Professional Applications & Engineering Value
This 316 stainless steel shoulder screw with 10-32 UNF fine thread is engineered to address common industrial challenges such as component misalignment, corrosion-induced failure, and vibration loosening. The Class 3A thread fit guarantees minimal backlash and secure fastening in precision equipment, while the knurled socket head enhances tool engagement for efficient assembly in confined spaces. Its high tensile and shear strength makes it suitable for rotating assemblies, machinery linkages, and pivoting joints where durability and corrosion resistance are critical. Ideal for use in automotive, aerospace, and marine applications, this screw provides reliable performance under stress and harsh conditions, reducing maintenance needs and downtime.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, featuring a Class 3A thread fit for precise dimensional accuracy and a UNF 10-32 fine thread with controlled spacing. The shoulder diameter (1/4") and length (1/8") maintain tight tolerances for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety standards for industrial use.
