grade 8 black oxide hex bolts

Hi,
I'm looking for resources to buy grade 8 hex head black oxide bolts. local hardware stores only carry stainless or zink plated hardware. I broke down and bought a box from McMaster -Carr but I don't need boxes of 25 bolts. Any info would be appreciated, currently I need 3/8-16 2 1/2 long but I have other lengths as well.
Thanks

 

Fastenal.

 

Get the zinc coated ones and soak 'em overnight in "The Works" toilet bowl cleaner. Then they'll be black. But they'll rust too.

 

Try a Caterpillar equipment dealer. All cat bolts are grade 8 or better and they come in black.

 

He beat me to it. They do have a cat logo emblem on the head though.

The Cat Grade 8 bolts will still have the six marks on them designating them as a grade 8.

 

Cat is a good source for all sorts of high quality fasteners and hardware. I especially like the various sizes and thicknesses of #8 washer they offer.

 

I have had real good luck with a small outfit-- allen'sfastners.com

Hi All,
Just wanted to say that Cat is the place to go. I tried a local Fastenal dealer nothing in stock. Went to Cat today they had all the sizes I needed in stock in and out 15minutes top. Thanks for the info.
