[Healeys] lost parts

[Curt/Nancy Arndt]

Alan and Fellow Listers,

Technically speaking, yes and no.  By definition, *Whitworth Fasteners* are
those fasteners that have a 55 degree angle of the threads.  As such the
five basic Whitworth fasteners (there are several more not worth mentioning)
, they include...

BSW - British Standard Whitworth
BSF - British Standard Fine
BSP or BSP(P)  - British Standard Pipe or British Standard Pipe (Parallel)
BSPT- British Standard Pipe Tapered
BSB - British Standard Brass

Just because it doesn't have Whitworth in the name , doesn't mean it's not a
Whitworth thread form.  This a common misconception.

Cheers,

Curt
