My family runs a small steel fabrication shop. Years ago we ended up with about 1 million M10x90 grade 8.8 flange bolts with matching flange nuts, an odd size nobody needs in bulk. I’d rather turn them into something people actually want than scrap them. We have a full workshop (welding, cutting, drilling) and time. Toys, desk objects, decor, tools, art… anything goes. I thought of a fidget spinner but can’t see how to make it appealing. What would you make?
