Review on Motorcycle Hardware DPWM12 20 50 Drain Washer by Andrew Gomez

(DPWM12.20-50) M12 Drain Plug Washer from Bolt Motorcycle Hardware I use it with the drain plug and also some ultracapacitors to connect washer the ones i play with, 12mm is the size of the caps studs on the negative and positive ends. My shipping cost as of April 25, 2017 was $14.45 including sales tax. I like them well enough for 4 stars at the moment.
