Mechanical Parts

This is a useful project checkpoint because several industrial targets draw on mechanical parts; the current recipe family also has tier variants to compare.

When it fits: Select the tier/recipe that matches the chosen project and its available inputs, not just the cheapest-looking single row.

The tradeoff: One source recipe run makes 4 and lists 5 Iron at Assembly I; 8 recipe variant(s) for this output are grouped together. Verify access where the pack is incomplete. Higher-tier routes can shift demand into steel or other shared materials; compare the full branch before switching production.
