Professional Applications & Engineering Value
This 1/4"-20 UNC Socket Head Cap Screw is engineered to solve critical challenges in industrial fastening. The 18-8 Stainless Steel material provides excellent resistance to oxidation and corrosion, making it suitable for applications in food processing, marine, and chemical equipment where moisture is a concern. The Class 3A thread fit and coarse UNC thread ensure rapid assembly and high vibration resistance, reducing maintenance needs in machinery and structural frameworks. The vented feature is particularly valuable in pneumatic or hydraulic systems, preventing pressure build-up and potential component damage. Its partially threaded design allows for secure clamping where full thread engagement is not required, offering versatility in precision engineering projects.
Specification Summary & Compliance
This screw adheres to the Unified Coarse (UNC) thread standard with a Class 3A thread fit for high precision. Dimensions include a 1/4"-20 thread size, 1 1/2" length, and a 3/16" hex drive. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substances.
