Worm gears on a manure spreader

I'm surprised that regular bolts work. They usually deform and often bugger up the system. Grade 5 bolts shear nice and clean and work much better. You might need 5/16 though because grade 5 is stronger than regular grade.

Depends on the Class of the bolt. We used to tow Aircraft in and out of the Hangars using a #10 size grade 5 (IIC) bolt as the shear pin in the system. Didn't keep any souvenirs, but am willing to swear to that it was a fairly basic, 3/16" bolt of no particular significance! We all carried a couple spares in our pockets!
