Shear pins are designed to protect your mill.  Always keep a stock on-hand!

The Shear Pin is mounted at the back of the pellet mill and, under normal circumstances, should remain still throughout the pelleting process.  Shear pins are designed to break under a predetermined force to PROTECT other parts, acting like a safeguard. 

 If the Shear Pins are compromised by dents or scratches, they will not work properly and movement will happen causing problems with the pelleting process.  This can result in the Shear Pin either breaking prematurely causing downtime, or not breaking at the specified point, possibly causing catastrophic damage to your mill.
