Thread Size for Dana 70 Diff Cover Bolt?????

I know that the bolts are 3/8X16, but are they coarse or fine thread?

Thanks in advance.

3/8-16 is a course thread.

That just made me realize your correct. 16 threads per inch=course. Correct?

3/8-16 = course
3/8-24 = fine

In my line of work, I deal with bolts just about as regularly as an employee of fastnal,

Which I'm not sure why someone argued with me on that other thread about odd sized bolts... I HAVE SEEN bolts with less than 2.5x the diameter engaged rip right out of a tool.

Although I reckon he thought I meant with a nut on the back, I was referring to a bolt in a blind or thru hole in a component.

^Yup that’s what I meant.
Arguing? Just wonderin. Because in structural steel work, bolted connections in full tension, shear and slip critical connections, 1 full thread past the nut gets full development strength and nuts are generally only slightly taller than the bolt diameter.
Why is the criteria different in a blind hole etc?
Have never analyzed or engineered the shear strength or yield strength of threads.

No hard feelings friend! Lol.

I assume when you're getting into something structural where a full thread past the nut is used, it's more of a concern with sheer strength.

In my line of work, you run down 2.5x the diameter for tensile strength


Also because if you don't run enough threads down, the tooling can quite literally be ripped out of the cold rolled steel die shoe.

Crazy ****.

I need to stay off this forum while I'm drunk, I end up acting like an ass sometimes.
Sorry buddy @Grit dog
