Chassis bolts

If you are installing a hitch on your truck I suggest getting a set of bolts from Reese or other hitch manufacturer. I re-installed my old hitch on my new truck (2006 2500 to 2014 2500) and it required new brackets and bolts that are specific to the vehicle. The bolt kit came with square washers and the bolts were carriage. The square shoulder on the bolt engaged the square washer. The washer kept the bolt from turning.

I believe the poster is referring to a wheel stud type bolt. Round head with splines under head to grip frame without access to inside frame rail to hold with wrench. Something like This Maybe also called Knurled bolt. Best bet is to go to automotive and match up if you have one for show and tell. Randu

Any idea on what you call the wire you thread onto the bolt then feed it through the chassis to the fixing point and pull the bolt through?

Serrated flange bolts. Check with the manufacturer's website, they all have exploded views with descriptions.

Not sure if this is what you are referring too or not. A quick google search came up with this product.



This company calls them Serrated Flange Locking Fasteners
