Professional Applications & Engineering Value
This 1/4-20 UNC Rounded Truss Head Slotted Screw is engineered to address common industrial challenges, such as corrosion-induced failure and uneven load stress. Constructed from 18-8 Stainless Steel with a passivated finish, it resists rust and chemical exposure, making it ideal for outdoor equipment, marine hardware, and food processing machinery. The wide truss head distributes clamping force over a larger area, minimizing the risk of surface cracking in softer materials. With a coarse thread and Class 2A fit, it ensures quick assembly and reliable performance in high-vibration settings like automotive assemblies or structural frameworks, providing a durable, corrosion-resistant fastening solution that meets rigorous industry demands.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A tolerance for precise fit and ease of use. It is manufactured in accordance with ASME B18.6.3 specifications, ensuring dimensional accuracy and reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental safety and restricted substance control.
