Great and strong!

Strong little magnets

Its difficult to put into words exactly how strong these magnets hold. Out of several I've tried, these seem to be the strongest holding - nearly permanent strength but still removable.I have used these for mounting secondary HVAC transformers where I can't easily drill into the metal panel, mounting wireless thermometers to high vibration fans and equipment where it may be damaged to drill in, as well as temporary mounting of meters or other equipment to metal panels.The 1/4-20 thread makes it easy to affix small devices, lights, etc which have camera tripod 1/4-20 thread, as well as the nut/washer allowing mounting of most things with a thru-hole. I have also had a couple things where the thread was too long and I was able to cut it short with a hack-saw and worked great.

The product does what it says... it is difficult to move once attached. It peel the paint off my iron fencing. Currently taken off the fencing and used to hold my smaller screwdrivers. It’s overkill but it keeps up with them.

Fit, form, and function of this product is perfect! I will purchase again in the future, as needed.

It is much bigger than it seems in its pictures. I mean that in a great way. VERY strong magnets. I’m going to need a couple more of these.

I designed a magnetic pickup tool with one of these magnets inside. I used PVC pipe with PVC caps on both ends. The end with the magnet in it has been sanded much thinner than how it came. I made a little bracket and bolted the magnet to the bracket, then tied a string to the bracket so I could pull the magnet straight up and down with the string. I cut 6 inches off the PVC pipe and added a 45 degree angle at the top then put the 6 inch section back on that and a PVC cap on that end. I drilled a hole large enough for the string to pass thru below the 45 degree elboe. Now with a loop in the string I can reach out and pick stuff up and then pull the string to make it fall off of the end of the tube. Sure beats bending over to pick up nails and stuff off the ground. You're welcome.
