Jacques Bernier at Hobie Cat USA, with help from Jeremy Leonard of Surf City Catamarans www.surfcitycatamarans.com, followed up with answer to my question:
"What is "thread-size" for 60450000 Tension Screw?
I had to drill frozen Tensions Screws out on my Hobie 21SC rudder assembly. Would like to "chase" (clean) threads before replacing with new Tension Screws."
