Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers exceptional engineering value in precision assembly applications where corrosion resistance and mechanical reliability are critical. The Class 3A thread fit ensures secure fastening in machinery, automation systems, and industrial equipment, while the knurled socket head provides superior torque transmission without slippage. The UNC coarse threads facilitate rapid installation in production environments, and the generous 2 1/8" shoulder length accommodates multiple component layers with precise spacing. Engineered to withstand demanding conditions, these shoulder screws maintain dimensional integrity under load, making them ideal for pivoting mechanisms, rotating assemblies, and precision guiding systems where alignment accuracy is paramount.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNC thread specifications. Shoulder diameter tolerance maintained at -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005" for precision applications. Fully compliant with ASME B18.3 manufacturing specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Material hardness rated at Rockwell B79 with mechanical properties verified to industry standards.
