Professional Applications & Engineering Value
This 10-32 UNF Class 3A threaded 316 Stainless Steel rounded head screw is engineered to address critical challenges in industrial settings, such as vibration loosening and corrosive degradation. The fine thread spacing and Class 3A fit ensure tight tolerances and superior fatigue resistance, making it ideal for precision assemblies in machinery, marine equipment, and chemical processing plants. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, prolonging service life in saline or acidic conditions. Combined with a hex drive and flanged button head, it offers easy installation with standard tools while distributing clamp load effectively, reducing the risk of surface damage and maintaining joint integrity under high stress.
Specification Summary & Compliance
This screw adheres to UNF thread standards with a Class 3A fit for high precision and strength. Key dimensions include a 10-32 thread size, 5/8" length, and 0.406" flange diameter. It is fully threaded and features a right-hand thread direction. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial applications.
