Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and strength challenges in precision machinery, automation systems, and electronic assemblies. The 18-8 stainless steel material, combined with a black oxide finish, provides excellent resistance to corrosion and oxidation, extending component life in demanding conditions. The 3/16" shoulder length with minimal tolerance variation ensures accurate positioning of moving parts, such as gears and pulleys, reducing misalignment and wear. Its Class 3A thread fit and coarse thread spacing facilitate quick, secure fastening, minimizing the risk of loosening under vibration. Ideal for use in robotics, conveyor systems, and medical devices, this screw delivers reliable performance where precision and durability are paramount.
Specification Summary & Compliance
The screw features a Class 3A thread fit with UNC coarse threads, ensuring tight tolerances for secure fastening. Shoulder dimensions include a diameter of 3/16" (tolerance: -0.004" to -0.002") and length of 1/2" (tolerance: -0.005" to 0.005"), providing precise engineering alignment. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial and electronic applications without hazardous substances.
