Building & Construction Products parts lists

BOMwiki maps 123 building & construction products products, each exploded into a recursive bill of materials: 19,434 parts in total, down to individual fasteners and cells. The largest is the insulated sandwich panel line at 1,856 parts across 9 top-level assemblies; the simplest is the lock pick set at 17. Across the domain the same components recur: fastener set, connector, microcontroller and bare PCB appear in most of these machines, and each is a single shared page here, so a correction to one fixes every product that uses it. Open any product for its parts diagram, the function of each part, and the full bill of materials.
