Washer, nylon 5/16" (EACH)
(0.3125" I.D. x 0.75" O.D. x 0.0625" or 5/16" I.D. x 3/4" O.D. x 1/16" thick)
Made from real nylon, not cheap plastic junk!
Used between rivet cap and the grommet on the hitch. This will fit 1/4" cord (our rubber cord) or 5/32" cord (our nylon cord) or our new weed eater 0.170" cord! This makes the brass grommet last much longer. Can also be used between rivet cap and metal swivel to help those parts last longer, but the most important area to use it is the hitch end of the cord where most of the swiveling takes place.
