Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to solve critical alignment and load-bearing challenges in precision machinery. The 17-4 PH Stainless Steel construction provides excellent corrosion resistance, making it suitable for aerospace, medical devices, and automation equipment where exposure to moisture or chemicals is common. The Class 3A thread fit and 3/16" shoulder diameter ensure precise positioning of moving parts, reducing play and minimizing wear in high-cycle applications. The hex socket drive with knurled head allows for secure torque application in confined spaces, while the 130,000 psi tensile strength handles dynamic loads without failure. Ideal for robotics, fixturing, and precision instrument assemblies where reliability and dimensional accuracy are paramount.
Specification Summary & Compliance
