I'm sorry but I only had a metric micrometer to hand.

Here's my LP90 flex. The head measurements should be the same.

Edit: just realized I added one measurement twice and left one out.

Just adding a recommendation to the list here. I used my Proto 90t flex 1/4" you're asking about yesterday on a Miata rear shock top hat nut where my Snap-On extra-long 1/4 72t had too much arc swing to grab the next tooth. The extra teeth in the Proto worked perfectly.

FWIW, the best prices I've found are at circlesupply.com. I liked the first short 1/4 so much I bought 3 more (so far!) from them.
