As mentioned, I am using tapped aluminum hole with steel bolt, thus I need longer length of engagement to ensure bolt will fail before nut is stripped out.
My question is however, when determining the maximum load that the nut can handle, should I base nut and bolt shear areas on the Le from...
Corypad,
Please disregard my last post. I found a mistake in my calculation and am re-evaluating. My nut shear area did not increase with the coarse thread.
Sorry,

Cory,
Thanks for the formulas.
I have an application where some tapped 3/8" UNF holes in an aluminum plate got stripped out by grade 8 screws. My first thought was to increase tapped hole size in aluminum to 1/2" UNF. I performed the calculations, and for fun I performed again using 1/2"...
This is a late follow-up question to thread725-35222. I was wondering where values are obtained for dimensionless nut thread bending factor C3. The original post was for a steel to steel bolted connection, and recommended using .897. In my case, I have a steel bolt (grade 8), and 6061-T6...
