Professional Applications & Engineering Value
This alloy steel shoulder screw with 5/16"-24 UNF fine thread delivers critical engineering solutions for precision machinery and industrial equipment. The black oxide finish provides essential corrosion protection in manufacturing environments where exposure to moisture and chemicals is common. The Class 3A thread fit ensures vibration resistance and maintains clamping force in dynamic applications, while the precisely machined shoulder with tight tolerances enables accurate alignment of moving components in assemblies, reducing wear and extending equipment lifespan. The combination of 140,000 psi tensile strength and Rockwell C32 hardness makes these shoulder screws ideal for high-stress applications in automation systems, machinery mounts, and precision rotating assemblies where reliability is paramount.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit and UNF thread specifications. Shoulder diameter tolerance maintained at -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005". Compliant with RoHS 3 (2015/863/EU) with exemption 6(a) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial applications.
