had a brass screw/bolt with a completely rounded off head. I tried every trick I know, couldn’t budge it. Spend £4 in toolstation in this screw remover and it was out in three mins. Simply drill a small pilot hole in the bolt head. Then swop to the screw remover. Leave the drill in reverse and because of the reverse cut thread it drills in as it turns the bolt out. I’m sure a lot of you will already have these but it there might be a few people on here that this might help out.
They’re ok if the screw/bolt in question isn’t rusted/seized in. If it is, the screw extractor will snap off, leaving you with a seized bolt with a bit of hardened steel down the middle of it. Beware.
I find left hand drill bits (no it’s not a joke) better as the screw extractors are a right pig if they snap
I used one on a sheared frame head bolt on my beetle many years ago. I soaked it in plusgas regularly for a few days before. It did come out ok though
