Professional Applications & Engineering Value
This 10-32 UNF shoulder screw delivers critical engineering value in precision assemblies where exact alignment is paramount. The 2" shoulder length with precise diameter control provides stable bearing surfaces for rotating components in machinery, automation systems, and optical devices. Manufactured from 18-8 stainless steel with TiCN coating, it solves common industrial challenges including corrosion in humid environments and wear from repeated adjustments. The Class 2A thread fit ensures consistent clamping force in applications subject to vibration, while the fine UNF threads offer superior load distribution compared to coarse thread alternatives. These features make it particularly valuable in precision manufacturing, medical equipment, and aerospace components where reliability and dimensional accuracy are non-negotiable.
Specification Summary & Compliance
This shoulder screw maintains Class 2A thread fit per UNF standards with precise shoulder diameter tolerance of -0.002" to 0". The product conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring adherence to international environmental regulations. Manufacturing specifications include Rockwell B55 hardness and 70,000 psi tensile strength for consistent mechanical performance across industrial applications.
