Looking for the screw size n thread that attaches the engine baffles. I believe 12 screws are needed and 3-4 larger screws (behind cyl #3 and #4)
Thanks
Thanks
Were those course threads and not 1/4-28s? Can look tonight if definitive answer not provided by then.
1/4 x 20 IIRC.
Typically course threads are always used in castings such as the cylinder heads and crankcases.
Why the recommendation to buy Grade 8? Can't be load, is it plating, or??
Where can I find a chart on the MS screws to determine what the numbers mean? MS35206-281 is for 1/4”-20, 281 is the length of 3/4”. So what would the MS number be for a 3/16” dia screw and what would be the thread, 20 or 24.
