Professional Applications & Engineering Value
This 10-32 UNF Class 3A rounded head screw is engineered to solve critical challenges in industries where corrosion, vibration, and high stress are common. Made from 316 stainless steel with a passivated finish, it resists chemicals, saltwater, and oxidation, making it ideal for marine, pharmaceutical, and food processing equipment. The fine thread spacing and Class 3A thread fit provide tight tolerances that prevent loosening under dynamic loads, while the fully threaded design ensures consistent clamping force. The rounded button head and 1/8" hex drive allow for flush, tool-friendly installation in confined spaces, reducing assembly time and improving safety in industrial screw applications.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications, with a Class 3A thread fit for precision and a UNF thread type (10-32) with fine spacing. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met. Dimensions include a 2" length, 0.19" thread diameter, and 0.361" head diameter, all manufactured to consistent quality for reliable stainless steel fastener performance.
