Description
The 1/4"-20 Socket Head Cap Screw is a precision-engineered, high-strength fastener commonly used in machinery, automotive, aerospace, and tooling applications where clean appearance and tight clearances are important. Designed with a cylindrical head and a recessed hex drive, this screw allows for reliable torque application using an Allen (hex) wrench and is ideal for applications requiring a flush or recessed fit.
