Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and corrosion challenges in industrial applications. The 316 Stainless Steel material provides exceptional resistance to chemicals and moisture, making it suitable for food processing, marine, and pharmaceutical equipment. The hex socket drive and knurled head ensure secure torque application, reducing installation errors. The precisely machined shoulder (14 mm length) acts as a stable pivot or spacer, maintaining component alignment in assemblies like rotating machinery, jigs, and automation systems. Its coarse pitch thread (1.75 mm) allows for quick assembly and disassembly, while the Class 5g6g thread fit guarantees consistent engagement, minimizing backlash and vibration-related failures.
Specification Summary & Compliance
This metric shoulder screw adheres to ISO metric thread standards with a Class 5g6g thread fit for dimensional accuracy. Key tolerances include a shoulder diameter of 20 mm (-0.072 to -0.01 mm) and shoulder length of 14 mm (0 to 0.25 mm). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial markets.
