Professional Applications & Engineering Value

This 8-32 UNC thread shoulder screw is engineered to address critical alignment and pivot point requirements in precision assemblies. The 18-8 Stainless Steel material provides excellent resistance to oxidation and chemical exposure, making it suitable for machinery, automotive subsystems, and electronic enclosures operating in corrosive conditions. The hex socket drive and knurled head design allow for high-torque installation without slippage, ensuring consistent clamping force. The 3/16" shoulder length and tightly controlled tolerances enable exact component positioning, eliminating misalignment in rotating parts or bearing mounts. This combination of corrosion-resistant properties, high tensile strength, and precision fit reduces maintenance intervals and enhances the durability of industrial equipment.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit per UNC standards, ensuring high precision for critical assemblies. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for accurate positioning. It is manufactured from 18-8 Stainless Steel with a hardness of Rockwell B55 and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use.
