Professional Applications & Engineering Value
Engineered for demanding environments, these 1/4-28 UNF rounded truss head screws in 316 stainless steel address critical challenges like corrosion, vibration loosening, and assembly reliability. The passivated finish enhances surface durability against chemicals and moisture, making them ideal for marine, chemical processing, and food equipment applications. The wide truss head provides a larger bearing surface, reducing the risk of material damage in softer substrates while improving clamp load distribution. With fine UNF threads and Class 2A fit, they ensure tight, precise fastening in machinery, enclosures, and structural components where high tensile strength and long-term performance are non-negotiable.
Specification Summary & Compliance
This screw features a 1/4"-28 UNF fine thread with Class 2A tolerance for precise fit, fully threaded along a 1" length. It complies with ASME B18.6.3 manufacturing standards and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and regulatory adherence for industrial use.
