The small one measures 2 3/8" in length, while the large one measures 3 1/4" in length.
Yes, drill refers to the drill bit size that is recommended for that particular bolt size; in this case, a 6 mm should suffice. Use a drill with enough length to wedge the extractor into the bolt. Drill down to gain as much surface as possible by using a center punch to center the broken bolt to be drilled. I hope this information is useful, and best of luck. It will also help if you can warm up the area.
You might be able to remove it with a socket (SAE or metric) and a breaker bar, depending on the size of the fastener. I recommend using a breaker bar (non-metallic). ratcheting), because if you really need to lean on it, you won't damage the ratcheting mechanism. Another option is to use a breaker bar of the next size up (i.e. , use a 1/2"-diameter drill bit Instead of a 3/8'-inch breaker bar, use a drive breaker bar. breaker bar to drive). You'll have more length and muscle to remove a stuck fastener, and you won't damage the ratcheting mechanism in the process. At the very least, use the breaker bar to LOOSEN a stuck fastener first, then use the ratchet to remove it quickly. Finally, if you're having trouble removing a fastener, even with the breaker bar, look to see if epoxy was used to keep it together (or to prevent removal). Apply a few drops of a solvent (such as nail polish) to make the job easier if it's epoxied. Avoid using solvents if you have the ability to use heat, as they can cause a fire.

Selected User Reviews For Mayhew Pro 37331 Screw Extractor Set, 4-Piece
It's a fantastic product and the perfect tool for the job. I had two broken spark plugs in my 1994 Dodge Ram 1500, so I bought the set and hammered it into the broken threaded piece of the plug with a 1/2" socket on the other end, based on another reviewer's picture of the same problem. I needed 3 feet of leverage pipe on the ratchet's end, which had begun to bend slightly, and all of my strength to turn it out. I was expecting the tool to be chewed up, but there wasn't a single roll or chip on the sharp edges, which surprised me. The tool also did not twist in any way. It gets six out of ten stars from me. It's become an important tool in my arsenal. It's even packaged in a sturdy stitched cloth case.
To replace a set that had gone missing, I had to purchase a new set. These have become my favorite extractors of all I have ever had to *% @ I use them because they're tough, and I believe I've had a higher success rate with them than with any of the spiral style in a few brands, or the other two square brands I tried. I'm glad to see these are still manufactured in the United States, and I'm hoping the steel is of good quality. In my old set, I did break the 3 and had to replace it, but that was due to both user error and a hole that was slightly off center and crooked, and that stud probably should have been completely drilled out from the start anyway. A couple of the others have taken a lot of torsion and haven't broken or twisted the extractor, which is what sold me on these Mayhews because I can't tell you how many others have snapped or splintered in similar situations, even "better" brands. A coworker has a few Rennsteig/Knipex extractors, which appear to be the bee's knees in many situations, and I may pick some up, but for now I'm sticking with tried and true.
Because of the state of the others, I assumed it was simply rusted, but PB Blaster and heat were ineffective. br>br>I ended up twisting the plug in half with an impact socket on a breaker bar. That wasn't the plan in the first place. After watching numerous videos of real mechanics removing broken plugs, I decided to purchase this fluted style tool rather than the twist style. br>br>As you can see from the photos, the tool performed admirably. The plug had been installed with crud in the threads and was not cross threaded, as it turned out. br>br>After removing the old plug, I cleaned up the threads with a reverse thread chaser, and the new one went in like butter. br>br>The plugs have 14mm threads, so I used the largest tool in the kit, as well as a 7/16" socket on a breaker bar, to install them. I used a magnetic pickup tool to remove metal shavings from time to time while continuing to use the PB Blaster.
I tried using the second largest one with a 3/8" socket, but it wouldn't grip and kept slipping, so I had to buy a 12 point deep socket and use a 2 foot pipe for leverage to ease it out slowly after sprinkling it with seafoam lubricant the night before. It's now time for the four 02 sensors to be installed.
The best extractors are square extractors with a slight taper that can be driven into the pilot hole. Spiral extractors should not be used to expand the broken bolt. Spirals have never worked well for me. The way to go is either square or spline. These extractors from Mayhew are made in the United States. made. It is impossible to make a mistake.
tool. Made in the United States of America! Tools made of good steel and well-made by a company that has been producing tools in the United States for well over a century.
It's well-made. I wish I had known about these things ten years ago. I could have saved a lot of money if I had known about it earlier. Simply drill a hole in the broken fastener, insert one of these, and tighten the screw with a wrench. The hole is not stripped out or expanded with these.
I was instructed to remove the square type as quickly as possible. I was able to save a significant amount of time and money thanks to these. I had a broken spark plug, and all that was left in the head was the threaded sleeve. I tried everything I could think of and still didn't get a bite. I ordered these, and they arrived the next day, so I started with one of them. These plugs had been soaked in pb blaster for three days before I started, and they still broke. So, with the square in place, I attempted to back it out, but it remained stuck. I was about to break the out because it was so tight, but this bit didn't slip the first time, so I worked it out and you can't tell I used the square out. The money was well spent. Over and over again.
