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 reliable, high-strength fastening. The brass material inherently resists rust and galvanic corrosion, making it perfect for marine, electrical, and plumbing systems where exposure to elements is a concern. With a Class 3A thread fit and coarse UNC thread type, it ensures tight, secure connections that minimize backlash and maintain integrity in high-vibration environments like machinery and automotive assemblies. The standard hex socket head design facilitates easy access in confined spaces, reducing installation time and improving maintenance efficiency. Fully threaded and right-hand oriented, this screw delivers consistent performance in industrial applications requiring durability and compliance with stringent standards.
