Yes, having the wrong sheer pin or bolt is like having none. Look up the catalogue number of the OEM one and find its spec, or maybe you still have an OEM one. Then order or take the sample to CT or Amazon to order replacements and always have a few spares on hand

Yes. Sort of. I haven't seen specs published for a specific snowblower to show the torque required to shear the bolt. You could figure it out with some work and make your own but if you are breaking enough to make that worthwhile, your time would be better spent elsewhere (stronger blower or more time cleaning up frozen newspapers before blowing).
I have never had a shear pin break and my snowblower is 30 years old? The big one on the tractor doesn't have shear pins the auger is welded to the shaft.

I have broken one. Trying to cut back the giant frozen tower at the corner of the driveway to relieve the corner and increase visibility. Crashing a snowblower into an ice tower works most of the time but not all of the time.
You're lucky.
Mine has a Walterschied shearbolt clutch that relies on a single M80 bolt. Attempting to work in wet snow like we just had is absolutely hopeless. Thankfully the tractor has a loader.
M80? 1000hp blower?

I haven't broken a shear pin in a while, but I was on a streak with my dad's Craftsman that just about every other time I used it I broke a shear pin on it.
Both of the neighbors had their water shutoffs in the middle of the driveway, which were high enough to catch the auger. You'd think you know where it was in the drive way and avoid it but hit it anyways. Or ramp up a concrete curb and drop the auger on it. Last time I broke one was a chunk of slush that had turned to ice off of a car in the driveway.

The one time I broke the shear pin on my 30 year Craftsman was about 10 years ago. I ran over the slightly raised water shutoff valve, ripped it out and it went through the discharge chute onto the lawn. Dented the auger housing and tore the plastic chute up. Replaced the pin and all was well.
My rather monstrous 45" Cub Cadet had never broken a sheer pin and out of curiosity I looked up the specs and found the ones in it were a size too big (from previous owner) and I've been using it for years. They had to be hammered out and I put the correct size in only to immediately start breaking sheer pins on normal light snow where I shouldn't be breaking them. I drilled the holes slightly larger so that the next size up pins would slide back in. Guess the previous owner was on the same train of thought as me. I don't recommend doing this btw but I'm shopping for a new one anyways as this one has been great for 15ish years but is starting to need more maintenance and will likely need new friction disc and wheel, probably should replace fuel lines, etc.
If only it would fit....
This is an M80 bolt.

Neighbours snow blower fires up and dies.
Starter doesn’t work but it started with the pull cord, sputtered, and failed.
Carb looks clean.

Took it apart again and the old fuel line disintegrated from old age.
Where is the float needle?
It was in another spot as I took it out.
