    A bit more info on installing insulating rivet nuts. And they are known by many different names.

    Here’s what I have so far...

    99602A430 Nylon Hex Head Screws, M5 x 0.8 mm Thread, 20 mm Long
    99091A153 Black Nylon Hex Head Screws, 6-32 Thread Size, 1" Long
    93495A110 Rubber-Insulated Brass Rivet Nut, 6-32 Thread, 3/8" - 33/64" Material Thick Range

    Now, rivets... I’ve got a rivet gun (came with the car) but have never used rivets, seems it makes sense to maybe order some rivets while I’m at it, is there a fairly generic size I should get?

    Any other useful spares while I’m at it?

    Okay, so the bits and bobs are here. The outer “flange” on the rubber insulated rivnuts looks huge/thick, does that compress when installed? Looks almost 1/8” think or so.

    Better figure out what to do with them.... so I drill a 1/4” hole, pop it in but then what? Does the bolt sqush it up or am I foolishly not realizing there’s a tool I need?!!

    Chris,

    The nut will compress on the back side when bolted in place (see photo). As for the thickness of the flange, you can always reduce the thickness with an xacto knife. Part number 93495A310 provides a thinner flange, however, it is for thinner material (see photo).

    Did you trim yours down? If not did it leave the fender sitting away from the body? As I’ll be mixing the original rivnuts and these I’m concerned about making a kink in the fiberglass.

    I dint trim mine. Used the rubber nuts all the way around (uniform). I also used fender welting in between the Fender and the body panel.

    Okay thanks, I’ll give it a shot this afternoon and see how things go. I guess if the fits not right I can just drill out the other rivnuts and replace with rubber.

    Using all rubber nuts at this point will most likely be the easier route.
