Hillman 126833 #8-32 Nylon Insert Lock Nut-10/Pack

Nylon insert lock nuts are used where heavy vibration is found and when a tight frictional fit is needed. This nut must be installed and removed with hand tools.
Spin freely until the nylon washer engages the threads of the mating part
For the locking action to be effective, the washer must contact fully formed threads so several threads of a standard bolt/screw should extend beyond the top of the nut
Zinc plated for moderate corrosion resistance
