One Way Screw Remover, No.12, No.14, PK2

Too small for large 3 inch one way screed

Well for that price I pay I was expecting this tool to work out and did not deliver like they say. I was not able to take out the one way screw and also that L tool wish not sure what is that name of this tool. to loses that inside did not work at all I buy one separately for lose that inside part of this tool and follow instructions and did not work. that only good think I did have a back up plan because it was important for me to have this job done in one specific day. so I did buy this other tool they also claim to be one way screw remover and it actually work perfect and not just only to take out but also to put it in so it is actually serve as both remover/installer. here is a link so you can see that one I buyOne Way, Tamper Proof, Removal Tool #10 To #12 #6893http://tphsupply.com/tamper_proof_screwdrivers_bitsdid not buy it directly from this website I buy it in a local store but it is exactly that one I buy and for less money just want to let you know this is that one that will work for one way screws.

Well madd and worked great to remove two one way screws

This didn't even come close to removing one-way security screws. I purchased three different (sequential) sizes to make sure I had the right size and not a single one worked. They didn't even come close to grasping or budging the screw. Save your money. I did eventually get the screws off by using a Dremel to make a new notch and unscrewing with flat head screw driver.

Did not work after trying for over 1hr

This tool said it removed Reverse threaded bolts and It Does Not, for Security Screen Doors.

I want some thing bigger. but cost for return shipping is high, so I decide to keep it.now I have total of 3 set.
