Not unusual for one to get missed during assembly at the Michigan plant. Build quality tjere is not spectacular. The Mexican plant where the HDs are built actually has a much higher build quality score.Isn't that a body bolt. How the heck is it missing? Those things are torqued pretty good and long. I needed a breaker bar to loosen mine when I installed my bars.
Big ring of cab bolt snatchers out there in NY?Some scumbag probably needed one and snatched it in a parking lot.I'm ready for the day I catch it happening to my truck.
I'm not sure you'd find a bolt like that in a hardware store, and I couldn't find and spec's for those bolts, (ie: grade, thread, finish). Maybe Tractor Supply??I was installing the stock running boards on my 2011 Ram and noticed one of the bolts at the bottom of the frame is missing. Was wondering if anyone knew where I could buy a replacement.

Can you explain to me in plain language exactly what makes a fastener a "one time use" fastener. Thanks.I'm not sure you'd find a bolt like that in a hardware store, and I couldn't find and spec's for those bolts, (ie: grade, thread, finish). Maybe Tractor Supply??
As with other makes that use one-time fasteners, the service Ram manual states: "Do not reuse these fasteners. If removed, a new fastener must be installed and tightened to specification."
My suggestion would be to obtain a factory bolt and washer.
Torque setting are 80 ft. lbs. for A & B-pillar cab mounting bolts. 97 ft. lbs. for C-pillar bolts.

Usually an engineer will determine that in a particular application the torque characteristics of the bolt will have changed after it has been initially torqued. In most cases these are typically Torque-to-yield (TTY) fasteners which stretch after torqueing. In some applications a bolt or nut will have a specialty anti-corrosion material applied to the threads which are defeated upon removal, necessitating a new fastener.Can you explain to me in plain language exactly what makes a fastener a "one time use" fastener. Thanks.
There are only a few places in the service manual that specifically call out to use new bolts upon reassembly. The other that comes to mind are cylinder head bolts. So there must be a reason even if it seem obscure to us.TTY (torque to yield) bolts generally aren't used for cab mounts. You will find them used on parts that have very critical torque specs like heads on engines and such, and they are used there because of the quicker assembly time. In regards to the comment about not re-using bolts, that is pretty common language from the manufacturer for any bolt because of liability reasons.
As far as replacing the cab bolt, don't over think it! It doesn't have to be the EXACT same style bolt if you are in a pinch and need to get one at the hardware store.
