I am putting an order in for a Thumb screw that replaces the security screw and PIA screw driver that comes with the Zumo mount. Screw fits the model 450 and 550. I have a couple and want a couple more for other bikes. I will be ordering for others and will save $2.50 shipping. Will divide between total or as close as possible. No pennies.
