Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. The 18-8 Stainless Steel material offers excellent corrosion resistance, making it suitable for machinery, automotive, and electronics applications where exposure to moisture or chemicals is common. The low profile socket head and precise shoulder dimensions ensure minimal space usage while maintaining exact component positioning, reducing wear and misalignment. With a coarse thread and Class 2A fit, it facilitates quick assembly and disassembly, enhancing productivity in high-volume production lines. Its robust 70,000 psi tensile strength and Rockwell B55 hardness provide long-term reliability, minimizing downtime and maintenance costs for B2B clients.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a shoulder diameter of 3/16" (tolerance: -0.001" to 0") and shoulder length of 1/4" (tolerance: 0" to 0.002"), ensuring precise assembly. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmental safety and regulatory requirements in global industrial markets.
