Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and durability challenges in precision machinery, automation systems, and corrosive environments. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, preventing failure in applications like marine equipment or food processing. The 16mm shoulder diameter with controlled tolerances acts as a precise locating feature, eliminating misalignment in rotating assemblies or linear guides. Combined with the coarse thread pitch and socket head design, it ensures quick, secure fastening in high-vibration settings, reducing maintenance downtime and enhancing operational reliability for OEMs and MRO professionals.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit ensuring dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, guaranteeing precise fits. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and restricted substance-controlled applications.
