Screw size for Hobie Rudder Handle

Anybody know the size of that little machine screw that holds on the rubber/plastic rudder control lever on Hobies? I can't find it online readily.

If the rudder handle is the latest one where the screw goes down into the crank (under the Hobie vinyl sticker)....the parts catalog P/N is 8030126....description is screw, 10-32 x 3/8 FLNG BTN HX @ $.89
Hope this helps.

I put a 1/4-20 eye bolt into my front rudder handle to allow a tiller extension so I can sail from the trampolines.
