I have a pair of Look PP357 pedals with a 9/16 stamp on the spindle. However, that size wrench won't fit. I measured with a caliper and sure enough, 15mm. What's the deal? Anyone else ever notice this? Are they all stamped wrong, or just mine? Or are they all stamped correctly and mine are just too big? Hmmm, so confusing.

It seems likely the 9/16 is the thread diameter. The common pedal thread for the three-piece type cranks is a 9/16" x 20 tpi. The pedal wrench flats are typically 15mm, plus or minus quite a bit.

Ahhh, thank you for clarifying.
