Professional Applications & Engineering Value
This shoulder screw is engineered to address critical alignment and wear challenges in industrial applications. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to rust and chemical exposure, extending service life in demanding settings like machinery, automotive assemblies, and conveyor systems. The 1-1/2" shoulder length and precise 5/8" shoulder diameter allow for exact component positioning, reducing misalignment and friction. With a Class 3A thread fit and UNC coarse thread, it ensures quick, secure fastening even in high-vibration environments, minimizing maintenance needs and enhancing operational reliability for B2B clients.
Specification Summary & Compliance
This shoulder screw features a 1/2"-13 UNC coarse thread with Class 3A thread fit for high precision, along with a shoulder diameter tolerance of -0.001" to 0.001" and shoulder length tolerance of -0.005" to 0.005". It complies with ASME B18.3 manufacturing standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and quality assurance for industrial use.
