They were completely ineffective at this task. Still, if you know enough to not normally strip screws while placing them then I figure you wouldn't need the extractors unless the screws are soft metal. I'm currently building a deck railing and to attach the rails to the posts I have been placing some long #10 stainless steel screws in the brackets (#2 Phillips drive and a flat head). They should work in such circumstances to be useful to somebody with some experience with driving screws properly. So I purchased these screw extractors. (Yes, I predrilled pilot holes and yes, I had the driver in reverse while trying to use these extractors). I tried different size extractors and even drilling into the screw head with a 1/8" drill bit in an attempt to provide these things with something to grip - all to no avail.
A couple of those screws did not make it all the way in before my power driver stripped the heads and I could not back them out with the driver in reverse. All they did was spin without budging the screw - I didn't even detect a momentary grip - and hollowed out the screw head. I was able to return them to Amazon without hassle.Jackytar Even after backing out the screws most of the way with a pair of pliers - to the point where the screw was wobbly in the hole - these things could not finish the job.I'm not a professional carpenter but I suspect that the root of my problem is that these expensive stainless steel screws, while having the anti-rust properties that I was looking for, are a softer metal.
I had a stripped screw on my laptop and took me forever to remove it. Great tool. With this tool, it only took less than one minute.
Was able to use the No. It worked just as promised. 0 to get out a stripped laptop case screw.
Easily removed a screw with a stripped head from a cell phone. Even though the smallest size was #0, I still got it to work on a #00 head screw.
I attached it to a ratcheting screwdriver, made a quick turn and when I shined a flashlight down in that hole I'd been struggling with for days, the screw was resting there, no longer screwed in. I had stripped the head of a recessed screw on my laptop. I don't normally review things so quickly, but I was amazed at how well this worked. I bought this, not knowing if it would work, but worth a shot. Fantastic. I honestly didn't expect it to work so quickly.
