Professional Applications & Engineering Value
This 18-8 stainless steel shoulder screw is engineered to address critical challenges in machinery and equipment assembly. The 2" precision shoulder provides a stable bearing surface for rotating parts like pulleys and gears, minimizing friction and alignment issues. With a coarse UNC thread and Class 2A fit, it offers rapid installation and robust holding power in industrial applications such as automotive fixtures, conveyor systems, and robotic arms. The hex socket head with knurling allows for easy access in confined spaces, while the high tensile and shear strength ensures reliability under dynamic loads, reducing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent precision. Dimensions include a 0.75" thread diameter, 7/8" thread length, and shoulder diameter tolerance of -0.004" to -0.002". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material quality for industrial use.
