How many threads are in a 3 8ths 24 UNF tapped hole that is 32 thousandths deep?
A 3/8ths 24 bolt has 24 threads per inch (TPI), and a 32 thousandths (0.032) hole that has been completely bottom tapped for 3/8ths 24 fastener will have 24 x .032 or 0.768 threads in it. And yes, that isn't even one complete turn of the bolt before it bottoms out.
