Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to address critical alignment and durability challenges in precision machinery and industrial assemblies. The 18-8 stainless steel material provides excellent resistance to corrosion and oxidation, making it suitable for applications in moist or chemically exposed settings. The 1" shoulder length with controlled tolerances ensures accurate spacing and reduces stress on threaded sections, preventing misalignment in rotating components like gears, pulleys, and linkages. Combined with a hex socket head and knurled texture, it allows for easy installation in confined spaces while maintaining torque integrity. Its fine UNF threads and Class 2A fit offer secure fastening under dynamic loads, minimizing loosening in high-vibration environments such as automotive, aerospace, and automation systems.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit for consistent engagement and meets UNF fine thread standards. Dimensions include a 3/16" thread length, 1" shoulder length (tolerance: -0.005" to 0.005"), and 3/16" shoulder diameter (tolerance: -0.004" to -0.002"). It is manufactured from 18-8 stainless steel with a hardness of Rockwell B55 and tensile strength of 70,000 psi. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
