Professional Applications & Engineering Value
This precision 8-32 UNC shoulder screw solves critical alignment challenges in industrial machinery, automation systems, and precision instruments. The 18-8 Stainless Steel construction provides excellent corrosion resistance while maintaining Rockwell B55 hardness for long-term reliability. The low profile socket head design allows for compact assembly in space-constrained applications, while the precisely machined shoulder ensures accurate component positioning and rotational stability. With 70,000 psi tensile strength and Class 2A thread fit, these shoulder screws maintain structural integrity under dynamic loads and vibration, making them ideal for manufacturing equipment, robotic arms, and precision mechanical assemblies where dimensional accuracy and durability are paramount.
Specification Summary & Compliance
This shoulder screw features 8-32 UNC coarse threads with Class 2A thread fit for standard industrial compatibility. The precision shoulder maintains 3/16" diameter (-0.001" to 0" tolerance) and 3/16" length (0" to 0.002" tolerance) for exact component alignment. Manufactured from 18-8 Stainless Steel with Rockwell B55 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial applications.
