Product Name: Disk Washer
Dimensions: 12mm*1mm Thickness 1mm, gasket inner diameter 10mm

Note: If you have a two-piece sprocket wheel, you need to change it to a single disc. You need to add a washer to the disc nail (the sprocket wheel screw) to fasten a piece of sprocket wheel.
Dimensions: 12mm*2mm Thickness 2mm, gasket inner diameter 10mm
Uses: When the double disc nail is used to install a single disc, the male nail will be too long, so that the wrench can not lock the nut, and the gasket can solve this problem.
