Source for list special threads used

[Mike in Mass]

Good morning, all!

I've tried searching the forum but haven't found a link to this topic. Can anyone point me to a list of the special thread pitches HD used on the Panhead, and their application? I have taps and dies 5/8x18, 3/8x20, 3/8x24, 1/4x24 plus most all of the standards.

Any leads greatly appreciated!

Spare Parts Manual, 1941-54, pages 207 through 213 under "Misc. Listings are hardeware items (cotter pins, screws and bolts, washers, nuts, rivets, steel balls and grease fittings. These are listed by Pt. # with a discription of each. Example, Pt # 8095, 1-20 N.E.F. x 3/8 x1-3/8 hexagon nut. This is not all inclusive, but covers the years 41-54 which of course is only the early Pan years. Also you will probably have to convert some of these #'s to the new Pt #'s which started about 1950 (just a guess). Hope this helps ya....bosheff
