Professional Applications & Engineering Value
This 316 stainless steel rounded truss head screw delivers critical performance in demanding industrial settings where corrosion and mechanical integrity are paramount. The UNF fine threading and Class 2A fit provide exceptional clamping force and vibration resistance, making it ideal for precision assemblies in machinery, marine hardware, and chemical processing equipment. The wide truss head distributes load over a larger area, protecting sensitive surfaces from indentation. With a passivated finish, the screw offers extended service life in humid or corrosive atmospheres, while the fully threaded design ensures consistent holding power across the entire fastener length, simplifying installation in tight spaces and reducing the need for multiple screw types.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications, this screw guarantees dimensional accuracy and interchangeability. Threads conform to UNF 1/4"-28 with Class 2A tolerance for precise fit. The screw meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances. Material properties include Rockwell B100 hardness and 100,000 psi tensile strength, validating its use in high-stress industrial applications.
