Review: Works a treat, Rust belt delight! - A must for automotive under body work in the rust belt. I used it to get out some M6’s that would have snapped off with any other means. No damage what so ever to anything, the socket, fasteners, and surrounding areas were completely undamaged. Zero reservations about reusing the bolts. This product is at least as good as percussion and nearly as good as heat (propane torch). FAR BETTER than ANY penetrating oil. The bolt cracking loose is the oddest feeling. Id highly recommend an air chisel with a regulator. My 114GQC has an internal regulator, being able to throttle the speed made the experience a dream. ( The 114GQC is also highly recommended )
Review: Fantastic for Ford Triton exhaust studs. - Is this the best tool in the world? Does it work flawlessly even if your an idiot and don't know what your doing? Does is compensate for lack of experience and skill.... The answer is no...But it is a fantastic tool to put in your "OH $%&# drawer" in the shop and try it when your needing to remove stubborn bolts or studs. YES! Just used it on a Triton V10 and got 10/10 studs out with out them snapping off! If you've ever tried this job you know what a PITA it is! Yes I had to use a combination of penetratingly oil and the hot wrench, but still they are all out. Note: My engine is out so I'm able to access the studs easier, I also use this tool in combination with bolt extractors because of course all the nuts are rusted to oblivion. Bottom line, Great Quality tool, it works great, and well worth the money!

## Questions & Answers

**Q: I can see how a 3/8" drive socket fits on the end of the tool but how would I use it for Torx or Phillips bits?**
A: you can buy 3/8 socket type bits. Or if you own a impact driver like this one12PC HAND IMPACT DRIVER SET SID12PBA . Make sure the bit is rated for impact use. Normal bits have a good chance of blowing apart.

**Q: Is there any advantage to this item versus the Lisle 60260 seized fastener remover kit?**
A: Mayhew is very tough,but no kit.

**Q: Where is this item made? Thanks,**
A: Mayhew #37315 is Made in the USA

Thanks, BW

**Q: Why deceptive picturing ?? i asked questions prior to making my order for 3/8" drive & i got exactly opposite of what i asked about.   why??**
A: You need to ask the SELLER about this if you didn't get the correct tool.  Good luck.
