Magnetic Truck Bed Cargo Crate

A simple way to keep stuff in the back of your truck from sliding around all over the place while you drive. 

Plastic storage crate from Target
Peg board magnets that I found in the tool organization section at home depot ( i used four per crate, but three would probably work)
M6-1.0 x 10mm hex bolts, M6 lock washers, and 1/4" x 1 1/4" fender washers from home depot (I used this hardware because the bolts matched the threads in the magnets I bought.)

 just pick one of the many holes on the bottom of the crate and screw in your magnet. the holes in the crate I used are 1" in diameter so the 1 1/4" fender washers work perfectly. Where you choose to mount your magnets may depend on the design of your truck bed. I positioned mine to fit in the valleys that run the length of my bed.

If you use the same magnets that I did, be careful not to over tighten or cross thread the bolts, because the magnets come with soft plastic threads. 

the magnets are strong enough to keep the crates in place, but not so strong that its difficult to pull them out.
