I have a snowblower with the typical shear pins on each side of the front
augers. I usually use mild steel capscrews, but I've been having them
shear more often lately, in what seem to be only moderate loads.

Have you actually *found* the sheared bolts? I thought I was
shearing them on my snowblower too, until I found one that
was intact on the ground - sans nut.

They were vibrating loose. The last ones I put in with locktite,
and they're still in place.
