Professional Applications & Engineering Value
This 1/4"-20 x 2" stainless steel rounded head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress demands. The 18-8 stainless steel material combined with a passivated finish provides exceptional resistance to rust and chemicals, making it suitable for outdoor, marine, and chemical processing equipment. The flanged and partially threaded design enhances stability and prevents over-tightening, while the hex drive ensures efficient installation in confined spaces. Ideal for machinery, automotive assemblies, and structural frameworks, this screw delivers long-term reliability and reduces maintenance costs in heavy-duty applications.
Specification Summary & Compliance
This screw features a UNC coarse thread with Class 3A fit for precision and strength, a minimum thread length of 1", and dimensions including a 0.563" flange diameter. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to environmental and safety regulations. Manufactured to high standards with Rockwell B70 hardness and 70,000 psi tensile strength, it guarantees consistent performance in demanding industrial settings.
