Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 316 stainless steel material provides exceptional resistance to chemicals and moisture, preventing failure in corrosive settings like marine or chemical processing equipment. The integrated 15mm shoulder acts as a precise pivot or spacer, eliminating the need for additional bushings and reducing assembly complexity in machinery, conveyor systems, and precision instruments. Combined with the knurled socket head and coarse thread pitch, it ensures quick, secure fastening that withstands high vibration and dynamic loads, enhancing overall equipment reliability and reducing maintenance downtime.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm coarse thread with Class 5g6g thread fit per metric standards. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring high precision. It is manufactured to meet ISO 7379 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
