Proto® Socket Bit Set, SAE, 3/8 in Drive, 12 Pieces, Full Polished
- Internal design minimizes fastener rounding, helps to extend fastener life, and allows the user to more easily turn worn, rounded, or rusted fasteners
- Design is a high performance drive configuration which allows for quick and easy socket engagement to the fastener flats, not the corners
- Configuration employs a radius corner design, shifting contact area and stress away from the fastener corners and distributing contact stresses over a large area of the socket, minimizing slippage
