32Pcs Bolt Extractor Set, Extended Version Impact Bolt & Nut Remover Set with Hex Adapter, Stripped Bolt Remover Tool Kit for Removing Damaged, Frozen, Rusted, Rounded-Off Bolts, Nuts & Screws

I purchased these as another person had said they worked well on an old Land Rover. My Defender is 22 years old and the original bolts still hold the axles on. They are severely rusted and were all rounding or snapping off requiring me to drill them out and rethread them. Replacing my calipers turned from a 2 hour job into a 3 week job.These have been an absolute life saver.

Very good tools

Dismantling an old Land Rover with lots of corroded boltsWorks really well

These will soon pay for themselves in time saving.I Used smaller sizes on lots of bolts underneath. All were rounded off. These just bite into what's left of the head and amazingly extract them.The spiral/teeth have a more aggressive geometry than some extractors, I have of a known brand. Therefore they work better.I also like how the sizes of common small sizes go up in 0.5mm increments.Which helps give you another option if the head is really rounded off.

I spent hours trying to free a never unfastened nut and bolt on a 14-year-old car on Saturday. Even after plenty of WD40, open spanners were no good, ring ones neither, grips couldn't touch it and what started as a nut was rounding off and looking more like a thick washer. I resorted to trying to drill the nut and snapped the drill bit. After what too long I gave up. Then I saw this, which I ordered yesterday and came today; first time I have used one of them and I was doubtful. I thought the thing would shear with the force required or else just do a better job of re-shaping the nut. Delighted to be wrong the thing was off in no time. Wish I had ordered it at the start.

This tool set has proven itself invaluable on several occasions already! They grip even the most rounded bolt heads and gently twist them off with a little bit of penetrative oil to assist. Can also lightly hammer a slightly smaller size on to get a good grip on a stubborn bolt.

Not great. 19mm extraction socket broke after first use. I followed the instructions and it broke. Luckly I was not hit by the flying part.Please wear eye protection.

These were bought to help pull me out of the shit with 3 rounded Allen key bolts on a crankshaft pulley.All 3 bolt came out on the first time of asking.With the first bolt I extracted, I drove the socket to the hilt for maximum engagement, just to be on the safe side.The remaining 2 bolts came out even with only 50% of the depth of the bolt head covered.Great set for bailing you out of a tight spot!
