Professional Applications & Engineering Value
This alloy steel shoulder screw is engineered to address critical alignment and positioning challenges in precision machinery. The Class 3A UNF fine thread offers superior thread engagement, minimizing the risk of loosening in vibrating equipment, while the black oxide finish provides a durable barrier against rust and wear in humid or corrosive settings. With a knurled socket head and hex drive, it ensures easy torque application without stripping, making it ideal for automated assembly lines. The precisely machined shoulder maintains consistent spacing in mechanical assemblies, such as rotating shafts and linkages, reducing downtime and enhancing operational reliability in industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit for high-precision UNF fine threads, with shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005" ensuring exact dimensional control. Manufactured in accordance with standard inch system specifications, it complies with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006), confirming environmental safety and regulatory adherence for industrial use.
