Master list of socket sizes

[LawnBoy-5247]

I am looking for a master list of socket sizes so I can figure out what I need to complete my sets. I don't need the really unusual sizes but would like a list with all the SAE and metric sizes for 1/4, 3/8 and, 1/2 drive.

 

[LB-1911]

This should get you started -

[larry_g]

As LB posted, grab any major tool catalog and look at their list for sale.

no neat sig line

 

[LawnBoy-5247]

Thanks for that list, here is an excel spreadsheet I made from it. You guys can feel free to use it and let me know of anything I missed.

let me know of anything I missed.

1. Missed 1/4" (between 7/32 and 9/32) in each 1/4" drive category.
2. Missed universal/swivel sockets, mid-length, and all varieties of impact sockets.
3. Missed male square drive (pipe-plug) sockets.
4. Missed Hex-key (Allen) sockets, and fifteen varieties of Torx sockets, including female Torx
5. Do you care about specialty sockets such as spline, spark-plug, thermal vacuum switch, O2 sensor, "Weatherhead", triple-square, Whitworth, and flare-nut?
6. In the 1/2" drive SAE section "I" would have no use at all for any of the x/32 sockets. In fact, I don't think I've ever seen one of those sizes.

Oh? Not just a normal part of the complete set?

 

[Schurkey]

Not at my house. What application do you find that has that size fastener head?

 

[pstemari]

9/32" fits a #10 lag screw. 11/32" fits a #8 nut. Machinery's gives wrench clearances for some of the bigger 32nds sizes, but I couldn't find any examples of fasteners that used them.

Could be that they used to exist on older machinery.

Every once in a while I'll run into some weird fastener that takes an 11/32nds or 17/32nds or 21/32nds. It's maddening.

 

[gungatim]

11/32 is extremely common, which is why it is always included in nutdriver sets and 1/4" drive sets. used all the time on self tapping machine/sheet metal screws, electronics, etc.

the other two not so much. there is also 19/32, again not so common. when I run into those sizes, they are generally the cheap Taiwan 40pc. socket sets, or old cman/snapon/S-K, etc. from 50's or earlier. I have never personally used them, and when I come across them (seems like a lot of double bone cman wrenches in those 17 or 19/32 sizes pop up) I always exchange them for normal sizes (especially since you can't generally get them anymore).

The OP did not mention what his expected use would be.
Some of these */32 sizes appear consistently on older machinery and equipment.
Need to know his expectations before making a call on these.
Japanese motorcycles, not much.
Old farm equipment or machinery, better get them.

 

[Greg85mcss]

For practical needs a good guide would be to look at socket organizers like hansen trats. They have spaces for things most people don't use like 23mm but still a good start.

How about adding a column for the semi deep sockets?

Every once in a while I'll run into some weird fastener that takes an 11/32nds or 17/32nds or 21/32nds. It's maddening.

These were often used during the 2nd World War, since the enemy didn't have access to this size standard, and couldn't repair and put back into their service vehicles that were captured and damaged. I remember as a kid, seeing advertisements in the back of magazines, such as Popular Mechanics, military tool sets for sale, so people that bought surplus old military vehicles could work on them, without having to resort to an adjustable wrench.

 

[Cruzan80]

Just had a Delta DP that had 19/32 bolts holdinghe motor to the mount. Dated right around 1952.

 

[leg17]

31/32" is the old U.S.S. standard for 9/16" bolt/nut.
25/32" is the old U.S.S. standard for 7/16" bolt/nut.
19/32" is the old U.S.S. standard for 5/16" bolt/nut.
11/32" is the old standard for #8 hex screw. Common in electrical work.
Craftsman used to offer a 21/32" socket, but I don't remember what it was for.
I think it was a specific auto related size.

Wrench needs depend on application.

Your master list of socket sizes is the Snap-on catalog. If it's not in there, it doesn't exist.

 

[Adam.C]

Your master list of socket sizes is the Snap-on catalog. If it's not in there, it doesn't exist.

+1 this is actuallly more complicated as you have sizes that aren't part of any std and are not particularly helpful, and you have sizes in drives where they probably don't belong. Look in the Snap On catalog for small socket sets. Those will be the most useful. Snap On includes a 15mm in 1/4 drive but won't typically include anything over 19mm in 3/8". This is because large fasteners can require torques a given drive size may not be able to produce.

I'm not sure what the goal is. Is it a list of all possible socket sizes? What about cap head screws? If you are looking for missing sockets in your tool box, cast your eyes in the direction of the myriad of cap head screw types and sizes. I needed an 11mm Allen and a T60 for a recent brake job. I had neither.

No doubt Snap-on covers a lot of ground, but they dont make them all.
One example is a 5/8" one-quarter drive socket.
It is available as Bluepoint, but not Snap-on.

 

[Mr.Nutcase]

I used a 11/32 in GM, I think it was on starter

 

[southalabama]

Buy a Hansen socket tray and have fun filling it.

 

[ChevyEFI]

In 1/4 and 3/8, I have rarely wanted anything outside what SK puts in their 47 and 49 pc. sets. 1/2 is another story. Socket racks with never-used size pegs are silly.

 

[Richard Cranium]

thanks for posting the chart.

 

[leg17]

Saw your chart.
I don't know what the application would be for 1~3/16.
Never ran across it being used or spec'd.

 

[cliftonbros89]

Only */32's I've ever used has been 11/32". Worked on quite a few pieces of older farm equipment and never had a need for the others. I've found certain 32nd sizes to be somewhat common on older sets of offset double box end wrenches.

As far as 1 3/16" I know I've used once or twice. I can't remember what but it was farm related also.

Lots of hvy eqip and ag applications.

Also can be a substitute for 30 mm.

 

[LawnBoy-5247]

My intention was to create a complete chart of socket sizes only, not considering torx, allen etc. I have revised the chart with semi deep sockets and I am planning on creating a condensed version with what you find on socket trays, I will upload them when I can.

 

[sberry]

11/32 on old coils tooI. ts not something a guy needs every style they ever made. There is no need for the old larger "32's" and most sets don't have them.

 

[leg17]

Not for fasteners but sensors, regulators, etc.,???

 

[sberry]

Some of those sizes were pre WW2. They probably are not in most master lists today and in practice could be covered by a metric.

I ;mean the 1 3/16. You said you used it on AG stuff. What for?

Sorry, wasn't you but KnurledNut.

 

[nbpt100]

I have used it on Axle Nuts. I think a Chevy. As Knurled Nut said it is very close to the 30mm and can be substituted. The difference is less than .5%. In general I have found if the difference is less than 1% you can substitute the next closest Metric.
If the difference is positive use a 6 PT socket. If negative you may have to use a 12 Pt. socket. Above all else use common sense with with how much play you feel. If it goes on firmly or with very little play you are safe. With larger sizes. over 1" you have more leeway.

For some of those x/32 sizes that are uncommon to many folks.

5/32 ~ 4mm
7/32 ~ 5.5 mm

Cheers

[jfcasey]

I have used 1 3/16 on heavy equipment as well. Also use 1 7/16 a ton but usually on stuff that's probably meant to be 36mm.

1-7/16 is very common to me it's a 7/8 heavy hex structural bolt.

 

[stage20]

A lot of 32nd sizing now corresponds with metric sizing, close enough it can be used for metric anyway. Make sure you include 6pt and 12pt sockets in your list lol

 

[Reaperre]

Hey does anyone know the metric .5 sizes? Examples being 4.5, 5.5, 6.5 etc. looking for a full list or as close to full as possible.

 

[Dave455]

Hey does anyone know the metric .5 sizes? Examples being 4.5, 5.5, 6.5 etc. looking for a full list or as close to full as possible.

5.5 is common - it’s the standard nut size for an M3 thread. 4.5 much less so (DIN standard 2.3mm thread) but those are the only ones I’ve encountered.
