The Urrea 12-point socket line 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 to the scocket ́s lobes, allowing you to fit hexagonal, square nuts or screws faster, all this thanks to its Super Drive geometry, featuring a 30 degree recovery angle. Opening size: 9/16”. Length: 1-1/2". Nut end outside diameter: 13/16". Drive end outside diameter: 7/8". Nut depth: 1/2".
