Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 1/4"-20 UNC Hex Head Screw in 316 Stainless Steel addresses critical challenges like corrosion in marine, chemical processing, and outdoor applications. The coarse thread spacing and Class 2A thread fit ensure rapid, secure fastening even in high-vibration settings, minimizing assembly time and maintenance. Its partial threading concentrates clamping force where needed, preventing joint loosening. With an external hex drive, it offers high torque capability for heavy-duty machinery, structural frameworks, and equipment requiring 70,000 psi tensile strength. This screw is a reliable solution for engineers prioritizing durability, regulatory adherence, and long-term performance in corrosive or high-stress conditions.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit for consistent dimensional accuracy under the ASME B18.2.1 standard. It features a 1/4"-20 UNC coarse thread with right-hand direction and partial threading up to a 2" length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and material restrictions are met for industrial use.
