I think these bolts are pretty cool, they definitely have a unique look. I wish they came in 6” & 8” length and 1/4” as well. We’re restoring a 1925 Durant Motor Star Truck. Its body is 80% oak, build by a wagon company from Flint Michigan. We plan to use these where the tail gate bolts need to sit flush into the steel plates on the tailgate and across the floor of the truck bed. I love all this unique period correct hardware! Keep up the good work, the quality and selection is superb.
