Matt,
Sorry I haven’t followed up. I measured the screw, which has a major diameter (the outside of the thread) of .177 inches (about 11/64) and 4.32 mm, which matches a #9 machine screw with 32 tpi.
Unfortunately, nobody seems to make a #9 machine screw since the sizes got standardized. Only #8 and #10 sizes, neither of which work. I’ve been searching for a source here and there when I have time, but no luck.
9 February 2015 at 8:48 pm #124502I haven’t got a 45 plane so I can’t be much help.
Have you had a look at one of these? Invaluable for finding thread sizes.9 February 2015 at 9:18 pm #124503Thanks, James, but I ruled out Whitworth threads. The diameters and pitch count don’t even come close to Whitworths.
Unless someone can find a source of 1/2″ 9-32 machine screws, I think we’re out of luck.
9 February 2015 at 10:10 pm #124504Could be a cycle thread (BSC) 7 swg rh, about 2/3rds down the first chart. The dimensions seem pretty close to yours. I’ll do a bit of digging and see if I can help.

10 February 2015 at 1:22 am #124509Thanks for taking the time to reply Derek, and James. Are we talking the same M8, M9, M10 etc. commonly available in the UK, or does the US use a different system?
Matt
10 February 2015 at 1:30 am #124510The measurements match what is called in the US a #9 machine screw as far as I can tell. I measured it for metric with my calipers too in case it was a metric machine bolt size, but it appears to be ANSI/ASME or whatever the US standard is.
10 February 2015 at 11:38 am #124529Yes it’s a silly question now I look back on it. The numbers in metric numbering refer I think to the diameter of the shank in millimetres (I forget what the technical definition is), but more than that I know how big M8 is and it’s probably twice the size of the little screw we’re talking about.
Looks like I’m going to have to rummage through my grandad’s motley collection of obsolete bolts from his time as an engineer. Unless of course the UK planes were made with metric threads, wouldn’t that be great.
Thanks again,
Matt
Not specific to this plane, but attached is some info on why just one missing screw is a problem when acquiring Stanley planes.

15 January 2018 at 6:31 pm #439474I know this is an old thread, but I have the exact same problem locating the same screw on my Stanley 45 type 12.
Here are my findings.
I found that the adjusting screw from my Stanley 54 spokeshave fits perfectly. So I can borrow that screw for now.
I also found that the thread/diameter is identical to the short screws on the tongue/sash matching cutters on this plane. It is also identical to the short screw that secures a small plate which in turn secures the cutter locking wing-nut on the main body. Unfortunately both of those screws are too short to be used on the fence.
Based on my observations I wonder if this screw is in fact a 10-28. Stanley may have used odd thread sizes, but they were very self-consistent. Even this odd screw/thread seems to have been used in many different parts.
Another workaround for those of you that have this missing locking screw: tighten the adjustable fence so that it is fully retracted. Use the plane in this manner, as if it is a pre-type 12 model. This way you lose the benefit of the adjust able fence but you have a solid locked fence to work with while you locate a suitable screw replacement.

15 January 2018 at 6:55 pm #439502Good information! Thanks. I never figured out the thread type conclusively. Whatever it is, it is not standard.

I did try matching it up to every screw I had in my toolbox. As you said it is definitely not a modern UNC/UNF. It is definitely not compatible with UNC 32 (e.g. #8-32), although it’s close. I don’t have a thread gauge so I can’t say conclusively. That’s why I suspect it could be a #10-28, which does not match any modern standard but was used frequently on vintage Stanley tools according to my research.
Scouring pictures and eBay, it seems that Stanley used two types of screws at this location depending on the production year. Sometimes they are cylindrical thumbscrew with knurling, and other times it is “spade head” (flatted oval) style.
I just bought some #10-28 screws, will report back once I get to try them.
Hi Derek.
I can sympathise. I have two 45s. One is quite complete and in fairly good condition. The other is not, its a donor plane.
Ive never noticed the threading that you’re looking for the bolt for, but it is there. It’s also not specifically noted in the booklet that came with the plane, it’s shown on the drawings but not mentioned in the list of parts. So I doubt that you could find a donor plane that had that bolt attached that isnt complete itself.
Alternatively, if you know what thread and size the bolt is, you could buy an appropriate old tap and die set and make your own bolt. Under the right circumstances you could probably get something like that really cheaply. Also, this is probably something that vintage car clubs deal with too?
Good luck. -
