1/2 x 1/8 Inch Neodymium Rare Earth Countersunk Ring Magnets N42 (20 Pack)

Neodymium Rare Earth Countersunk Ring Magnets N42

I used the magnets to build tools for metalworking machines. The magnets hold fixtures in place until materials are otherwise clamped. Total Element magnets have the countersink on opposing polls, which is very handy.

Just what I needed

First off, the ordering, packaging and shipping processes are excellent. All of my items arrived promptly and in excellent condition. As for the purpose, I am using them to hold plywood covers to the back of a model railroad layout. They can be removed for access to the tunnels, so I needed something that would not easily slide off. These magnets are surprisingly powerful for their size and are very brittle, so removing them from the metal washers requires 'sliding' and not 'pulling'. As of this writing, I have four panels in place and secure, and removing them is quite easy if one understands the nature of neodymium magnets. Attaching the magnets and washers was via wood screws driven gently by hand. As I said, the magnets are very brittle, meaning power tools should be avoided. Overall, an excellent product at a good price with A+ service.

Strong for the size!

I am using these in my woodshop to hold various tools and jigs. Great holding power for such a small magnet! Plan to get some larger ones for other projects. Quick shipping!
