2014 Sierra Truck Bed Mounting Hardware

[Shorsey]

I have a 5'8" box and I am looking for the size of the bed mounting bolts. I can't find the part number for the 2014 GMC Sierra 5'8" box. I can find every other year but 2014 which I need.  Everything seems to point at M12x1.75x45 but every online "fit checker" says they are not compatible.  Any help would be appreciated.  Thanks.

Welcome to the site.

 

Can you find the size for 2015 - 2018? All would be the same bolt.

take one out and measure it?

Jim & Davester,

 

Thanks for the quick replies guys.  The 2014 box is a replacement for my different year Sierra so I don't have the original bolts.  I was trying to be on the safe side and confirm the size of the bolts.  Once I started to dig around online for the replacement bolts nothing ever really confirmed what was compatible for 2014.  The surrounding model years used M12 x 1.75 x 45, however all the different sites and their "compatibility check" would not confirm for the 2014 model year.  It just made me question myself.  It makes sense to go with M12 x 1.75 x 45, but thought I would give it a shot to see if somebody else had come across something different.  Thanks again for the responses.
