Description
The 1/2"-13 Socket Head Cap Screw is a robust, precision-engineered fastener commonly used in heavy machinery, automotive, aerospace, and structural tooling applications where high strength and tight clearances are critical. Featuring a cylindrical head with a recessed hex drive, this screw allows for secure torque application using an Allen (hex) wrench, making it ideal for installations requiring a flush or recessed fit without compromising strength.
