Professional Applications & Engineering Value
This 12-24 UNC coarse thread rounded truss head screw is engineered to address common industrial challenges such as material fatigue, corrosion, and assembly efficiency. The passivated 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, marine hardware, and food processing machinery. The wide truss head distributes clamping force effectively, preventing pull-through in softer materials like plastics or sheet metal. With its fully threaded design and coarse thread, it ensures rapid installation and robust fastening in applications requiring high vibration resistance, such as automotive assemblies, electrical enclosures, and structural frameworks. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures durability under dynamic loads, reducing maintenance needs and downtime.
Specification Summary & Compliance
This screw features a 12-24 UNC coarse thread with a Class 2A thread fit, ensuring precise dimensional accuracy and reliable performance. It is manufactured in compliance with ASME B18.6.3 specifications, guaranteeing consistency and interchangeability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety standards for use in various industrial and consumer applications.
