Professional Applications & Engineering Value
This 1/4"-20 UNC brass socket head cap screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and the need for high-strength, non-magnetic fasteners. The brass material offers excellent resistance to rust and galvanic corrosion, making it suitable for marine, electrical, and plumbing systems. The coarse thread design and Class 3A thread fit ensure a tight, reliable connection that withstands dynamic loads and thermal cycling. With a 50,000 psi tensile strength and Rockwell B55 hardness, it provides durable performance in machinery, automotive assemblies, and precision equipment where corrosion resistance and mechanical integrity are critical. The hex drive allows for high-torque installation, reducing the risk of stripping and improving maintenance efficiency.
Specification Summary & Compliance
This screw adheres to UNC (Unified Coarse) thread standards with a Class 3A thread fit for precise dimensional accuracy. It features a 1/4"-20 thread size, 1/2" length, and fully threaded design. Manufactured from brass with a standard socket head profile and 3/16" hex drive, it complies with REACH (EC 1907/2006) regulations, ensuring the absence of hazardous substances and supporting sustainable industrial practices.
