Shear Bolt (5/16-18 X 1.5'' Lg.) 710-0890A

This is a shear bolt, also known as a snap-off bolt. This is a fastener designed to break under a specific amount of pressure and protect the machine it is installed on from that excessive load. In lawn equipment, the shear bolts typically connect the auger or blade to the drive shaft. Therefore, if the bolt snaps, the auger gets jammed and cannot rotate so that it will not damage the rest of the unit. This bolt has a diameter of 5/16 inches, with 18 threads per inch, and is 1.5 inches long. To remove the shear bolt from your machine, you need to turn the power off first. With pliers or a wrench, grip onto the broken end of the bolt and twist it gently out of its hole. If it is stuck, you may need to coat the bolt with a penetrating oil or tap the bolt out with a mallet. Since this authentic OEM part is sold individually, refer to your instruction manual so that you can purchase the correct number of bolts for your machine.
