AL 2024 T3 or T4 has a tensile of 68000 psi a yield of 47000 and most important (to us anyways) shear strength of 41000 psi. I have no idea if this is to much for these winches or not. So I am probably going to go with AL6061 T6 which has a shear strength of 30,000 psi. You can buy a 5/16" 3' section for $2.26 at Reid supply company P/N mes-434 . This beats the heck out of the $3.50 per shear pin price.( I don't mind cutting my own.) Now, this info was relayed to me by a co worker. It being the weekend I have not been able to verify this myself. I hope this accurate and helps all of us that are in the shear pin dilemma. I will soon see. By the way actual size may be 9/32" but would it hurt anything and not be easier to drill out the pto shaft to 5/16" than it would be to turn down 5/16" stock to 9/32"? Seems like 5/16" material is a little easier to find. Just a thought
