> Something that stuck with me was that dude had an uncle that worked at a bolt factory down the road, and now there is literally no way to source domestically made bolts.

US manufactured fasteners are available*, the Build America, Buy America Act created a market for them. You’re not going to find them at Home Depot or your local hardware store, professional supply houses will sell them to you.

Waivers are available if no US supplier is available, but there usually is a US supplier.

I assume bolt manufacturing is automated to the point where you load up a CNC machine with steel hex stock and get boxes of bolts on the other end, there’s not a ton of labor involved. The machine cuts the hex stock to length, then removes material to create a cylindrical shaft and then threads are cut.

* By US manufactured, I mean ‘compliant with BABAA requirements’, which is something like 55% of the materials and manufactured here.

Only extremely specialized fasteners are CnC-milled or machined. Here is a video of how one American company makes screws: https://youtu.be/Z8siZfGmnjQ?si=24aAFhk87RRKdPt4

I'd be shocked if bolts worth a damn weren't forged
