Bed bolts

I'm needing to buy some bed bolts to mount bed to frame. Is the size I'm needing 3/8 in x 4 in carriage bolt?

Re: Bed bolts

Are you a steel floor or wood... Most of the suppliers have them... Classic auto Parts in KC, LMC, Brothers, of Mar-K... Those are all good suppliers for wood beds But Mar-K is where alot of them get their bolt sets... Classic Parts I think is a better Set for Steel Beds...

Re: Bed bolts

no need to spend the money for shipping // get good quality stainlewss steel at ace hardeware lowes home depot for a fraction of the price and end up with better bolts too

Re: Bed bolts

Whatever.. I would NEVER use bolts on my truck from a Lumber Yard... I can tell you there is a huge difference... But at the end of the day it is your truck...

Re: Bed bolts

I'm not certain what grade bolts are needed, but grade 5 would make me happy.
When buying online w/ no claims of quality or w/o a statement about where they came from, I'd guess the bolts are Asian and grade 2 or less.
As I recall, the bolts that came w/ my Global West body bushing set for the Camaro looked pretty Asian to me.
Maybe Fastenall, or ARP, or someone has quality carriage bolts?

Re: Bed bolts

I know I'm wearing out this thread...but what size and style bolts are needed to attach bed panel to bed sides. This bed has been apart for a couple of years and cannot remember what bolts are used. I looked on LMC and they do not give the size of bolts. They do not look like carriage bolts in the pictures.

Re: Bed bolts

What about the four bolts that screw into four holes on the front panel? There is two on each side in the upper corners.
