Professional Applications & Engineering Value

This 6-32 UNC shoulder screw with nylon patch thread locker is engineered to address critical challenges in precision assemblies. The 18-8 Stainless Steel construction provides excellent resistance to corrosion and oxidation, making it suitable for medical devices, food processing equipment, and outdoor machinery. The Class 2A thread fit and precisely machined shoulder (with diameter tolerance of -0.001" to 0") ensure minimal radial play, which is vital for aligning gears, bearings, or linkages in automated systems. The integrated thread locking technology prevents loosening under vibration, reducing maintenance downtime and enhancing operational safety in robotics, conveyor systems, and automotive components. Its socket head design allows for compact installation in confined spaces, offering both reliability and ease of service.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent engagement. The shoulder features a precise diameter of 5/32" and length of 1/2" with tight tolerances (length tolerance 0" to 0.002") to ensure accurate positioning. Manufactured from 18-8 Stainless Steel with a hardness of Rockwell B55 and tensile strength of 70,000 psi, it meets rigorous mechanical demands. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for environmentally conscious and regulated industries.
