Professional Applications & Engineering Value
This 10-24 UNC shoulder screw delivers critical engineering solutions for precision machinery and industrial equipment. The alloy steel construction with Rockwell C32 hardness provides exceptional durability against wear and fatigue in high-cycle applications. The black oxide finish offers reliable corrosion protection while maintaining dimensional stability. With its 3/8" thread length and 1/4" shoulder diameter, this component ensures precise component alignment in assemblies requiring accurate axial positioning. The UNC coarse threads combined with Class 3A thread fit guarantee secure fastening in vibrating environments, making it ideal for robotics, automation systems, and precision manufacturing equipment where shoulder screws must maintain consistent positioning under dynamic loads.
Specification Summary & Compliance
This shoulder screw features precision dimensions including Class 3A thread fit for superior engagement, UNC thread standards for compatibility, and shoulder diameter tolerance of -0.004" to -0.002" for exact alignment. Manufacturing complies with ASME B18.3 specifications where identified as ASTM A574. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental and safety standards for industrial applications.
