Another vote for McMaster Carr - it's "Amazon" for people who do stuff.
If you're not happy, you can return anything for a refund.
I recently bought a kit of jeweler's files and the round file diameter was larger than the spec on the product page (too large for my needs).
They refunded my CC (said keep the kit) and sent me a single round file that met my needs - for free.
