Early (1909-12) gas generator mounting bolt. Note that there is no square under the head, the head is not slotted, and the shank is crowned. Paint black for late 1911 and '12. Sold in sets of 3; correct raven finish nuts included.
I think I see a little key to keep it from turning. Is that right?
Looks good. How does that work out with the holes that were punched in the runningboard? My 1910 runningboard holes were punched at the factory, from what I've read here.
No; there's no key or anything to hold it. Sort of like the early hub bolts that had no shoulder. You keep pressure on the head while tightening the nut, and then friction takes over. Most likely the running boards were punched for the generators, at least by '10, or as soon as Ford became the primary supplier of lighting equipment.
Here is a set I made.
RV's are perty-er.
