• Compliance with industry standards including ASME B18.3, RoHS, and REACH for guaranteed quality and safety

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address critical challenges in precision machinery and industrial equipment. The 316 Stainless Steel material provides excellent resistance to corrosion and oxidation, making it suitable for marine, chemical processing, and food-grade environments. The Black Oxide finish not only enhances aesthetics but also reduces friction and prevents seizing during repeated use. With a Class 3A thread fit and precise shoulder dimensions, it ensures accurate alignment in assemblies, minimizing misalignment and wear in applications like rotating shafts, bearings, and linkages. The socket head design with a 1/8" hex drive allows for easy access in confined spaces, streamlining installation and maintenance workflows while maintaining high tensile and shear strength for reliable performance under load.

Specification Summary & Compliance

This shoulder screw adheres to strict dimensional tolerances, including a Class 3A thread fit for high-precision assemblies and standard UNC threading. The shoulder diameter and length are manufactured to precise specifications (e.g., shoulder diameter tolerance of -0.004" to -0.002"). It complies with ASME B18.3 standards for consistency and reliability, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are upheld.
