I bought these as a Christmas gift for my boyfriend. He is a lineman and said these are great for his job. He even uses them around the house for projects.

  • Good set, best price
Size: 5-Piece Set Style: 5-Piece
I wish I could have gotten the set with the 3 in 1 socket substituted for the same size one that came in the set. Yes, I’m sure it would have been a little more expensive, but I wouldn’t have had to buy the $50 3 in 1 socket additionally…basically having one almost duplicate socket.

  • Must have for lineman
Size: 5-Piece Set Style: 5-Piece
Although the 3/4-9/16 socket is the most useful, the rest of the set has its use. This set is much easier to haul around than a typical socket set. Having the combo socket has saved me in a pinch a few times. If you dont want to spend the money on the whole set, I would recommend buying the 3/4-9/16 socket for sure. It saves time and the hassle of constantly changing out sockets. ... show more
