Professional Applications & Engineering Value
This 5/8"-11 UNC shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial machinery, automated systems, and precision equipment. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, while the black oxide finish reduces friction and wear during operation. The 3 1/2" precision shoulder ensures accurate positioning of moving parts, minimizing vibration and misalignment in high-stress environments. With a knurled head and hex drive, it allows for secure installation without slippage, enhancing assembly efficiency. Ideal for applications requiring robust shear strength and reliable performance, this shoulder screw delivers long-term value in heavy-duty settings.
Specification Summary & Compliance
This shoulder screw features a Class 2A thread fit with UNC coarse threading for reliable engagement. The shoulder diameter tolerance is -0.004" to -0.002", and the shoulder length tolerance is -0.005" to 0.005", ensuring high dimensional accuracy. Manufactured from 18-8 stainless steel with a black oxide finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, supporting environmentally responsible and safe industrial use.
