Proto 3/4" Female X 1/2" Male Black Oxide Impact Adapter

This specially heat treated socket adapter is for electric or air powered drive tools. This tool features a radius corner design which causes the socket to grab the sturdy wall, or flat, of the fastener instead of grabbing the corners, resulting in less corner wear on the fastener.
