Professional Applications & Engineering Value
This 1/4"-20 UNC coarse thread screw with a low truss head and slotted drive is engineered to address common industrial challenges such as vibration loosening and corrosion-induced failure. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to rust and chemicals, making it suitable for outdoor equipment, food processing machinery, and marine applications. Its rounded truss head offers a larger bearing surface, reducing the risk of surface damage while maintaining a low profile. With a tensile strength of 80,000 psi and full threading, it ensures durable, long-term fastening in assemblies requiring high shear and tensile loads, from heavy-duty enclosures to structural frameworks.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for standard tolerance and ease of assembly. It is fully threaded and measures 2" in length, with a head diameter of 0.755" and low-profile height. Manufactured from 18-8 stainless steel with a passivated finish, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
