I have a 1993 Chevrolet 1500, I had bad exhaust donuts that was causing an exhaust leak, this truck being as old as it is doesn’t require emissions in my state but won’t pass inspection with an exhaust leak. Each manifold on the V6 has 3 studs, totaling 6 studs which all but 1 of the original studs snapped off, luckily there was at least an inch of the studs remaining, I sprayed the studs with good penetrant oil a few times and this tool removed all but one (still working on it) but it worked extremely well. The only thing to note it is fairly large about the same size as a 1/2 inch drill chuck, and it can be hard to get it to release the broken stud after removal, this may just have been due to mine being really rusted and stuck, have a large adjustable or channel locks handy it will help in the removal, I would say an impact helped but I used a ratchet to remove two of the studs due to I didn’t have room for my electric impact and it worked fine just took a little longer. This device will only work if you have a portion of the bolt or stud sticking out, it will not work on a flush break. Review: BIG, STRONG, Life saver - Saved me in a very unique situation.. One of the Bolts holding my lower Control Arm snapped. Thankfully I exposed many inches of bolt by getting the part off, but my vice grips kept slipping. I tried pb blaster, heat, impact, a mixture of all of it.. then I found this and the bolt was out in less than 5 mins from touching the box. Caveat: usually bolts snap flush to the body they are embedded in.. this tool only works right with min. 1in. or ideally +2 inches of bolt material exposed. Also.. as other reviews have noted, this tool is BIG. So you also need quite a bit of clearance for it.. ## Features - TOOL INTRODUCTION - Damaged bolt extractor 3/8" inch drive. It is suitable for most drive tools and can be used with manual or pneumatic impact wrenches and ratchets as well as adjustable wrenches and flat wrenches. Heat treated alloy steel is very Sturdy and chrome-plated, will not be damaged by high-strength work, and will add lubricant to the internal rotating threads to provide better protection against rust and wear. - OPERATIONAL GUIDANCE - Simple operation does not need to be considered. Place the stud extractor on the stud and turn the bottom hex flat nut counterclockwise to tighten the jaws. After the jaws hold the broken bolt or stud firmly, continue to rotate the stud counterclockwise until it is removed.Then release and separate them in a clockwise direction. - EFFICIENT & VERSATILE - This stud removal tool is easy to operate and can help you get more rest time, whether it is the exhaust manifold, fuel plug, broken bolts, or broken, painted, rusted fastening screws The posts are effectively removed, but the threaded surface may be slightly worn due to the strong clamping force. - TRADITIONAL UPGRADE - Traditional bolt extractors are limited in size, and too many types of extractors waste space and cost. It's too much trouble for your mood, so we designed an auto-adjustable extractor that easily clamp the damaged studs for stripping, saving you valuable time，It is definitely a great addition to your toolbox. - GUARANTEE SERVICE - Provide 100% satisfactory and reliable customer service within 24 hours.

Is there any technique to it?** A: No not really. It tightens as a left hand thread. I tightened it as much as possible by hand and then attached the impact driver, I used the lowest setting on the impact driver so as to gently shock the stud loose. It worked wonderfully for my subaru exhaust studs. **Q: Will this work for an 8mm rounded off bolt?** A: Worked for me for a 6mm bolt and 8mm is 5 which is between .25 and .50 ( 1/4 Tuesday I 1/2) so I would think it would work well for you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works very well as stated, well built can take a beating *by A***D on February 27, 2024* I typically don’t leave feedback on a product, but with this one I feel it’s warranted.

However, once I took a closer look, the three jaws were loose and wiggly - like a loose tooth. I know they needed to move in and out to accommodate the bolt size but they shouldn’t move side to side. The tool was difficult to move by hand. As I hand tightened the tool, the 3 teeth didn’t always move in unison. When we actually tried to remove a bolt, the springs came loose and the jaws fell out. I guess you get what you pay for. Since I needed to remove the bolt, I purchased a PT Extractor from Autozone and instantly notice the quality difference. Save time and money and buy the better built extractor from the start. ## Frequently Bought Together - DEWILL Broken Bolt Remover, Stud Extractor Tool to Locks and Removes 1/4-Inch to 1/2-Inch Rounded Studs, Hexagonal Flat - Suitable for Rust, Painted, Damaged Waste Bolts - Spurtar Stud Remover Fit 1/4" to 3/4" (6 to 19mm) Bolt Extractor Nut Splitter With Knurled Roller and Cam Lock, Stud Extractor Tool for Broken Bolt Remover or Seized Nuts, Grip Damaged Screws - Shop Iron 51013 1/4-Inch Drive Mini Stud Extractor | Works on 1/64-Inch-1/4-Inch Studs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.bo/products/162653790-stud-extractor-1-4-to-1-2-inch-broken-bolt](https://www.desertcart.bo/products/162653790-stud-extractor-1-4-to-1-2-inch-broken-bolt) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-09-16*
