Shop Iron 16023 3/8" Drive Damaged Bolt and Stud Extractor | Works on 1/4-Inch to 1/2-Inch Studs

If you are doing downpipe or turbo work on a Ford EcoBoost platform, do not attempt the job without this stud extractor. High-heat thermal cycling makes factory manifold and downpipe studs notorious for seizing, snapping, or rounding off. This tool grips studs firmly without slipping or stripping threads, making extraction effortless. It single-handedly saved hours of shop downtime and frustration during a downpipe install. It pays for itself on the very first stud—keep one in your toolbox. If you watch the video, I probably could have gone faster but I didn't want to chance it - it would have been a bad day if that stud broke.

Incredible on exhaust manifold studs

This may very well be the best purchase on Amazon I’ve made. Was skeptical at first because I hadn’t seen many people use them. Just the old school heat/drilling. Had 2 Ford 5.0L ignition coil bolts that commonly break upon removal. Used this as soon as it landed in the mail and had them out within 10 minutes and new ones put in place. The $17 spent on this saved so much time in labor or the possibility of spending more money in valve cover replacement

Purchased this to use in removal of a small wheel cap bolt that was too small in diameter to use with any of my other extractors. Unfortunately- this didn’t do the job either, even after heating the bolt and applying Kroil. Worked on it for 30 minutes and it didn’t budge- and the bit kept slipping off. Might work in other situations- but not mine.

I over-torqued a screw and the head came off but luckily I took a chance on this extractor and I was able to get it out! Took me a few tries until I really tightened the teeth down and it was finally able to catch and turn the stud! Really good quality even with just using an open-ended wrench on the outer flange!

Had a 3/8 stud that would not come out of an old tractor. Heated the surrounding area with induction then used this and it turned right out.

Used this to remove a stud from an exhaust manifold, with an air impact on the end of it. The tool worked great, no problem. Be warned, though, since it's self-tightening, you may find the stud stuck in the jaws of the thing. Also, it bears mentioning the threads on the stud will be annihilated by this extraction method. I tried to remove the extracted stud using a pipe wrench on the body of the tool and a box wrench on the bolt side, and it didn't budge. So (here's your warning) I stuck the impact gun on the bolt side and gave it a little bump of air... bad idea! It blew the retainer/ snap ring out of the tool. Amazingly, once I found it, I was able to reassemble and reuse the tool. So it definitely works, but will require finesse to bust the crusty stud out of the jaws afterward. A sturdy buddy to hold the tool in a pipe wrench while you whang on a box end wrench with a hammer would take care of it, or a good bench vise if you don't have any friends.

Excellent tool. Worked like a charm to extract 2 forty year old exhaust manifold studs (10mm dia,) on an aluminium motorcycle cylinder. Made in Taiwan, but seems to be fairly well built. I am looking around for other studs to pull out now just for fun ... :-) It basically looks like a chuck from a drill - but with some teeth to give it grip on the stud. I squirted a bit of WD40 on the stud first and let it sit for a bit. Then I used 2 wrenches to tighten it down on the stud (my stud had a non-threaded section in the middle - so it did not damage any threads). You will need a 36mm and a 24mm (or a 3/8 in drive - rachet handle for example) to tighten this puppy down. It states that it is suitable for "impact" wrench use, but I just used the wrenches and it worked fine. The key is to make sure its not slipping - so tighten it down good and make sure there is no debris on the teeth in the tool which will affect the grip (ie. metal scrapings from previous stud removal). The package states the tool can go down to 1/4 inch in diameter - but have not tested that yet. Definately worth the money - and proves the old saying that having the right tool for the job makes all the difference... Pro: - Decent quality and value - Solid build - Handles multiple diameters (adjustable) as indicated in description. Cons: - None - Clearance if you have a tight spot to work in (which was not my case).

Did what it was supposed to

Should of bought years ago

Ideal for those smaller studs.
