Professional Applications & Engineering Value
This M12 shoulder screw is engineered to solve critical alignment and strength challenges in precision assemblies. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, making it suitable for automotive, machinery, and electronic enclosures exposed to moisture or chemicals. The 50mm shoulder length acts as a precise pivot or spacer, eliminating the need for additional bushings and reducing assembly time. Combined with the coarse metric thread and knurled socket head, it ensures secure fastening in high-vibration environments, preventing loosening and maintaining structural integrity. Its compliance with international standards guarantees reliability in global supply chains.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per ISO metric standards, ensuring precise tolerance. The shoulder diameter is 16mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 50mm with a 0 to 0.25 mm tolerance. It conforms to ISO 7379 for dimensional accuracy, and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming it is free of hazardous substances and safe for various industrial applications.
