Hey Ron, Fare Dinkum (spelling?) Pianotek has agraffes in 1/4"-36, 7/32" and Metric (32) and two spacing options for bichords. I've also used agraffes from Steinway NY without issue. What is your spec for the holes? These measure .082" diameter with the Steinway part being just slightly more snug (at least on my samples).
