I just received my package of 5 fasteners and can confirm they fit. The shaft is about a 1/4" longer than the OEM. I also ordered the fastener/washer tool for $3 which is a good idea.

 

Hi guys,
This happened to me as well, and all the above info has been great in helping me source replacement Loxx snaps.

I wanted to share that I actually found them for a decent price ($20 for 2) at Guitar Center. Ordered them online and free pickup in the local store. And if you sign up for their emails, you get $5 off your first purchase, so $15. The ones from Guitar Center were actually shallower than the Honda one, but that wasn't an issue for me since I only need the "backing plate" part of the Loxx fitting. If you are in a pinch, I think you can use the shallower Guitar Center Loxx, but then you would have to really force the nut on there.

Here is the item number at Guitar Center:

Loxx Strap Lock Set Black Chrome
