There are some businesses that have the 72 hole cabinet like LD1 mentioned, and come with a stocked assortment price. Fastenal may have something like this, but pretty pricey. I'm pretty fortunate to have a couple small independent businesses that can provide the same thing for about 1/2 to 2/3 the price of Fastenal. One is Phoenix Rose, near Newark, Ohio.
Request Rejected This guy is great to deal with. His business/warehouse is right on the property where he lives, so it's a low overhead operation, but carries quality stuff. I've bought specialty bolts from him, like 1" X 12" Gr. 8 bolts for my beam trolley's. I ordered 1 at a time, at separate times. Not charge for shipping, and bolt was like $3.00
ea/ at the time. He gets shipment daily, so no long waits. Fastenal required me to buy a box of 25 of those bolts, to get 1.
Another is Calandra Industrial Supply in Lancaster, Ohio. Just about any bolt you can imagine, except automotive type fasteners. You might check in your area, and see if there is a similar business.
I know Phoenix Rose has a stocked cabinet suited to fit about anyone. from the occasional handyman, to supplying a factory stock room with fasteners.
