I'll take your word for it, still, thats a pretty long pitch for a prop of such a small diameter.
Don't take my word for it when a pic is worth a thousand words
FWIW i use this on my Jett 60LX turning it at 21 grand on a Diamond Dust, i also use the 8.75x9w at 19 grand, all the 'Pylon' series APC props have a D hub which is much thicker then the regular 'sport' APC props so they handle the high RPM without slinging a blade.

EDIT: found a package for the 8.75x9w and added the pic
