Unusual Screw Thread May Be Cycle Thread
By Peter Ravenscroft
[ Ref. 110411 MMDigest, "Seek Unusual Metric Size Tap & Die"
> Does anyone know of a source for an M4.5 x 0.90 tap and die?
Having gone through all my books, I have come up with the following:
I think it is a cycle thread, 3/16 inch x 28 threads per inch, as
near as I can work it out to. They are available from Tracy Tools,
http://www.tracytools.com/ They cost around £3 but Tracy Tools have
a minimum order of £10.
