Master MagneticsMagnet Fastener - Rectangular with Mounting Holes, Zinc Plated, 2.70" Length, 1.08" Width, 0.50" Height, 25 lb Pull, Silver, Pack of 4, CBA275X4

I bought these to hold drill bits in my tool belt. I have two put together and they hold all the loose bits!

They are strong magnets claimed to have 25 lbs of pull force. They are strong but most certainly NOT 25 lbs. It failed to lift a 15 lbs dumbbell. So I would say it's about 10 lbs. They will still serve the purpose I bought them for.I'm making my own gun magnetic mounts. Just wrapping it with a shrink tubing 40mm in diameter. Each of them only costs me about $3.00 compares to the gun magnets that sell for $14~$20 on amazon. One magnet is more than enough for a pistol. But it will takes two for mounting a long gun.For the price and quality, I will certainly buy more for other projects.

So I ordered these magnets and I was highly disappointed...the attached picture highlights what they actually look like assuming they did not send me the wrong product. As the picture demonstrated these magnets hardly have any pull at all as they can sit right next to one another with little impact. I bought these to use to hold the cover down on my smoker grill and they did not work at all as the wind would blow the cover right off and I would find the magnets on the ground. One other notable point is the magnets are clearly not designed for outdoor application as they started to rust immediately after they were left outside. I ended up ordering magnets on Amazon (see link below) and what much more impressed...these things are ridiculously strong and work great...https://www.amazon.com/gp/product/B01GT8LUWS/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Worked real well for what I bought them for. I'll find many more uses for them.

Worked great for modding my 2DS-XL and 3DS

These are powerful magnets. The mounting holes make it easy to secure the magnets to a wall or just about anything else....simple yet effective.

SUPER strong magnets....Functional, but a little "dirty" looking.

Very strong! Excellent for all sorts of things, from the workshop to the home.

They worked great for a magnetic latch for my steel gate.

Not as strong as I was hoping, but everything else is fine as in shipping size and so on.

Good

Screw them to a 2*4 and a long stick to pic up small old nails and screws. Works really good slot of power.

Good quality and very strong. I use it on wordrobe locker.
