Hi guys! I'm really into construction and safety protocols and I've been reading about it for the past month. I just want to know what the difference is between these companies. If I was a sub-contractor why would I choose Fastnal over Supply House or Supply House over Grainger?

Doesn't matter shop by price. Every machine shop etc has for example MSC, Fastenal, McMaster-Carr (superbly designed catalog/site) etc. 



If you can order in advance from a specialty supplier you will generally pay less than those suppliers who exist for one-stop shopping by busy purchasing depts who do not use experts to buy stuff.



Instead when I worked for a welding school I did my own research for items then handed the info to Purchasing who loved me.

I'm pretty sure the idea is you open a request for tender and these guys all compete to see who can offer the sweetest discounts to get the contract. But this of course only works for governments and megacorps, not Billy Bob who just needs a dozen screws and a hammer to finish his deck

My company wants us to only order from grainger. "We get a corporate discount lol." You see how the Grainger one is $461 more? They'd probably give us $350 off their price. And it would take at least 2 days to get to the store.
