Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. The 316 Stainless Steel construction, combined with a passivated finish, provides exceptional resistance to corrosion, making it suitable for applications in chemical processing, marine equipment, and food machinery where moisture and corrosive agents are present. The 10-32 UNF fine thread and Class 2A fit ensure tight tolerances and secure fastening, reducing the risk of loosening under vibration—common in automotive and aerospace assemblies. The precisely machined shoulder acts as a pivot or spacer, facilitating accurate component positioning in robotics, conveyor systems, and precision instruments, thereby minimizing wear and improving overall system reliability. This screw’s high tensile strength and hex socket drive further support efficient installation in confined spaces, enhancing productivity for B2B technical buyers.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit and UNF thread standards, ensuring dimensional accuracy for the 10-32 thread size with a fine pitch. Shoulder dimensions include a diameter of 1/4" (tolerance: -0.001" to 0") and length of 5/16" (tolerance: 0" to 0.002"), providing precise fit for engineering applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use without hazardous substances.
