Every so often efforts are made to reinvent mounting hardware. This frequently involved some type of joined bolts with a metal connector that went over top of the griptape, as was the case with U-Bolts and Bridgebolts. There was a Deadbolt version that ran the long way from the front to the back truck mounting hole. Saving on not having to use a screwdriver was a big selling point.
One other method to get rid of that pesky screwdriver was to design a bolt that was pounded into the top of your deck. This is what Thunderbolts were. I couldn't find an ad so I rummaged around in the garage and found the actual bolts to take a photo of. The bolts have two little nubs under the head that are supposed to hold the bolt in place. However, since skateboarding rattles around the trucks and loosens the hardware, this would become problematic when the bolts needed to be tightened. The little nubs would wear away at where they were sunk in and no longer do their intended job. Plus they theoretically weakened the board from the impact of pounding in the bolts. This idea pops up every now and again.
I'm assuming Skully Nuts were just regular bolts. I only scanned the ad because of the cool skeletons.
