Stens Snow Blower Shear Pin Bolt

A shear pin is designed to be the weakest link in your snow blower's auger system. If the auger hits a solid object like a rock or thick ice, the pin snaps to prevent the engine or gearbox from sustaining expensive, catastrophic damage.

These pins are compatible with many two-stage snow blowers from brands like Ariens, Jacobsen, John Deere, and Stiga. However, you should always verify your owner's manual for the specific part number required for your model, as dimensions like the 1/4-inch diameter and 1-7/16-inch length must match exactly.

No, you should never replace a shear pin with a standard hardware store bolt. Standard bolts are often too strong and will not break when they should, which can transfer the impact force directly to your snow blower's gearbox or auger shaft, leading to costly repairs.

This package includes four shear pins. It is highly recommended to keep these on hand throughout the winter season, as they are intended to break under stress and will need to be replaced periodically.

Replacing a shear pin is generally a straightforward maintenance task that most owners can perform. You typically just need to align the holes in the auger shaft and the auger blade, insert the new pin, and secure it with the appropriate clip or nut.
