Reassembling the brakes on my tractor, and found this. I’m glad it came out in one piece when I took it apart. The bolt size is 7/16 x 14 USS. My friend spotted the hourglass shape, and I put the pitch gauge against it just for grins. 
Over torqued!

Typist error in some maintenance instructions led to us trying to torque some hardware to a factor of 10x design torque....When an 1 5/8's bolt yields.....
I'd bet that's fairly noticable

Was quite exciting. We eventally went to a softer seal material that worked better and it let us drop the required torque by a factor of 10. Went from a two man torque job to a single guy with decent strength.

I did that one time (only one) on a rocker arm bolt for an oldsmobile. I could tell it wasn't going like the other ones, fortunately. I had used STP for a thread lubricant on it and that was just way too good.
P.S. This was with a torque wrench

When I was working on a Flag Pole, while standing in the basket of the Knuckle Boom at full extension, i used the longest "Cheater" i could find to take the upper pulley loose from the pole. I did not want to have the rusted threads break loose as i was straining with a short wrench.

The less it hurts when it does break loose too.
