Super Jet what is the bolt size for yamaha start stop switch mount?

[McDog]

I got a sss mounted bilge switch but it didn't come with bolts. The oem bolts are too short. I need to order some today and I am at work and can't remember what size they are.

Go to home depot on your way home and pick up some 10-32 bolts. I want to say those are the appropriate size off the top of my head and they are $1 a bag for SS screws. Maybe pick up 1.5" and 2". If you're wrong, you're only out $2 and 5 minutes.

I know they are metric. I compared them to some bolts I had. They a smaller than m6 too.

m5 x.8 x 25mm long

Except I need 50mm long with the bilge switch. Thanks!!

45/50mm is the correct length.

And you need bushings.

 

[Pablo]

Yes to the bushings.

 

[McDog]

Does that mean you have bushings for me or that I need them? How long are they?

I have good news for you... An M5 screw has the a diameter of 0.190" and a #10 screw has a diameter of 0.197". #10-32 has 32 threads per inch which is 64 threads on a 2 inch screw. An M5x.8 has a pitch of .8mm per thread which over a distance of 2 inches 63.5 threads. That's basically the same thing and for a screw going into plastic, I think you're fine. Maybe on a precision metal on metal, it won't work... Just trying to give you a local route to get these parts as opposed to ordering them.

 

[McDog]

True. Price was stupid for bolts and spacers from mcmaster.

Sure, I have the brackets for $20 with the machine screws and bushings.
