So I bought a tool box for my '06 chevy silverado. I was thinking of ways to bolt it down so me and my buddy Dave came up with the idea of using Rivnuts. We just bought a rivnut gun for the shop and havent used it yet, it works exactly like a rivit gun. So I figured who uses the stake pockets so we drilled 2 holes each in the front pockets and installed the rivnuts. I recommend to everyone, goto your local swap meet and but a rivnut gun...they are cheap and worth every penny. We got ours for about 20$. Now I use 2 1/4-20 bolts on each side to hold the box in. And I can take it out and not worry about the hole getting all goofed up. And I dont have ugly holes in my bed rails or my bed rails wont get all bent up from the J-Hooks that most tool boxes use. I'll take some pics when I get home today.
