After my recent bout with broken and sheared off screws on Penn reels, caused by corrosion, I thought I would consice some information and post for everyone. I had to drill and tap 4 different size threads on various Penn Reels. Here are some Penn part#'s and the thread/pitch sizes associated:
Penn Part Size Tap
110-50 5-40
31-50 8-32
38-50
34-50T 1/4 - 20
32-14ch. 5-40 uses #38 drill bit
16-60Ch 6-40 uses #33 drill bit
32-17 5-40
63-30T 8-32 uses a #29 drill bit
Please add others as you encounter them.
man, i'd hate to be the guy that came up with all of these the hard way!
