Proto 1 inch drive SAE sockets are used on stubborn or damaged or on fasteners made from soft materials. Their patented TorquePlus design provides high-performance drive configuration for quick and easy socket engagement to the fastener flats. These sockets have an internal design which reduces fastener rounding, improves fastener life and allows the user to easily turn worn, rounded or rusted fasteners. The TorquePlus configuration makes use of a radius-corner design for shifting contact area & stress away from the fastener corners and distributing contact stresses over a large area of the socket, reducing slippage. Choose from a broad range of Proto 1 inch drive SAE sockets available in chrome and satin finishes on Raptor Supplies.
