What size shear pins do I need?
Brass 1/4″ shear bolts are most commonly used on smaller, entry-level snowblowers. Black 5/16″ shear bolts are for larger mid-grade snowblowers. Silver 5/16″ shear bolts are the most durable and are used on professional-grade snowblowers.
What grade bolt do you use for a shear pin?
Registered. Normally shear bolts are Grade 2 and there is no soft grade #5 as it is either a grade #5 or not.
How tight should a shear pin be on a snowblower?
It should be a locking type nut and all you need to do is snug it down to where it contacts the auger sleeve and stop there. Don’t snug it down to where the spindle turns with the shaft.
Are all snow blower shear pins the same?
All two-stage snow blowers have at least one shear pin on each side of the auger gear case. A shear pin is different from a regular bolt because it is designed to break, or “shear,” which in this case is a good thing.
What is a shear pin made of?
Material. A shear pin could potentially be made from any material although metal is the most common. When making a metal object for a mechanical application, an alloy and tempering is usually selected to make the construction resistant to damage.
What is a snowblower shear pin?
A shear pin (also known as a shear bolt) is a weak bolt that connects your auger to the auger shaft. These jams that interrupt the auger rotation cause the shear pins to break, releasing the auger shaft from the auger. While this stops the auger from rotating, this also prevents damage to the snow blower gearcase.
How does a shear pin break?
If a large object gets wedged between your augers and the housing, the pins break as designed to protect your auger gearcase from incurring damage. These jams that interrupt the auger rotation cause the shear pins to break, releasing the auger shaft from the auger.

Why is my Auger on my snowblower not spinning?
If it feels like your snow blower is pushing snow rather than processing it, or if you see snow building up outside either side of your auger housing, you likely broke a shear bolt. When the shear bolt busts, the auger shaft continues to spin, but the auger itself isn’t spinning. Without a spinning auger, snow isn’t ingested or thrown.
