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

It did the job I used it for, which was removing severely rusted, broken exhaust manifold flange studs that were 18 yo OE. Whether the fact I soaked the studs in penetrating oil for a week helped, it nonetheless removed them. Given it's size, it is limited in applications. You'll need a couple of inches, or so, of clear space around stud to be extracted and it's range of stud sizes is limited. You need the space to get the puller on as much of that stud as possible. It is open all the way through for long studs which would require a wrench or cut the stud down for ratchet/impact. Did not say whether it was rated for impact wrench, but it was what I used to drive it and it held up. You do need a couple of wrenches to loosen it to release the extracted stud once out It grips/bites that hard. Of course the impact wrench may have compounded that that. I was hoping to not have to remove the manifolds and drill them out and the fact I had enough clearance around the flange was helpful. Finally an automotive repair that went off without a hitch. I've seen this advertised elsewhere on Web at *significantly* more than here and unless you're a full-time wrench it may very well sit more than used. Either way, if one ever needed it, you'd have it. Well worth the investment, even if used one time and it works. However, with Murphy's law, it could snap the stud off flush and then you're drilling anyway. Work smarter, not harder.

This tool is amazing. Was attempting to change exhaust manifold gasket and one of the old screws broke off. Not a drillable location. This gift from heaven bit hard into what was left of the bolt and out it came! I was pretty ecstatic.

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.

Tool broke literally in half first try on a tiny bolt...very cheaply built ..DO NOT BUY

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.

Giving it only 4 stars because the first one I purchased broke on me. The snap ring came flying out as I was trying to extract a snapped stud, and it didn't go back together well after that. After reading the reviews on here decided to give this tool another shot and it survived the job. I am sure for those with Jeep Grand Cherokee's 93-98 if you ever tackled trying to remove the studs in the unibody for the gas tank skid and hitch it's not a quick job. There is patience involved with using this tool. I let the studs I was tackling soak for 2-3 days, then attempted the job again with the 2nd tool with success.

Get it so much worth it in love it this extractor took out the most burnt looking oil stud from my thermostat housing I was skeptical it wasn't going to work but it did it was in a tight space too and took it out like nothing get it won't regret it

Only works on very small studs. Chances are you need the larger one, but if you broke the head off something small this can grab what’s left. You need several threads exposed to be able to grab as well as a fair amount of space around the stud for the tool and quite a bit of space above, but if you have all these it will definitely extract the broken bolt.

Did what it was supposed to

Ideal for those smaller studs.

It worked as described.

I purchased this to remove turbo adapter exhaust studs from a 2017 F150 Ecoboost .. This tool is a MUST for this job, I used a 2 foot long 1/2” breaker bar with the extractor and worked like a charm.. Worth every penny ⭐️ ⭐️ ⭐️ ⭐️ ⭐️
