Fits Reels (23-220 handle nut):
220GTO, 230GTO
NOTES: Threading measurement is unusual
Per one of our customers:
"I have identified the thread as M7 x .8
This is quite an unusual size even for the metric world.
DOES NOT FIT: M7 x.75 is quite common, but doesn’t work or fit our Penn fastener! Someone jammed a hardware store fastener in the reel I’m fixing.
I have found a repair tap believe it or not right here in Australia at a small company that actually manufactures them!
Apparently modern Harley-Davidson bikes use this size for some applications too.
Hopefully this info can help someone else. - John B.
