Review on 5pcs uxcell M12x1.75mm Metric Stainless Steel Nylon Insert Lock Hex Nuts for Secure Fastening by Mike Starling

I needed a dozen and wished it had 6 instead of 5. So four stars, my needs were not met and I had to buy three packs. This is a good solid stainless steel nut that will not exhibit magnetic attraction from a large 3/4 inch neodymium magnet. I checked if it really is stainless steel. My use will result in them holding aluminum stick contacts on super caps for a battery I'm assembling. I combine a small 12V lithium battery and 5 Maxwell supercapacitors that I bought online for a reasonable price. It won't be prohibitively expensive to have my own serious amperage super capacitive hybrid battery to start engines up to 5 litres. Each cap is 1500 farads and 6 circuits in series looks a bit, and charging between starts is done by an 18vdc solar panel in conjunction with multiple eBay PCB CC protection modules to provide charge balancing and protection as needed for manage lithium-ion batteries. to voltages and charging parameters. Now I load the lids, check them for drainage and hopefully they'll be up and running soon. Waiting for pucks for caps. I love nuts and they are one of the last things I need.
