3/8″ Drive x 1/4″ Square Female Pipe Plug Socket

3/8″ Drive x 1/4″ Square Female Pipe Plug 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.
