": Looking at the bolt torque calculator, no length of engagement is considered. Isn't that critical?: The torque given for a 10-32 in aluminum is 13.8 in/lb, but at what length? Is the bolt considered to be aluminum too, in that calculator?"In general, the fastener torque design does not consider thread engagement. I believe most folks assume 1.5D (major) thread engagement when designing for a fastener fit.I believe one could calculate a fastener torque while considering actual thread engagment.Check out the thread stress area calculator here on enigneers edge. With this calculator you can determine actual thread stress for a given engagement.
