Professional Applications & Engineering Value
This M8x1.25 shoulder screw in 316 stainless steel is engineered to address critical alignment and corrosion challenges in precision assemblies. Its 12mm shoulder length with tight tolerances ensures accurate positioning of components like bearings, gears, and linkages, minimizing misalignment and vibration. The coarse thread (M8x1.25) and Class 5g6g thread fit provide secure fastening with high repeatability, while the knurled head and 5mm hex drive allow for easy handling and torque application in confined spaces. Ideal for industrial machinery, automotive systems, and marine equipment, this screw offers long-term reliability by resisting chemical exposure and mechanical stress, reducing maintenance needs and downtime.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a Class 5g6g thread fit for dimensional accuracy. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precise fits. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances and suitable for global industrial use.
