Professional Applications & Engineering Value
This 2-56 UNC shoulder screw in 316 stainless steel addresses critical needs in precision machinery, automotive, and electronic assemblies where alignment accuracy and corrosion resistance are paramount. The passivated finish enhances durability against chemical exposure and oxidation, extending service life in demanding conditions. Its precise shoulder diameter (3/32") and length (1/16") with controlled tolerances prevent component misalignment, reducing wear and maintenance costs. The socket head hex drive ensures high torque transmission without slippage, making it suitable for confined spaces in industrial equipment and robotics. Engineered for right-hand coarse threads, it provides rapid installation while maintaining 70,000 psi tensile strength for high-stress applications.
Specification Summary & Compliance
Manufactured to Class 2A thread fit and inch system standards, this shoulder screw features UNC coarse threading with 2-56 size and 1/8" thread length. Shoulder dimensions include 3/32" diameter (-0.001" to 0" tolerance) and 1/16" length (0" to 0.002" tolerance) for precise assembly. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements for industrial fasteners.
