Usually, if there's a Home Depot, there's a Lowe's nearby too. My Lowe's had stainless 1/2" up to 3.5 inch long.
I burned the zinc off a large eyebolt in my basket design. Used a plumbers torch and MAP gas. The shiny goes away quickly, then the bolt turns yellow like a post-it-note. And eventually the yellow burns away and the bolt was cherry red.
