I think you guy are off on your Fastenal prices. I have an account there, and therfore get very good prices. I used to have an account through Lawson. While I believe they sell a superior product (tufftourque) or something, and it is branded with their name, I get MUCH better pricing through Fastenal.
Problem with Fastenal, is they get product from everywhere and repackage it. Lawson has the head stamped Lawson. Fastenal's service is MUCH better. Lawson used to ship part of an order, then charge me UPS for every part number as it came in, instead of waiting to ship it all together. The salesman made all the difference there. He would only come around onceor twice a year, over-order stuff, then ship it like we were dying to get it.
If I had to rely on a bolt to save my life, I'd take Lawson. Everything else, get Fastenal.
