Thanks Alley

I got a m6 x20mm screw and although it fits into the drain its head does not fit in the hole. i put loctite on it and have yet to attach it to t he bike and turn it on. my question though is what other methods do you suggest in dealing with this issue? should I clamp the hose? seems easier than that flipping screw falling out at random

An easy fix would be just to chop it off, and install a 1/4" shut off switch/petcock... It would function the same as your screw and will fit the existing hose....

You could also just snip it off,and a 1/4"m x 1/4"m adapter fitting and put a plug/cap on it. Or, screw a bolt in it and then clamp the hose.

Trim the new screw length

Hey Borg,
Its not the length that is the problem it is the width of the head. i can't find a screw with the right head size. If Rich was here he'd go to town with this on lol.

The drain screw on mine is 6mm x 25mm. The head & threads are both 6mm.
