Professional Applications & Engineering Value

This 1-64 UNC thread shoulder screw delivers critical engineering value in precision assemblies requiring exact component positioning. The 18-8 stainless steel material provides excellent corrosion resistance for machinery in humid or chemically aggressive settings, while the Rockwell B55 hardness ensures long-term wear resistance. The knurled socket head combined with the 5/64" hex drive prevents tool slippage during high-torque installation, reducing assembly errors. Its Class 3A thread fit and coarse UNC thread design maintain clamping force under vibration, making it ideal for precision instruments, rotating shafts, and pivoting mechanisms where alignment accuracy and durability are paramount.

Specification Summary & Compliance

This shoulder screw features a 1-64 UNC coarse thread with Class 3A fit for high precision, a shoulder diameter of 3/32" with tight tolerance control, and shoulder length options from 0.13" to 1.99". Manufactured to exact standards, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial applications.
