IRWINScrew Extractor Set, Hex Head, Multi-Spline, 25-Piece (53227)

Item works great. You don’t know you need them until you need them

Working to replace the rear shocks on my 2003 Honda Element, and the bolts were rusted solid to both the inside of the bushing and the welded nut on the trailing arm. I had to sawzall through them, which left me with a piece of bolt that was firmly stuck in the trailing arm nut. I drilled (awkward location), and used two or three other bolt extractors but couldn’t get the vice grips to hold them strongly enough. I wrestled with drilling and extraction attempts for ~2 hours.Finally, broke down and bought this set to use with a box wrench. After a couple of mins with the propane torch, and on the first try, the bolt turned and I could finally get it out. Success, and very great relief. Despite other reviews, the smaller bit was strong enough to work - I just took my time and lots of heat. So glad I bought this, my car is back on the road now and I’m a happy weekend mechanic with this set.

Not much to really say here. I had a stripped out screw in a machine body. Its surroundings were aluminum and plastic internals keeping electrical contacts and connectors made flame or heat out of the question. Took a cobalt bit drilled the just a small center hole of the striped out Philips screw to maximize contact.Used a small ball peen hammer to tap the right size extractor and gave it one extra good hit to really secure it once it bottomed out. Took a socket wrench with correct size SAE socket and slowly began reversing while keeping my left hand pressing down on top of the socket head.After a good amount of effort I was treated with a loud POP and the screw safely backed out w/o incident. If I had to drill it out I would have risked the drill bit wandering into the softer surrounding aluminum and pretty much damage things beyond reasonable compare.I like this set better than the ones that have a 3/8” square hole placed into the bottom because these hold more rigid and do not break or chip from hammer impacts. I’ve seen those sets with the square hole shatter from an electric impact gun, which shouldn’t be surprising as Neither this set or others are impact rated. However I can say that this set when used with an impact have only ever had their tips shear off instead of the body shattering.

I was attempting to perform a CVT fluid replacement on a 2016 Subaru Impreza. Embarrassingly, I ended up purchasing this set after I stripped the T8 hex socket of the fill/check plug.I initially tried a smaller size within the set which appeared to be going well. I seated the bit into the plug with a few taps from a ball peen hammer and carefully dug the bit in flush with a ratchet; slow and steady. However, the bit was approaching the bottom of its threads without the plug relenting so I switched to the next bit size. This larger size eventually did it. I'm unsure if the initial bit used 'primed' the plug so be aware of this.A few important things to note:* I did not drill into the center of the plug as suggested* Minimal rust penetrant was used* Absolutely no heat was applied* This was performed with temperatures at ~18F; dead of winter in the northeast US in an unheated garage* The bit that loosened the plug was not biting squarely into said plug (user error - minimal working room)* The plug was heavily rusted and last loosened by myself ~2.5 years ago and torqued to factory spec at 39 ft-lbsIn spite of all the above, this set did the trick and allowed me to change out that infamous CVT fluid. I can say that I'm extremely satisfied with this product. Hopefully I won't need it in the future but I'm extremely happy to know that it's available for other plugs if needed.If you can spare the extra money, I would suggest purchasing it proactively so it's already on hand. With 25 pieces in 1/32" increments (starting at 5/32"), this kit should satisfy most use cases and appears to be undamaged after use. It appears as though it will stand up to the test of time.Negatives (one star removed):* The etching on a few of the bits was marred on delivery making their size borderline illegible* The case was partially opened upon deliveryPositives:* Works as advertised under non-ideal conditions* Comes with a fairly rugged carrying case which locks closed and with minimal movement of the bits inside so they stay organized during transport* Should satisfy most, if not all use cases for the average car owner given sizes discussed aboveBe aware that as pictured, they are not socketed. They are of various sizes as well so you will need various wrenches or sockets to accommodate all bits in the set.Good luck with your extraction! Patience is a virtue!

I was trying to take some motorcycle rearsets apart, basically a zinc coated steel bolt out of aluminum that was secured with red thread locker. I stripped the hex, drilled and tried to use a conventional thread extractor, nope, nothing.I was about to head out for errands when the Amazon driver delivered the package. I left the car running, opened the package, picked a random extractor that was close and my trusty 1/2” socket wrench with an adaptor… out it came. Total time from Amazon deliver to bolt removal, 2 minutes.Buy this brand.
