Tools (Sockets, Wrenches, Spanners) With Sizes in X/64 "?

[YoshiMoshi3]

Does anyone know manufacturers that made tool sets like sockets and wrenches that come with across the flat dimensions specified in X/64 "? For example 21/64 ". I would imagine only a limited amount of tool companies would have made tools in such sizes, and that the list would be rather small. Is there a list somewhere?

I know ignition wrenches in 13/64 " and 15/64 " are still a bit common and still made today. I think I have to get into older stuff to more odd ball sizes.

Please and thanks.

Are you goofing on us? Or do you have a really short memory?! We just went through this a few months ago at the tail end of your very similar thread inquiring about x/32nds sizes.

Here's your query in that thread...

I know this is a bit off topic, but are the 53/64 and 57/64 the only X/64 sockets known to exist? I know that there are some lug nut extractor sockets that are splined drive that are modern made. But I think 53/64 and 57/64 I think are the only vintage made sizes.

Here's my reply...

Mossberg made detachable heavy-duty sockets with an entire range of /64" service opening sizes - from 29/64" to 1-17/64" - in the late 1920's, after pressed steel, before hot-forged. I have a few. See the 29/64" below and a link to my GJ post with photos of other examples and a catalog cut here.

There's little doubt this practice emerged from their propensity for making a range of sockets with /64" service openings in the Brass Era press fit to fixed handle socket wrenches, such as these Tee Handles from my collection.

And another one...

Here is list of Williams socket wrenches made with /64ths sizes.

My bad. I couldn't remember if I created a thread on this or not, specific to this question. I'll take a look again at that. Thanks.

No worries. I should've put a smiley face in there somewhere.

So looking at the Williams stuff, it looks like they advertised openings in x/64 " increments on the tool catalogs, but the tools themselves were stamped with x/64 " - 1/64 " increments? Is this accurate?

So a 41/64 " advertised openings in the tool catalog would be stamped with 5/8 " on the physical tool itself. Where the extra 1/64 " in the opening is just for clearance.

Where the Mossberg stuff is different? The tools are stamped with x/64 " on them and are exactly x/64 " in opening with no extra clearance? I remember you had a picture with a measuring tape of one of your x/64 " mossberg sockets and it looked dead on with no extra clearance. Any chance you can please measure with a caliper to confirm the theory?
So a Mossberg 41/64 " stamped tool has an exact opening of 41/64 " and does not have any clearance, meaning the opening is not 83/128 " but is exactly 41/64 " and is effectively a 5/8 " wrench with 41/64 " stamped on it instead?

No worries. I should've put a smiley face in there somewhere.

^ Appears to be document spec only. I don't have and I have never seen any of those regular range /64ths wrenches in Williams. Only the Mossberg. And the occasional specials that everyone else has, typically spark plug wrenches.

Thanks for confirming. That was the conclusion I was coming to, documented spec only, and not stamped on the tool.

Any chance you could please measure one your x/64 " mossberg tools with a caliper please to see if there is any tolerance over the x/64 " value stamped on it? I'm suspecting that while it has x/64 " stamped on it, it is equivalent to the "normal" sizes that have a 1/64 " tolerance over the value stamped on the tool. Meaning a Mossberg 41/64 " socket is the same exact opening as a regular 5/8 " socket? Mossberg just decided to stamp 41/64 " on a 5/8 " socket?

If it dead on and exactly 41/64 " then I would think so. But if there is some tolerance and it was made to actually be 41/64 " with a small tolerance above that than it may actually be a true 41/64 " socket over simply a 5/8 " socket with 41/64 " stamped on it.

I'm also coming to the conclusion that Mossberg at one point restamped all of there x/64 " tools to the "normal" values like due to confusion. Is this accurate?
Sample A

Sample B

Both Sample A and Sample B have the same part number 363. But Sample A has 3/4 stamped on the handle while Sample B has 49/64 on it.

I think Sample A came out after sample B.
3/4 " + 1/64 " is 49/64 "
Kind of supports my theory?
The 49/64 " tool is exactly 49/64 " and is the same thing as 3/4 " tool with a 1/64 " tolerance with "49/64" stamped on it. Maybe later on they decided not to stamp it with 49/64 due to confusion and just stamped 3/4 " on it due to confusion. But it's the same exact toll with the same exact opening? They are both exactly 49/64 " in opening and identical tools. One has 3/4 stamped on the tool while the other has 49/64 stamped on it.

I don't have any of these x/64 stamped tools from Mossberg so I can't confirm my theory.
