why not the option of drill and tap 5mm metal threads? I have used pop rivets in the past and have torn the whole track off and that was MK1,. I hate to see 2 up cos that's a lot of force. Self tapers should not be used in metal or in the marine trade. They are not reliable. the heads break off and when you want to take them out the will break and you have to drill the out making a bigger hole. I deal with this crap everyday day.
couple of reasons....
1/ don't have the countersunk 'bolts' on hand
2/ don't have a 'tap' that small, the smallest taps I have is 8mm or 5/16th Whitworth.... = overkill
agree on the self tappers, the odd one is after all the years the track has been screwed to beam only 3 have broken.... the 3 that actually bent and subsequently cracked the track. All the other self tappers were in good condition and came out without any major dramas or effort although there is some corrosion of the alloy adjacent to the holes in the beam.
At the moment as far as the rivets go, I'm happy to do the try it and see how she goes. And as I've said I think most of the issues with the rivets is a pan head in a countersunk hole..... time will tell
