Question: Will this be able to remove a 4mm diameter screw which the head has broken off of?
Document: HE loved it, said he was able to remove old broken bolts with ease, and now wants to break more just so he can use the Alden 8440P Pro Grabit Broken Bolt and Damaged Screw Extractor 4 Piece Kit some more. Easy to use
Purchased this for my father who was planning to dis-assemble a wooden deck held together with phillips head wood screws. The Alden Grabit Broken Bolt and Damaged Screw Exractors would not remove the phillips head wood screws after several attempts on several screws.
Works amazingly good. I never thought I was gonna be able to remove this broken bolt from my trucks engine but using these I did! The only issue is the shavings coming off of the drill bit are VERY, VERY fine. They get into your skin like metal splinters and actually become airborne. At first I was only wearing goggles but after getting half a dozen metal splinters and seeing a cloud of metal flakes in my face I put on gloves and a mask.So use proper PPE!
Seriously, these have to be the best thing ever.I broke a screw head off when doing my valve cover gasket. This was able to pop the headless screw out with no problems.Index bolt on my rotors wouldn't come free (x2). Both times I had the bolt out in less than 5 minutes. And these bolts are held in with loctite. The ones that didn't strip required an 18 inch breaker bar.Took apart a throttle body and found that one screw head was stripping.
Broken license plate bolt(Rusted Head Sheared-Off)I didn't think this product would work(seemed like a cheesey info-mercial product)(Mechanic wanted 60 bucks cash to remove bolt,said he would have to drill it out from inside)It worked like a charm, very easy to use.Bolt came right out.This product paid for itself with one use.
I was extracting a bolt whose head had broken off. The burnishing side had almost no impact on the broken bolt. I had to use my own drill bit to create a pilot hole. Then the remover side BROKE almost immediately after applying any pressure. It's a waste of $20. What's worse is that the broken piece prevented me from using ANY extractor, and I must replace the piece I was trying to remove the bolt from. I expected a LOT more for my money.
These bits work as stated. I used it to get a stripped screw in my brother's Honda Civic and was able to remove it in a few minutes.
It works exactly as expected. I used as directed and was able to remove a stripped screw in less than a minute. Highly recommend it.
I bought this to remove a stripped bolt from my daughter's crib. We tried every other 'trick' to get it out and this was the only thing that worked. So happy I found this product otherwise I would not have been able to lower the crib. Hopefully I never need to remove a stripped screw or bolt again but if I do I know this will do the trick.
This is a great tool to take out broken screws. I used it to take out a striped screw head and it worked GREAT.
