Bolts in bulk? Anyone done this? What sizes?

But no matter how many sizes you have the one you'll need will have a different thread, fine vs course.

Yep. To solve this, I got a handful of fully threaded bolts in each major diameter, and then cut them down as needed for an oddball application.

Unfortunately I've never been this organized. Complicated later on, (junk Dakotas, etc) is that metric ****

Getting organized is a recent, and unprecedented move for me. When in the junkyard and scavenging nuts/bolts, I don't bother with any vehicle newer than early 90's. I was furious to discover my 94 Ram 2500 was all metric. Most any American vehicle from the early 90's and prior is standard thread. I don't do metric.
