The Mac Tools Precision Torque Hand and Impact Sockets won’t slip on fasteners rounded up to 85 percent, according to the company. The inner geometry of the six-point socket holds nuts and bolts even when they get rounded. Each hand socket is made of chrome vanadium steel and each impact socket is made of chromoly steel to hold up to a lifetime of use. All sets come with a clip rail system, which hold the sockets snug when not in use and allows the user to rotate the socket 360 degrees. This line includes chrome and impact sets featured in 1/4", 3/8" and 1/2" drives.
