Professional Applications & Engineering Value
This 1/4"-20 UNC Socket Head Cap Screw is engineered to solve critical challenges in industrial assembly and precision machinery. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications exposed to moisture, chemicals, or outdoor elements. The coarse UNC thread and Class 3A fit enable faster installation and a more secure, vibration-resistant connection compared to finer threads, reducing assembly time and maintenance needs. The high-profile socket head and square drive allow for high torque application with minimal risk of cam-out, ensuring a tight, reliable fastening in high-strength applications from automotive to heavy equipment manufacturing.
Specification Summary & Compliance
This fastener adheres to UNC coarse thread standards with a precise Class 3A thread fit for superior dimensional accuracy. The manufacturing specifications include a 1/4"-20 thread size, 7/8" length, and a fully threaded design. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets the latest environmental and safety standards for industrial components.
