Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers exceptional engineering value in precision mechanical systems where alignment accuracy and corrosion resistance are critical. The 10-32 UNF fine thread with Class 3A fit provides superior engagement in tapped holes, eliminating play in high-vibration environments. The extended 1-1/2" shoulder length serves as a precise pivot point or spacer in rotating assemblies, while the knurled socket head ensures reliable torque application during installation. Particularly valuable in machinery, automation equipment, and precision instruments, this shoulder screw's Rockwell B79 hardness and 70,000 psi tensile strength withstand repeated operational stresses while maintaining dimensional stability.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit precision and ASME B18.3 dimensional specifications. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005". Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Thread specifications conform to UNF fine thread standards with 10-32 sizing and right-hand thread direction.
