The Urrea 12-point socket is made of high-quality steel, resulting in outstanding performance on the job. They feature a chrome-nickel finish to prevent corrosion. The 12 point design has the advantage of distributing better force around a larger area on the nut faces, more toward the center, not on the edges. The force is distributed on the socket´s lobes, allowing you to fit hexagonal and square nuts or screws faster, all this thanks to its Super drive geometry featuring a 30 degree recovery angle. Opening size: 19mm. length: 1-1/2".
