Teng Tools 6mm Stud Extractor, £7.86

Tester Richard Newland

Time tested Six months (16 times)

What’s good? This is such a great little tool that I now wonder why I spent so many years without one. The simple answer is that I’d never had a seized stud to extract before, having always made do with liberal amounts of penetrant spray and two nuts locked against each other to remove the offending stud. All that innuendo aside, this Teng item works very well on all but the most obstinate of studs, and removed 7 of the eight on my VFR perfectly, and reinstated all eight new ones effortlessly, too. The one that was rust-welded in place, and snapped in half, still had to be drilled in the end. The tool has three rollers inside, and you slot it over the stud, then as you ratchet your half-inch drive (or use a spanner on the hex end), the rollers grip ever harder to remove the stud. Then it works in reverse to install a new one, all without damaging the thread. Available for 6, 8, 10 & 12mm studs.

What’s not? Nothing that I’ve discovered, unless you want to criticise it for not having the grip to remove seriously corroded studs that have effectively welded themselves in place. I maintain it’s worth £7.86 or anyone’s money.
