Bolts under the rubrail
« on: October 04, 2021, 01:11:04 PM »

I am replacing the rubrail and found a number of 10-24x2 machine screws protruding above the surface.  Does anyone know their purpose? Are they part of the hull/deck joint? The new rubrail is unlike the original and wants to sit flat on the surface.  I can counter sink the backside of the new rail if necessary but these screws are a mystery.

The factory drawing only shows thru-bolts. Screws hold on the aluminum channel. If you have screw pounty threads sticking outboard, I have no idea.

There is quite a bit of info on the C36 website on how to deal with this. They  can be accessed under the inside trim alternatively cut around them with a circular cutter and only replace the screws when fitting new extrusion.
