• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use
• Optimized for automated assembly with consistent right-hand coarse threading and standard socket head profile

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw delivers critical engineering value in precision assemblies where alignment and rotational control are paramount. Manufactured from 18-8 Stainless Steel, it resists corrosion in manufacturing, automotive, and electronics environments. The Class 3A thread fit and coarse UNC threading ensure rapid installation and vibration resistance, while the knurled socket head provides superior torque transmission. The precisely machined shoulder acts as a bearing surface or pivot point, eliminating the need for additional spacers in machinery, conveyor systems, and robotic arms. Its 70,000 psi tensile strength supports high-stress applications, making it a reliable choice for OEMs requiring durability and dimensional accuracy.

Specification Summary & Compliance

This shoulder screw features a Class 3A thread fit with UNC coarse threads (8-32), ensuring precise engagement and interchangeability. The shoulder diameter is maintained at 3/16" with a tolerance of -0.004" to -0.002", and the shoulder length is 3/16" with a tolerance of -0.005" to 0.005" for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for restricted substance-controlled industries. Manufactured to standard industrial specifications for socket head shoulder screws, it guarantees reliability in automated and manual assembly processes.
