I'm in the UK. Hardware stores? I remember those. Just about disappeared now. Local branch of Robert Dyas chain has some screws and basic fittings, glues and a wall of tools - but I dream about walking around one of the American stores. And don't get me started about threads. We have British Association, British Standard Whitworth, Unified (?), Metric, and a few others that turn up on machines 1940s to present. Phillips cross head screws, and Pozi-Drive. A Phillips driver will fit into a Pozi screw head but a Pozi driver will not fit into the Phillips screw head.
