Professional Applications & Engineering Value

This 316 stainless steel shoulder screw delivers exceptional engineering value in precision assembly applications where corrosion resistance and dimensional accuracy are critical. The UNC coarse thread with Class 3A fit provides superior vibration resistance in rotating machinery, pivot points, and precision alignment systems. The knurled socket head with hex drive ensures secure tool engagement during installation, preventing slippage in high-torque applications. Engineered to withstand demanding conditions, these shoulder screws maintain their structural integrity in chemical processing, marine environments, and food processing equipment where 316 stainless steel's enhanced corrosion resistance is essential. The precisely machined shoulder provides accurate spacing and alignment for gears, bearings, and other rotating components.

Specification Summary & Compliance

Manufactured to exacting standards with Class 3A thread fit precision and UNC 10-24 coarse threading. The shoulder diameter maintains tight tolerance of -0.004" to -0.002" with shoulder length tolerance of -0.005" to 0.005". Compliant with ASME B18.3 specifications for dimensional consistency and interchangeability. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, ensuring safe use across global industrial markets.
