Review on 🔩 Comprehensive Coarse Thread Hex Nut Assortment Kit - 495Pcs Metric 304 Stainless Steel 9 Sizes (M2-M12) by Jose Hughes

While I can confirm that this set consisted of metric threaded fasteners, the male thread size on some was definitely not metric. I've used them as a last resort when I needed something disposable, but other than that I think they're complete junk. What's the point of having a metric threaded nut that fits a 1/2" wrench instead of a 12mm wrench? I suspect this is a manufacturing defect that they hoped would go unnoticed. Maybe you're lucky and don't have this problem. My business is almost exclusively metric and I've never seen anything like it before. My recommendation is to spend more money on real sets as well.
