Professional Applications & Engineering Value
This 2-56 UNC shoulder screw is engineered to address critical challenges in precision machinery, electronics, and automotive systems. The 18-8 Stainless Steel material provides excellent corrosion resistance, reducing maintenance in humid or corrosive settings. Its Class 3A thread fit and coarse UNC thread ensure quick assembly and high vibration resistance, preventing loosening in dynamic applications. The knurled socket head with a 5/64" hex drive allows for secure tool engagement, minimizing stripping and enhancing torque transmission. Ideal for pivots, spacers, and rotating assemblies, this screw offers reliable performance where alignment and strength are paramount, supported by its robust tensile and shear strength.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. Key specifications include a shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005", ensuring consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental responsibility in industrial use.
