Hey aFITcianados! (see what I did there?)

I need help identifying the right replacement hardware for the undercarriage/splash guard. I seem to be missing some and it either fell out, or wasn't replaced by the Honda maintenance team the last time I had it serviced back in September.

I'm specifically looking for the proper size screws and U clip (I think they are called) for connecting the difference parts of the splash guard together.

Additionally, there looks to be a rivet/clip system (three in total) that connect the splash guard to the front fender. I tried using the regular rivet/clips in the one missing slot, but it didn't fit or stay. Is it correct that this is a different size rivet/clip and, if so, any help finding the right one?

Please see photos for reference, and thanks in advance for any assistance you can provide.

 

You should be able to buy sheet-metal style captive nuts and sheet metal screws that fit into their holes, in any hardware story. Alternatively you could make the captive nuts yourself. With a sheet metal shear cut a piece of galvanized steel sheet metal into shape, and bend it into shape. Drill a pilot hole for the sheet metal screw. To make things easier, you can get sheet metal screws with hex heads instead of Philips head. #8 screw, #10. I'm not sure. As far as the plastic push-pin rivets, the ordinary 2-part kind that is used in the engine compartment to hold down the plastic trim there, worked just fine for the 2 pins at the rear of the shoud. You don't need the original kind that has a Philips slot in it. The plain push-in pull-out type works just fine. Just make sure it is the right diameter for the hole in the plastic shrouding that it goes into. Just push them into the hole. The inner piece that goes through the hole expands at the far side of the hole, after you push it through the hole. To remove it, you just put a pry bar around the head, and under it, and pry the pin out. You can buy them, aftermarket ones, on amazon or ebay, from US sellers, by the score, for very little. Plastic retainer clips. They have 2 parts. I think I paid like $5.00 US for 20 of them. Temporarily you can pull 2 from the plastic trim in the engine compartment. The trim in the engine compartment should stay in place, while you wait for new rivets to arrive.

I found this. I think these should work. The one's I have look a little different, but they are the same size, 10 mm in diameter. Note it is from a US seller – you'll thet them much faster probably. I've also just found this. My center post looks different, but as long as they are 10mm, and as long as the "wings" spread out when you push the center post down, they should work.

Below are the clips I used for my undercarriage on my 2017 fit. Only modification I made to the fastener screws is I clipped the ends on them to make them easier to remove. This way I'm not breaking the clips each time I want to remove the undercarriage.

 

Sorry for the late reply other life things got in the way...

However, YOU GET A GOLDEN STAR! This information is exactly what I needed thanks!
