Wright Tool 1/2 in. and 3/4 in. Drive Socket Sets Wright Tool 1/2 in. and 3/4 in. drive socket sets are the right choice for long-lasting reliability， durability， and performance. Forged from domestic steel， most are polished and finished with a nickel chrome finish. They are available in a variety of styles including 6-point， 12-point， short or deep well， and spark plug. Patented 12-point Wright Drive tools give you 10 times more fastener contact area than conventional sockets. The patented 6-point Wright Drive sockets offer many of the same benefits of the 12-point design， including greater strength， more torque and reduced rounding of the fastener corners. But their main advantage is better grip on undersized fasteners and fasteners with badly rounded corners.Some sets include ratchets， extensions， spinners， and universals. Wright Tool socket sets are available in SAE and metric sizes.
