Professional Applications & Engineering Value
This 1/4"-20 x 2" hex head screw delivers exceptional engineering value for demanding industrial applications where corrosion resistance and vibration management are critical. The 18-8 stainless steel composition provides superior protection against rust and chemical exposure, making it ideal for outdoor equipment, marine environments, and chemical processing facilities. The UNC coarse threading ensures rapid installation and reliable performance in softer materials or where frequent disassembly is required. With serrated locking features beneath the flanged head, this fastener maintains critical clamp force in high-vibration machinery, automotive assemblies, and structural frameworks. The combination of 100,000 psi tensile strength and Rockwell B100 hardness ensures durability in heavy-duty applications while the fully threaded design provides maximum engagement strength throughout the entire 2" length.
Specification Summary & Compliance
This flanged hex head screw features precise 1/4"-20 UNC coarse threading with Class 2A thread fit for consistent engagement and reliable performance. The fastener meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) standards, ensuring environmental responsibility in industrial applications. Manufacturing specifications include right-hand thread direction, external hex drive with 3/8" head width, and 9/16" flange diameter for optimal load distribution.
