What separates everyday hardware from the specialist stuff worth stocking? This episode draws the line between Tier 2 and Tier 3 hardware—items that solve awkward problems but might sit unused for years. We break down rivet nuts, threaded inserts, Helicoils, T-nuts, cam-lock fittings, Confirmat screws, and more, covering tool requirements, compatibility issues, safety limits, and whether an assortment kit or buy-on-demand approach makes sense for each category. Plus: a prioritized purchase list and storage system for the serious home workshop.
