• Consistent quality and reliability backed by compliance with ASME B18.3, RoHS 3, and REACH standards
• Optimized for fine-thread applications using 10-32 UNF right-hand threads to prevent loosening under vibration

Professional Applications & Engineering Value

This 10-32 UNF thread shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and mechanical failure. The 316 stainless steel material provides excellent resistance to corrosive elements, making it suitable for marine, chemical processing, and outdoor equipment. The black oxide finish not only enhances corrosion protection but also reduces friction during installation. With a Class 3A thread fit and fine threading, it ensures secure fastening in high-vibration environments like machinery, automotive assemblies, and precision instruments. The knurled socket head allows for easy handling and torque application, reducing installation errors and improving workflow efficiency in B2B settings where reliability and compliance with ASME B18.3 are critical.

Specification Summary & Compliance

This shoulder screw features precise dimensions, including a thread size of 10-32 UNF with Class 3A thread fit for high accuracy, and tolerances such as shoulder diameter of -0.004" to -0.002". It meets ASME B18.3 specifications for consistent manufacturing quality, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory adherence in industrial applications.
