Need a 3/8" drive 1-1/2" 6 point shallow socket - Source?

[dr_clyde]

We're working on a job where we need to check the torque on a projection weld nut on a part. The torque value in question is fairly low, so I'd really like to use a 3/8" drive torque wrench instead of a 1/2". This is an ongoing part number where we will need to verify that the torque value falls within a spec, and we'll record the torque values for the customer.

I can obviously use a drive adapter, or even weld a bigger socket onto a smaller one or even make a custom socket. But I'd prefer to just buy a socket off the shelf. The less parts I have to keep track of the better. I already had to make a custom adapter to fit the weld nut, so I'd rather not add more parts to the equation.

Can anyone point me to a 3/8" drive 1-1/2" 6 point shallow socket? I don't care if it's chrome, impact or industrial finish. I don't care what brand.

If they aren't made, they aren't made. But so far my looking at the usual sources hasn't yielded one.

Any input would be great. Thanks.

We make one for a tool truck brand I can probably ship you for free, shoot me an address

I'd look first to Tekton. They seem to offer many absurd combinations of drive size v. faster size. Reputed to be good quality as well.
You might make some product planner's day.

Please follow up on this if and when you get something. I’m interested. No reason other than “because I like sockets.” Thanks!

I saw this thread last month and thought why would anyone need a 1 1/2” 3/8 drive shallow socket and this weekend I’d have killed for one. Assembling fitness equipment, tight access and kinda low torque at least to get it almost done and could torque down with a wrench

instead here I am with a 1 1/2” combination wrench doing it manually 1/8 turn at a time

@Astro_Pneumatic_Tools i don’t need one now I finished the install and not looking for anything for free but can you tell me which tool brand and model number in case I need one again I’ll buy one from there

What sort of clutch is it?

I'm guessing somewhere there's an SAE equivalent of this set...
says its low profile oil-filter sockets on the box...

 

[mikey03]

Those don’t look shallow to me

Might look at low profile adapters too just for the odd sizes beyond. My set is a cheap Amazon set but they're about half as thick as a normal spinner ring adapter and don't have the extra space between the socket and ratchet to disassemble easily. Maybe 3/16-1/4 thickness added depending on size but there's even smaller ones without the knurling that looks to be almost impossible to remove without a prybar and a vise.

Only issue is getting them off, a mini prybar might be necessary, but they might help a bit if you're in a pinch and have a smaller 3/8 ratchet handy or need to work a 2-3/8 bolt down in a pinch point and need to use something smaller like a 3/8 in 1/4 body with the stacked adapters to run it down then torque with the biggest thing that'll fit after.

Also SO 1-1/2 in 1/2 drive Chrome is only $80, probably closer to $90 now since that was at least half a decade ago, last I checked if you're wanting to go the cheap route and buy the $30 adapter set to have more leeway with the next odd encounter with a nut getting pinched a bit too much for your tool to do anything comfortably and want that nice and shiny chrome(mirrored finish off the truck for some reason).

They stop at 1" for 3/8 drive

This one posted above looks to fit the need. It’s metric, but a quick conversion shows it to be 1.496 inches. Only off by 4 thousandths of an inch, should be fine. Maybe that manufacturer makes these in standard sizes as well.

I doubt there are any oil filters that use a 1.5" hex, but I would bet that the tolerances selected by a brand called KZINO (for this month, at least) are not particularly stringent.

The “checking torque” part piqued my interest. How does that work again?

I assumed it's just a "hasn't loosened" check

We are spot welding projection weld nuts on a customer's part.

They have a torque spec the weld must meet without breaking in order for the parts to pass QC.

Problem is, the weld nuts are not hexagonal or any shape a common socket will fit. I laser cut an adapter that will slip over the weld nut's profile and allow us to use a standard digital torque wrench to measure the torque required to break the weld and to spot check at the specified intervals to make sure the welds are meeting spec.

Yes, 38MM does indeed equal 1.4961", no cigar by definition.
A socket or wrench needs to be a bit larger than the fastener size. 1 1/2" & 38mm are close enough that one will work for the other, given the clearance needed, manufacturing tolerances and especially in this size.
Anyone curious about metric v inch interchange ought to measure a few tools of the frequently interchangeable sizes. I did so a while back measuring a dozen or so 19mm & 3/4" wrenches and found 19mm wrenches that were milled larger than 3/4" wrenches. At more than three times this size tolerances are greater and precision less important. I'd bet the farm the 38mm oil filter socket will comfortably fit a 1 1/2" hex.

Same brand?

If I’m trying to swap I pick the bigger one so I’d use 1 1/2 on 38mm but the other way might not work

but is 38mm even a size? I thought you go 36mm then to 41mm and skip the ones between tbh

Snap-On sells a 1/2” drive 39mm impact, but only in 12pt.

As far as I know, it is only needed in 12pt (for 12pt axle nuts on Toyota).

Yea those are for axle nuts and they run 12 point so that’s why but I mean in general i thought metric sizes jumped from 30 to 32 to 36 to 41 to 46 to 50

I know that I have 6pt 38mm in my axle nut sockets. In 3/4” drive I have 6pt 38mm as well.

In 1/2”, I have 33mm, 34mm, and 35 mm in shallow and deep.
In 3/4” I have 42mm, 43mm, and 45mm.

 

[ecotec]

Here are some 1/2” and 3/4”

I have never seen a 31mm, 37mm, 39mm… 40, 44… but, I would not be surprised if they exist…
