## 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.

    Works a treat, Rust belt delight!
  

*by L***D on Reviewed in the United States on March 22, 2024*

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 )

    Time Saver
  

*by M***K on Reviewed in the United States on March 17, 2023*

I've used the 3/8 version for several years and been very happy.  I live on the coast of Maine so corrosion is a major issue on newer vehicles.  I also work on older 50 or more year old cars for my own pleasure.  You obviously want to use impact sockets or bits, and don't start out full bore on the impact.  I have the Snap on PH3050 and turn it way down for smaller fasteners.  It really works to shake very stuck nuts and bolts free.  Use a wrench to turn it as you finesse the air hammer.  I finally got the 1/2 inch to use larger sockets without needing an adapter, but the 3/8 has done everything I've ever tried.  Also It works well with impact hex or torx bit sockets and I use a 5/16 impact socket with screwdriver bits to shock things loose.  Don't use non-impact, I used a non-impact allen socket on a brake rotor screw and it destroyed it, fortunately it was warrantied.  This is a great time saver and Mayhew is a great company.  Don't buy knock offs or you'll probably break them before your bolts break free.  I reach for this more often than the torch or induction heating tool.  Works great and I haven't snapped bolts which becomes a major hassle.  It also doesn't take any room so things like recessed lug nuts/bolts can be accessed as long as you can get a socket on it.

    Awesome tool
  

*by A***R on Reviewed in the United States on April 26, 2024*

Very good quality and very handy. I use it mostly on aftertreatment sensors that I can't bust loose with a wrench or regular socket. You can beat on this thing all day and it will hold up.
