Westward 9/16" Alloy Steel Socket with 1/2" Drive Size and Full Polished Finish

½”-Drive 6-pt. Deep Socket features a restrictive interior shape with six meeting points. This means that only the correctly-sized socket will work for a particular bolt. The advantage of this is that a correctly-sized socket will fit snugly onto the bolt. This greatly decreases the danger of rounding the bolt's head with a socket. Deep sockets are better for specific jobs instead of general use. If you have bolted joints, they make a much better option for your socket wrench than shallow sockets. Deep sockets are better choice when the length of the bolt means the nut will need to go further into the socket.
