Where can one purchase an Acme threaded rod?

You can't purchase an "Acme threaded rod" because Acme is not a specific type of threaded rod, but rather a type of thread profile. It's a widely used thread profile, but it's not a brand or product itself.

Here's how to find what you're looking for:

1. Specify the diameter and length: Do you need a 1/2" diameter Acme rod? A 1" diameter? What length are you looking for?

2. Consider the material: What material do you need the threaded rod made of? Steel? Brass? Stainless steel?

3. Search online or at local hardware stores: Once you have the specifications, search online retailers like Amazon, McMaster-Carr, Grainger, or local hardware stores like Home Depot, Lowe's, or Ace Hardware.

Here are some search terms you can use:

* "Acme threaded rod" + diameter + length + material (e.g., "Acme threaded rod 1/2" x 12" steel")

* "Threaded rod" + diameter + length + material + "Acme" (e.g., "Threaded rod 1" x 24" stainless steel Acme")

By providing more details about your needs, you can narrow down your search and find the Acme threaded rod you're looking for.
