Applications & Engineering Value

This M4 shoulder screw is engineered to address critical alignment and wear issues in precision assemblies. The 316 Stainless Steel material offers superior resistance to chemicals and corrosion, making it suitable for marine, chemical processing, and food-grade equipment. The 10mm shoulder length acts as a precise spacer or pivot, reducing wear on moving parts and maintaining alignment in industrial machinery, robotics, and automotive jigs. The hex socket head allows for high-torque installation in confined spaces, while the Class 5g6g coarse thread ensures quick assembly and vibration resistance. This combination of a durable shoulder screw with a right-hand thread and robust surface finish delivers long-term reliability, minimizing maintenance and downtime in high-performance environments.

Specification Summary & Compliance

This precision shoulder screw features an M4 x 0.7mm coarse metric thread with a Class 5g6g fit, ensuring dimensional accuracy and interchangeability. The shoulder diameter is 6mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 10mm with a tolerance of 0 to 0.25 mm, providing consistent performance. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets stringent environmental and safety standards for global industrial use.
