Drill rod is available widely. You can probably get it from Grainger or MSC.
But I’ve only seen it in the “soft” condition (prior to heat treating). Ideally, you would cut it to length and then harden it. Otherwise, it might get bent.
But it certainly would eliminate any enlarging of the pilot hole, an advantage.
But I use the pass through hardware and I don’t face that issue.
