These are not really “industrial strength” but they work great and are decent quality, especially for the price. I bought them to use on a sheet metal barn and they hold halters, rakes and other supplies with ease. Out of curiosity I did toss a dewalt drill in one and it held even though I ordered the medium size and the drill didn’t fit super well.

Very useful tools or helmets hanger.

These are quite useful and hold anything that’s less than 10lb. I think it can hold heavier items but I think it’s best to keep it light and the magnet strong enough to make it very convenient to affix it to any metal cabinet or poles.
