3/8" Drive x 12mm 12 Point Standard GRE1112M Grey Pneumatic

3/8" Drive x 12mm Standard Length 12-Point Impact Socket.  Our impact sockets grip the fastener across a broader contact area, reducing chance of rounding off fasteners.  They also allow up to 20% more torque to be applied than on other impact sockets.  The shift in pressure allows us to reduce the socket wall thickness, increasing access to tight areas.
