Small parts go missing all the time. Should you need extras for your holders, these are the nuts and bolts.
This set will not work with original eLane nor the original Geo frame number plate holders.
Five 4mm socket head bolt
Five #8 nylon lock nut*
Nylon lock nuts differ from a standard nut in that they have a nylon insert secured within the nut. When you install the nylon lock nut onto a bolt the nylon insert wraps around the threads and locks the nut in place. The nylon ring creates rotational resistance preventing loosening.
