Threads overview

hi

does anyone have an overview of all the threads on a wm20 rigid frame also girder and eg rear stand? I ve searched the www and some books because I need to reassamble my BSA but a lot of bolds are missing and/or internal- external thread are found to be damaged in some way....... I have to be sure I use the correct threads, taps, dies and bolds

thank you
Arnold

Re: Threads overview

Hope this is helpful: Use the Draganfly website for reference; many fasteners identified in their web catalogue are denoted by size and thread.

The majority of fasteners on the M20 are 26tpi.
