Professional Applications & Engineering Value
This socket head shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in machinery. The 5/16"-18 UNC coarse thread and Class 3A fit provide robust fastening with minimal loosening under vibration, while the 3/8" shoulder diameter offers precise bearing surfaces for pivots, gears, and linkages. Made from 18-8 Stainless Steel, it resists corrosion in moist or chemical environments, extending service life. The knurled head and hex drive enhance installation efficiency, making it ideal for assembly lines and maintenance in automotive, aerospace, and manufacturing sectors where reliability and compliance with ASME B18.3 are critical.
Specification Summary & Compliance
This shoulder screw adheres to tight dimensional tolerances, including a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005", ensuring precision in inch system applications. It conforms to ASME B18.3 standards for consistency and safety, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material reliability.
