Professional Applications & Engineering Value
This 10-24 UNC shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and assembly jigs. The 316 Stainless Steel material provides excellent resistance to chemicals and moisture, reducing failure risks in corrosive settings like marine or chemical processing equipment. The Black Oxide finish minimizes friction and wear, while the hex socket head allows for efficient torque transmission in tight spaces. The shoulder diameter and Class 3A thread fit ensure precise component alignment and secure retention, preventing misalignment and loosening under dynamic loads. Ideal for pivots, axles, and spacers, this screw enhances operational reliability and reduces maintenance needs in industrial applications.
Specification Summary & Compliance
This shoulder screw features a 10-24 UNC coarse thread with Class 3A precision tolerance for secure fastening. Key dimensions include a 3/8" shoulder diameter (tolerance: -0.004" to -0.002") and 3/8" thread length. It meets ASME B18.3 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international safety and environmental standards.
