Bolts, Rivets, Fender Washers, Wellnuts?

I'm installing a 6" hatch, a couple of cleats, fairleads, etc. I have stainless bolts, fender washers, and nylon lock-nuts. My question is: will the bolts, fender washers, and lock nuts (w/ silicon) be enough support for everything I'm installing or do you think that it's overkill? I don't have any pop rivets but could wait to install everything for a couple of weeks if you think that there is one system that is better than the others.

I checked over the other topic threads and saw a couple of discussions that mentioned rivets and wellnuts but nothing definitive. Thank you for your feedback.

Everyone has their favorite methods but I think the general consensus last time was to use SS hardware whenever you can reach inside. If you can't reach, some like plastic expanding rivets, some wellnuts. More personal preference than anything else.

Enough for support? Over kill?   Ahhh,, Yeah.

 But MUCH better to err on the side of the latter. Jay said it exactly right. SS hardware/fender washer/nylock nuts where you can reach them. If you can't get to the back of the fitting, I think I'm going with wellnuts or rivnuts over rivets as I have had rivets pull out in the past. But I tend to push things a bit hard  (the rivets failed on the flush mount rod base when I used the downrigger,,,,,,on an extension ) What a surprise huh?

If your going to permanently mount an accessory use 3m 5200 or 4200 as a sealant. After that cures, it won't come off. Just make sure the fitting is where you will always want it and does not interfere with your stroke or scooting about on the boat.

Thanks, gents! I feel better now about tearing into my kayak.

On high stress items such as anchor trolley and cleats, many also use a plastic backing like a piece of plastic cutting board.

Whoa! That's pretty serious stuff but I can see what you mean. I take it you glue the entire cutting board to the underside of your yak?

I have some extra slats from plastic blinds that would do pretty well for that job (I think).

No need to glue the backing plate on. It will be held in place by the hardware.
