Stanley 140 Cap Screw

[Dan T Jones]

Here is a picture of the cap screw from my newly acquired 140. As purchased it was frozen/rusted in place. After a week of penetrating fluid it came loose. Obviously it is bent. It has 24 tpi which from what I've read is the wrong size and certainly would also contribute to it being jammed. All that said, it does look "authentic" to me - not your normal screw from Lowes.

Just wanted to check with experts, especially someone that may have a 140. I did check with Bob K and he did not have the replacement screw. I failed to ask him about the thread count.

Thanks for the help.

You might try a 1/4-28 or m6.10. I can't speak because my 140 is a lie nielsen. The 1/4-28 and m6.10 are on other vintage Stanley block planes that I have.

All the spares I have are from Stanley 9-1/4 through 220s.....fixing to post all my spares on that auction site after a bit. Seems I need a bit of room in the shop, might as well sell them off....so I can buy more stuff.....

[Dan T Jones]

Steven, are you saying that you may have the 140 cap screw?

[steven c newman]

I have one from a Stanley #9-1/4 , and a couple from the #220 block planes. The 9-1/4 is quite a bit bigger than the 220 bolts, both in length and diameter. The 9-1/2's bolt also has a non-threaded area under the head, for about just under half it's length.

Not sure what postage would be to send your way....

[Dan T Jones]

Steven, I think my screw is about 3/4" long and is maybe #12. I'm thinking it is supposed to be 20 tpi. I will check on the length. Would you please check on the thread count on the screws you have?

You might take your plane to Lowes and try to match the threads there. They have an excellent collection of screws available. I have matched screws by doing that.

[steven c newman]

btween 10, and 13 in the 1/2" of threads on the bolts There is a 3/4" long one, that came with the lateral lever on a stanley 9-1/4. Might go and check a lateral lever bolt on one of those?

It may be a few hours before I can get to the shop, but I can check on my Stanley #140 if it will be of any help.

Jim,
That would be great Jim. I was hoping someone would have a 140. My screw (pictured) measures 3/16 diameter, 5/8 long, and 24 tpi.

[Jim Koepke]

The cap screw on my #140 measured to be a 10-24. The outside of the threads measured at 0.182".

The socket on your #140 may be coated with rust and grunge inside.

These folks carry the tap:

The problem is they have a $25 minimum order.

It should be available locally elsewhere if you do not want to purchase $25 of odd tooling.

They also carry some of the odd sizes of taps and dies used on Stanley planes. I recently purchased a 12-20 die and some other items from them.

Jim, thank you so much. The tpi is the same as my screw.

I said 3/16 which is .1875. I didn't use a micrometer. Maybe the screw is the correct one and I can straighten it. I have a 10-24 tap so I will try to clean up the threads.

I also have a no. 5 that needs the short horn screw which is 12-20 I believe. If I can't find the screw I'm thinking to try my 12-24 tap and get a new screw. If that doesn't work I'll step up a size and rethread.

Thanks again.

This has no bearing on the question, but as a matter of record, my Brass Lie Nielsen 140 is 10-32. I checked it with a thread gauge.

Dan, you are welcome.

The 12-20 on the tote toe screw for your #5 is the same as a frog screw. When I saw the cost of one I made one by filing a frog screw into a rounded top screw. Since then I may have come across a replacement to use. I think my old #5 still has the modified frog screw in the tote.

BTW, frog screws are less expensive and a lot easier to find than the tote toe screw. I have a few frog screws if you do not have any.

The only reason to use proprietary hardware is to have a corner on the market. Not really a good idea as Stanley has pretty much drifted out of the spare parts service.

That's true. The local Lowes has a pretty complete assortment of SAE as well as metric fasteners.

I recently bought the thread checkers being sold on a cable. I bought both SAE and metric.

I have looked at many a hardware and fastener supply store and have not found any of the thread size & pitches used commonly on a Stanley plane.

If you purchase a thread gauge make sure it has 22, 24 & 28 tpi blades. 24 is somewhat common 22 & 28 not so.

336809 These are the thread checkers I bought.
It has the common sizes you will find in the bolt bins at the store. You screw bolts into the gauge or nuts onto the gauge.

If I run into a blade gauge, I will get it.


When you start working on something like hand planes, and your wanting to buy nut or bolt to fit , they work pretty good. Having both metric as well as imperial, I know what to buy.

It does have a 1/4X28 gauge. Each gauge has male and female ends allowing you to check bolts as well as nuts.

[Jim Koepke]

Interesting, I'm not sure I have seen those.
