THINKWORK Damaged Screw Extractor Set & Bolt Extractor Set, 2-21mm, 39-Piece Stripped Screw Remover, Lug Nut Remover for Removing Damaged, Frozen, Rusted, Rounded-Off Bolts, Nuts & Screws

They actually work very well

I think it's an amazing product, 12 out of 10, I needed it to remove a locking wheel nut, it caught the bolt at a funny angle and it still got it, I know it will be great with other bolts, if you're looking for a bolt remover, you won't be disappointed

Worked ok, didn’t have the size I needed but worked on others.

This set is brilliant and has saved me drilling several bolts/screws out. I have used the same pieces a lot of times and they seem to be very durable, I do use them quite hard (you have to hammer them) and I can’t see any signs of damage to any of the “Threads” it’s a great kit

Like all easy out products not manufactured by a major tool brand, these are rubbish. They just snap off and make drilling out way more difficult. I ended up welding to the stud and extracting the old fashioned way. These are a waste of money.

Extracted a rusted bolt from a marine engine sweet as a nut. Worked exactly as described, saved a huge amount of effort and worry.

I’m not sure if I’m lucky or unlucky, but this good looking little box of extractors arrived just after I had purchased a replacement toilet seat.Why was that a problem I hear you ask? Well the old seat had a faulty fitting screw that hadn’t been correctly manufactured - the cross head was too shallow. The previous owner had managed to get the screw in but there was no purchase to get a PH2 screwdriver onto it.Let’s call on my new extractor set. Spoiler alert - it failed miserably. The drill failed to get any distance into the screw head and the extractor didn’t grip at all. Of all things Superglueing a small bolt to the top of the screw allowed the gentle purchase I needed and the toilet seat was free!So on the experience of one unsuccessful usage my confidence is limited… the bolt extractors look more effective than the screw extractors hence I haven’t thrown my teddies out of the pram. Just be aware of the limitations that I have experienced.

After one bolt extracted the no18 bit is gone. This is one use only. Cheap chinese material
