Professional Applications & Engineering Value
This alloy steel shoulder screw with 10-24 UNC coarse thread and black oxide finish is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty equipment. The 3/8" shoulder length and 1/4" shoulder diameter provide accurate alignment and spacing in assemblies, reducing wear on moving parts. The coarse thread and Class 3A fit enable quick, secure fastening even in high-vibration environments, while the knurled socket head ensures tool grip integrity during repeated maintenance. Ideal for use in robotics, conveyor systems, and industrial jigs, this screw delivers reliable performance where dimensional accuracy and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, with precise Class 3A thread fit and shoulder tolerances (diameter: -0.004" to -0.002"; length: -0.005" to 0.005"). Threads are 10-24 UNC coarse, right-hand style, and the screw meets ASTM A574 material standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications.
