Professional Applications & Engineering Value
This 316 stainless steel rounded button head screw with 10-24 UNC coarse threading is engineered for demanding industrial applications where corrosion resistance and mechanical reliability are critical. The passivated finish enhances its ability to withstand aggressive environments, such as marine, chemical processing, and food equipment, preventing premature failure. Its flanged design provides a larger bearing surface, reducing surface pressure and minimizing loosening under vibration. The hex drive allows for high-torque installation, ensuring tight, secure fastening in assemblies requiring repeated maintenance. Fully threaded for maximum grip, this screw delivers consistent performance in high-strength, corrosion-resistant fastening scenarios, from machinery to structural components.
Specification Summary & Compliance
This screw features a 10-24 UNC coarse thread with Class 3A fit for precise tolerance, ensuring reliable thread engagement. Dimensions include a 3/8" length, 0.406" flange diameter, and fully threaded design. Manufactured from 316 stainless steel with a passivated finish, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for regulated industries and environmental safety standards.
