Socket Sets
Proto socket sets are suitable for use with damaged and stubborn fasteners, as well as those made of soft materials, like aluminium, lead and tin. These Proto impact sockets feature a TorquePlus configuration featuring a radius-corner design for shifting the stresses away from the corners and uniformly distributing over a large surface area. The internal design of these sockets further reduces rounding of the edges and offers more flexibility to turn worn out or rusted fasteners. These Proto tool socket sets are available in 1/4, 3/8 and 1/2 inch drive sizes having chrome, full polished or black oxide finishes on Raptor Supplies.
