Professional Applications & Engineering Value
This 1/4"-20 UNC Socket Head Cap Screw is engineered to address common industrial challenges such as corrosion-induced failure and assembly inefficiency. The 18-8 Stainless Steel material offers excellent resistance to rust and chemical exposure, making it suitable for outdoor equipment, marine applications, and food processing machinery. Its Class 3A thread fit and coarse UNC threading ensure tight, reliable connections that resist loosening under vibration, critical in automotive, aerospace, and heavy machinery. The vented screw feature allows for pressure release in pneumatic or hydraulic systems, preventing seal damage. With a hex drive design, it enables precise torque control, reducing the risk of strip-out and enhancing worker safety during high-torque applications.
Specification Summary & Compliance
This socket head cap screw adheres to UNC coarse thread standards with a Class 3A thread fit for precise dimensional accuracy. It is manufactured with a right-hand thread direction and is fully threaded for consistent engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
