Impact Hex Bit Socket Set, 3/8" Drive, 7 Piece, 4mm to 12mm, 4" Long, in Blow Molded Case. 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.
