Olsa Tools Bit Magnetizer Ring - 2Pc - Demagnetizer Tool for Magnetic Screwdriver Bits - Powerful Neodymium Magnet for Allen Keys, Hex Bits, and Screwdrivers - Black - Part: 1287

They fit my #2 Philips screwdriver fine. I had to remove screws by reaching over my head while at the top of a ladder.Not one screw hit the floor. : )

Love these. Buy a couple sets!

The hole is small. It will fit some screwdrivers, but not all. Flatheads are especially likely to have trouble, since their heads are wider than their stems. This is a problem that could easily have been avoided had the manufacturer made the hole oblong, instead of hexagonal. That would have kept the end-product the same size, and the magnets the same distance apart; but would have allowed for more flatheads to fit through the apparatus. Thankfully, it should be possible to grind out the plastic somewhat to get the same sort of thing; but I'd rather not have to do this, lol.

This thing works one slide up then one slide down wala my screwdriver 🪛 is magnetized 🧲. Highly recommended five Star 🌟 Star 🌟 Star 🌟 Star 🌟 Star 🌟.

I have bought so many of these magnets. I use them on all of my drills and I give them to any techs I work with because not dropping/losing screws rocks! The magnetism is so strong. When I'm convincing others, I put a 3 inch deck screw on my magnetized bit and shake the heck out of the drill. The screw doesn't fly off and my parter is now on board.

Much smaller than expected. I was hoping to be able to put one on a normal screwdriver shaft while using the screwdriver, but that will only work on very small screwdrivers.I used popular Craftsman screwdrivers for size testing. It fit on a #1 Phillips screwdriver, but did not fit on a #2 Phillips. It fit on a small 1/8" flat screwdriver, but not on a 3/16" flat screwdriver. (Note: The size of the flat screwdrivers is measured at the end of the tip, but the tip gets a bit wider before the shaft so a 3/16" flat screwdriver is over 1/4" at the widest part of the tip.)The plastic "barrel" is 13/16" (21mm) long, but the magnets are only 9/16" (14mm) long (they don't go the whole length). The 1/4" Internal Diameter (ID) is the main problem.The magnet strength is pretty good for small magnets.These can hold a 1/4" hex shaft screwdriver BIT (without a bit screwdriver driver handle), as long as you don't need to put much torque on the screw.

I bought two sets of these, first for home use, then a second set for use at work. Makes working with all but the heaviest magnetic fasteners on a power drill with a sufficiently long driver bit infinitely easier. The only oddball thing is, for some reason (I haven't researched the purpose behind this seemingly industry wide decision yet; maybe there's a logical reason) it does not work with essentially any flat head screws. That is to say, I've yet to find any flat head (wedge head; channel head; notch head) that are ferromagnetic in the slightest, even though the shaft of the flat head drivers are, and will pick up loose screws or other ferromagnetic fasteners, washers, etc. So far all Philips head screws seem to be ferromagnetic, though. I'm guessing it's a difference is stainless steel alloy used to make the average flat head screw versus the average Philips head screw, which is unfortunate; and I haven't seen any drill mountable wedge lock heads to replace manual wedge locks for flat head screws yet either. But these are A+ winners for any application involving magnetizable fasteners.

Strong magnetic grip but will slide on some flathead screwdriver.
