This genuine OEM replacement jam nut attaches to the idler bracket on a tiller. Jam nuts are a special type of nut designed to not unthread or strip out over time. Jam nuts are usually fastened on with another standard nut and then the two nuts are tightened against each other. Jam nuts can be easily identified from a standard nut because they are roughly half the size. Jam nuts can be lost while making repairs because of their small size. If lost, it might not affect the idler bracket immediately, but over time the standard nut may begin to slip or unthread. Therefore, the jam nut should be replaced as soon as possible. When making this replacement, be sure to unthread the standard nut as well and then tighten them both together using a wrench. This replacement jam nut is a high-quality part sourced from its original manufacturer. It is compatible with Troy-Bilt, Yard Man, Huskee, MTD, Ryobi, Yard Machines, and Cub Cadet tillers. This part does not ship with any additional hardware.

This lock washer is used frequently for a number of applications on power yard equipment. The size, 5/16, is the default for many small engine housing and manifold applications. Lock washers are used with machined bolts to fasten engine blocks to the housing of the equipment being used.
