How reliable are rivnuts and self tapping screws for securing a Chest Style Tool Box?

I got this Chest Style Tool Box from UWS, ordered off Amazon, it's arriving tomorrow. From what I've read it should fit perfectly between the wheel wells, but how am I going to securely mount this to my truck bed?


I seen some older threads where people used bolts and a blend of metal and rubber washers, but they also said that it was really difficult to get washers and nuts into position and to stay still while tightening them up.

What are you using or have seen used to secure a Tool Chest?
I plan to carry heavier equipment/tools, and I often have young kids in the back seat, so it needs to have integrity.

What's everyone's opinion of Rivnuts and Self Tapping Screws? Would they be comparably as strong and secure as a combination of washers, nuts, and bolts?

 

We use rivnuts a lot at work, and none of them are used for heavy weight applications. Self taps can pull through just as easily. I'd stay conventional if you're looking at putting a hole in the truck either way.

 

Of the two choices, I'd use rivnuts. We used a lot of rivnuts in aluminum sheet metal at work and usually had no issues with them as long as we kept the paint out of the threads. They only had to hold the weight of the aluminum sheet together, not a tool chest.

 

I would use heavy duty bolts and washers like the other people. Would never trust rivnuts or self tapping screws in this situation, even if our beds were made of steel.

 

Thank you for your feedback. Since I need strength, Heavy Bolts, Washers, and Nuts it is.

I'm assuming that bed drilling and securing bolts to the underside is a common, but I haven't been able to find more than one thread that outlines the process.

Does anyone know of where i can find some good threads on people that have accessed the underside of the bed?

 

Just use some grade 8 hardware. Accessing the underside of the bed is as easy as getting under the truck. You’ll need 2 people to bolt it down, one in the bed and one under the bed.
