Irwin Industrial Tools 394002 Bolt-Grip Expansion Set, 5-Piece

I had a bolt with a stripped head in a very inaccessible area on a wind turbine. I had tried the Grip-Tite and had no success, I tried the 3/8″ Bolt Grip socket and it slipped off also. I was about to give up and then I realized with the Irwin design I could set the teeth of the socket by tapping it on. I had it on a foot long extension and used a hammer to tap the socket on, attached a long handled ratchet and SUCCESS. I did have to tap on the bolt to remove it from the socket, but there were no signs of wear so I think these will last forever. I would recommend getting the other set to fill in the gaps, but this is a great basic set.
I wish I bought this earlier! Makes easy work of removing stubborn bolts. For stubborn screw removal, you may want to look at:Alden Grabit Broken Bolt and Damaged Screw Exractors, 4-Piece Set
I’m sure Irwin tools are great products. I own many Irwin tools including the starter Bolt Grip set. However the problem I am encountering is the Expansion set is apparently not available. I ordered this set back in Aug. I’m still waiting. So before you try to order this set, make sure you don’t need it any time soon.
Try and try with other tools that never work…and then use one of these!! Great value for the price. Buy the original five piece set and then add this expansion set for more versatility…..one stuck bolt will never stop your work again!!
I have used these several times since I bought them. They have got me out of a jam every time. They work great!
