How tight DO you tighten well-nuts? I'm from a background of "tighten till it stops" and actually had to modify my bar ends after pulling the nuts through the rubbers :naughty:
Anyways, I don't want panels falling off, but tightening these things and watching them expand, but not resist much more is frustrating. At what point can you stop and feel safe that what they're holding isn't going to fly away?
Well-nuts work by having a brass ferrule draw a rubber sleeve toward a fixed point. This allows the rubber between the ferrule and the fixed point to expand and become a larger diameter than the hole through which the well-nut is inserted.
Over tightening a well-nut will crack the rubber and make it pone to failure as well as make the stiction difficult to overcome when removing the fastener.
To see how one works, pull a well-nit form its location, hold it in four fingers, insert the fastener screw or bolt and turn it until maximum expansion is reached. You will see that torque is NOT your friend with well-nuts.
