For any of you fine folks that have mounted a toolbox (or any accessory) to your trucks, what fasteners did you use?
I need a good toolbox, but with the aluminum body panels, I want to avoid any galvanic corrosion.
Any input is appreciated.

 

Don't drill through the bed, use J hooks or one of the several mounting kits out there that allow you essentially clamp it to the underside of the bed top rails.

My WeatherGuard truck box came with hardware specific for aluminum boxes. It includes plastic inserts for the hole and some kind of molly bolt. Haven't had the time or nerve yet to try them out.

 

Thanks guys! I'll definitely have to DIY it, most accessory shops around here wouldn't even think about such.

 

I ditched the included J-hooks included with my toolbox and got a set of these. $10 shipped. They don't deform out like the J-hooks. My '13 is steel box, but the fasteners are aluminum so I would imagine you should avoid any reaction from dissimilar metals. I included a couple pics as well. You can see where the J-hook started to pull the plastic bed caps out as well. The new fasteners avoid that.

Just use plated hardware, 99 percent will be plated no matter where you but otherwise the hardware would be stuck together in the bin. Your truck bed is bolted in with plated steel hardware already.
