shear pins are normally just a mild steel, the idea is for them to be softer than all the other "stuff" so if there is a jam up it is the shear pin that breaks and not the gears being wiped out.
Thanks for the reply. That is what the trailer repair shops said. My problem turned out to be finding a pin with the right dimensions. I used a dowl pin that was pretty close to the right size, and it seems to be working . I got a couple for safety. Thanks.

ya a lot of times they will even use brass dowel pins as shear pins. the main idea is the shear pin is there to protect the rest of the system from damage. it has to break before the other components or it isn't doing its job, and instead of a 10 buck repair you have a 1000 buck repair. you need to find out for sure what the drill rod was made of, but for now just go to a metal supply store and ask for a chunk of mild steel drill rod the length you need. might have to buy a foot of it, if so cut it into a few shear pins so you have spares. I think I have a bag of 20 shear pins for my snowblower in the shop😁
