They aren't cheap per fastener, but if you only need a few, it works....
McMaster-Carr also sells small quantities BTW.
Lowes claims their bolts to be grade eight, but wasn't all that inpressed with their quality. Tractor Supply bolts look much better than Lowes. I think McMaster-Carr uses nothing but Unbrako (and maybe Holo-Chrome) bolts. I never knew they would sell them in smaller quantities, and I had an account with them. They do sell grade eight all thread down to 8-32 (maybe 6-32 aswell), and their grade eight is the real deal. I bought that stuff all the time from them till I got Karr to get it for me.
Slightly off subject, but still dealing with nuts and bolts (I have two ex's that will tell you I fill the "nuts" parts rather well). You guys buy good screws and use the cheapest hex key or Torx wrench money can buy!!! Buy good name brand ones like Unbrako or Allen brands. Those wrenches that Harbor Freight sells are a problem just looking for a place to happen. Even the ones Sears sells are better, but are not what they used to be. One of the best sets I've seen in 1/4" and also 3/8" drive (to use with a torque wrench) came right off the shelf of Walmart! Had Stanley's name all over it. Hex keys were very tight in the socket head on the cap screw, and that's what your after. Clean the threads and at least put a drop of light machine oil on them before using.
