Honda ca77 petcock screws

Post by twiggie55 » Fri Aug 28, 2009 5:29 pm

I'm looking for a couple of petcock screws . When I ordered them from the dealer they sent me replacement screws and they were to long and the width was wrong. Here is the part number it said in the manual 93500-06025 but they sent me 93500-06025-0A. Can somebody help me?

Kirk, do you know which screws are used in a 1964 CA77, and whether they are pan head or flat head?
Thanks!

Just run a ISO tap through the holes and use a standard ISO screw.

Aren't some of the smaller JIS a different thread pitch to ISO ?

Very slight difference in pitch. The first 4 or 5 threads will work without the tap. A ISO tap goes through easy and holds well. I have done this with a numbers of screws on my Dream. Even did the shock mounts so I could use stainless ISO acorn nuts.
