Thank's dean,
Seem's there are a wide assorment of different pin's used.
I have considered a shoulder or aircraft screw .
My thouth's are these will be a bolt & nut less thread's tru prop an shaft,
for a less chance of pin loss.

having been a toolmaker since 1956, my knowledge of dowel pins is that they are case hardened and ground on the outside but soft in the center. people that I have seen use them, they always broke, sometimes sitting on the ramp. grade 8 bolts work well by cutting off the head and threads. the very best thing is a shackel pin from Aircraft Spruce and cut off the head with carborundum wheel as they are too hard to saw. just my humble opinion.

Hello" Mr Bill

I am considering aircraft clevis bolt's.
Looking at AN 24-26, not sure how they compare to the grade bolt's.
These have a low prorfile head an are short treaded .
Wondering if these mite make a good pin ?

thank's mike
