Hello Everybody!
I recently got a Stanley 50 combination plane but unfortunately two screws are missing. The ones that hold the depth and beading gauges in place (marked on attached picture). If any of you could provide me with measurements or technical data on these I’d be extremely happy!
I need to find out the thread size (TPI probably) and the screw diameter at least.Thanks in advance!

You must be logged in to view attached files.Presumably your plane as shown in the picture is British-made. (American-made variants of the same tool should be the same dimensions but may have unified threads), in any case the measurements are in Imperial (inches) because that is what was used when the plane was made.
In the UK, threads in machine bolts were either Whitworth (Whit) or for finer and smaller screws British Standard Fine (BSF).
Vital statistics are:
Total length: 5/8”
Length of thread: 3/8”
Head Dia: 1/2″
Bolt Dia: 3/16″
8 threads per1/4″, therefore 32 threads per inch.The bolt in question is 3/16” BSF.
Here’s a useful link to sizes: https://en.wikipedia.org/wiki/British_Standard_Fine
I hope that this helps. Spares screws can be obtained, but are expensive, hopefully you still have the associated depth stops.

(I forgot to mention this, yes my plane was made in England.)
These measurements were taken from an actual British plane or from a catalog?
I have the depth stops only the screws are missing.Thank you again for the technical data!
GergőThey were measured from my own plane which is identical to the one in the picture. I guess that it dates from the 1950s / 60s.
Amongst others, Whitworth and BSF threads of all sizes were universal in British engineering from the start of machining in the 19th C but are obsolete now. Even so, tooling is still available…. taps, dies etc.
You may find replacements on the spares market, depending where you are, alternatively they are not difficult to make if you know someone with a lathe and the tooling.
Good luck

Thank you very much for the detailed information and for the background!
Best regards!
