Each socket has a 6-point opening that fits the hex shape of fastener heads, allowing it to apply maximum torque without slipping. To prevent round-off under stress, it grips the flat sides of fastener heads rather than the corners. The large, high-contrast size markings are permanently laser etched into the steel surface, so it's easy to read even in low light when working. To protect against rust and corrosion, the black phosphate finishing absorbs and holds oil, repelling moisture. It meets or exceeds ANSI performance standards and comes with 1 year quality warranty.<br><br> <b>Include</b><br> 7 Pieces: 1/2-Inch Drive Deepwell 6-point sockets (inch): 1-3/8", 1-7/16",1-1/2",1-9/16",1-5/8", 1-11/16",1-3/4" <br>1 Pieces:Heavy Duty Blow Case<br><br><br> <b>CASOMAN is a professional manufacturer of hand tools,rachet and all kinds of sockets products.
