The Small and Medium MagNut set is a magnetic quick clasp specifically designed for the KeyBar but works on tools or other pesky items for which you need a quick mounting solution. The Large MagNut set is not recommended for use with your KeyBar. A set includes two MagNuts (a right and a left MagNut) each with a 1/2″ diameter split ring. NOTE: Magnuts made of brass & copper, the material does create a patina on the surface of the product.

The Small and Medium MagNut set is a magnetic quick clasp specifically designed for the KeyBar but works on tools or other pesky items for which you need a quick mounting solution. The Large MagNut is not recommended for use with your KeyBar. NOTE: Magnuts made of brass & copper, the material does create a patina on the surface of the product.

A set includes two MagNuts (a right and a left MagNut) each with a 1/2″ diameter split ring.

MagNuts come in a choice of small, medium or large aluminum,  small brass or small copper MagNuts with pressed 1/4″ x 1/4″ rare-earth (Neodymium Iron Boron in Grade N52) magnetic cylinder insert, which has a pull force of 6 1/2 lbs. Medium aluminum MagNuts have a pull force of 18 lbs and large aluminum MagNuts have a pull force of 22 lbs.

Note: These rare-earth magnets will lose their magnetic properties if heated above 175 degrees Fahrenheit (80 degrees Celcius). The strong magnetic fields of these rare-earth magnets can damage items such as television, computer monitors, credit cards, bank cards, computers, data carriers, video tapes, mechanical watches, hearing aids and loud speakers. Pace-makers may be damaged or switch to “Test-Mode” in the presence of a strong magnetic force, if a pace-maker or other bodily implant is in use, keep a minimum of 3 feet distance. Keep away from small children. Under no circumstances should you try to cut, saw or drill the rare earth magnet as the resulting dust is very flammable.  You should also not burn the magnet as it will create toxic fumes.

Brass and Copper MagNuts do aquire a patina and may not come as polished as shown in photos.

    the magnut set is a game-changer, i love it. here i thought the keybar by itself was a must-have, but this, for me, makes it twice as good. as others have said, the magnets are super strong. keybar didn’t cheap out here… neodymium magnets are the strongest permanent magnets you can get.

  16. Jonathan R. (verified owner)

    Really like the magnut. I’m going to buy a couple more for myself and give them as gifts. I thought the small was going to be to small but it is a perfect size for keys.

  30. Josh T. (verified owner)

    Works great for letting me switch between different car keys with my KeyBar. Only thing that is kinda irritating is the size is just small enough to flip over and stick to something inside the key ring supplied. I’ll probably look for a smaller key ring or eventually try the medium MagNut.

  31. Lupe Flores (verified owner)

    Strong everyone ask me where I got it from

  32. Eric F. (verified owner)

    Works perfectly for what I was needing it for. I have it attached to my keys and the other half to my gym Fob. Works great

  33. John C. (verified owner)

    I use it for my car key I liked it so much I ordered more to use for the different cars I have to keep the bulk down

  34. Pierce Richardson (verified owner)

    I know it’s scary to think about your keybar being held by one of these little things, but my I have pretty much every tool they have to offer on my keybar, and yes it is heavy, but these have yet to let me down, very secure. And I have the smallest one.

  35. Nicholas (verified owner)

    The best companion to your car keys! Even my friends are impressed by it! Bought the small size for my keys but do not be fooled by the size, the magnet is really strong!

    I was surprised at how powerful these magnets are. Very neat to use when handing off your truck keys or putting them back on your keybar.

  45. Pierce Richardson (verified owner)

    18 pounds if magnetic force in a compact nut? This tottally changes the game

  46. Cesar Isabel (verified owner)

    These are supercool. The small one is good for smaller secondary items, but the medium is strong as hell and I love it. I am looking to get the large ones but I’m wondering if they’re too strong since it says they’re bot supposed to be used w the keybar?

  52. Stephen Matherson (verified owner)

    Somewhere, someday, someone is going to save the world with one of these little magnets.

  53. Eric S. (verified owner)

    Surprising strong for it’s size. Can’t wait to try out the medium MagNuts.

  54. Thaddeus M. (verified owner)

    Definitely a must have for your keybar if you have a keyfob or even a pair of nail clippers. Very secure, strong magnet.

    Great for adding a key fob to the keybar. Good grip and keeps everything securely attached for quick access.

    Small and powerful

  59. Jake Fernandes (verified owner)

    These magnets are UNBELIEVABLY strong. I got the small one and its more than strong enough to hold my car key on the keybar.

  60. Andrew P. (verified owner)

    I really enjoy the MagNut for my keyfob. The only issue is that it gets stuck to the keys on the KeyBar and makes it a pain to flip the keys out or in. You have to separate the magnet from the keys and move it out of the way to push them back into place. I even put a smaller keyring on the MagNut to try and stop it from flipping inside itself but no luck. Maybe I’ll try to mount it rigid/fixed to the Titanium keyfob ring in a location that is out of the way always.

    Such a great tool to add to my KeyBar. Strong enough to hold my KeyBar but easy enough to take it off real quick if I had to use my keys for something else. Over all a very handy item in addition to my KeyBar

    These little things are very well made and surprisingly strong. I unlocked a series 5200 lock (heavy) and hung the lock and keys by this tiny magnet! These things are fantastic!

    Small Copper Hexnut is a nice addition to my keybar. Helps me keep the weight off my ignition by detaching the key fob from the rest of the keybar. Super strong magnet.

  93. Tyler Cannon (verified owner)

    This is really strong great for holding your key fob to your keybar

  98. Matthew Moses (verified owner)

    I got the small and it’s as small as I think you would want to go. I use it for my keychain flashlight. But I would recommend going to the Medium size if you want to attached your keybar or key fob to it if you plan to carry something attached to it outside a pocket.

    Just what I was looking for

  101. david (verified owner)

    If your looking for a way to keep your car key and fob stand alone this is the way to go.

  102. Bradley B. (verified owner)

    I ordered the medium as they were out of the size Small. Glad I read the advice that the Large was in fact VERY large.

    The medium works well.

    A word of caution… I carry a benchmade pocket knife (very sharp blade) and had separated my vehicle keys from my house keys one my key bar to let the wife take my truck.

    I usually keep knife and keys separate, but must have opened a box and put the knife back in my pocket with the MagNut magnet.

    The Medium MagNut has enough strength to open the blade of your pocket knife. Luckily my reach was a slow one. The blade was open and it could have gone another way.

    Great product… just be cautious about the MagNut and your pocket knife blades.

  103. Brandon Lodder (verified owner)

    Way better than the cheap Chinese knock-offs I had. If I would’ve had these my last Keybar probably would’ve stuck to the mower and not gotten run over by the mower!

  104. Wu Fei (verified owner)

    is too good to handle car key

  105. Nic Chew (verified owner)

    The copper came out awesome, and the magnets are surprisingly strong for being the small ones.
