Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 316 stainless steel rounded truss head screws address critical challenges in corrosive and high-stress environments. The combination of UNF fine threading and Class 2A thread fit ensures tight, secure fastening that resists loosening under vibration, making them ideal for machinery, marine equipment, and chemical processing systems. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, providing an extra layer of protection against acids, salts, and moisture. With a Rockwell B100 hardness and 100,000 psi tensile strength, these fully threaded screws deliver consistent performance in structural assemblies, panel fastening, and equipment where reliability and longevity are paramount.
Specification Summary & Compliance
This 1/4"-28 UNF fine thread screw features a Class 2A thread fit for precision and interchangeability, manufactured in accordance with ASME B18.6.3 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. The screw is made from 316 stainless steel with a passivated finish, providing optimal corrosion resistance and durability for industrial use.
