Chrome 6mm to 24mm ($64) and 1/4" to 1" ($52). Impact 6mm to 24mm ($80) and 1/4 to 1" ($64).That’s a big set. Wonder what sizes will be available.


My Ernst Socket Boss rails will hate me for getting a 8mm to 22mm, leaving out 4 sockets.You can get the 3/8 impact metric semi deep from Capri minus the Ernst rail now if you're in a hurry.
The 1/4 drive semi deeps if offered in impact would be interesting to me.![]()
But Capri offers 6, 7. 23, & 24 mm as open stock in 3/8 drive impact semi deep just not in a set at the moment. Since red is for SAE and not metric, I prefer VIM Magrails, and the Capri semi deeps have been around for a while, I ran with those. Nice to see Tekton continues to release new product thoughMy Ernst Socket Boss rails will hate me for getting a 8mm to 22mm, leaving out 4 sockets.![]()

If you work on cars a lot you will use them everyday. They really help with clearance issues.What's the theory behind semi-deep sockets? Is it really worth it to add a 3rd set of sockets between my existing shallows and deeps, or is this a 1 size fits all solution if you're buying your first sockets?
That’s the direction I’m heading to as well. Just grab semi-deep for the SAE at the house and metric for work since I rarely use either in each situation.Hmm… an SAE 6-pt set in semi-deep is intriguing as a single rail solution for the things I actually use SAE for.
Exactly.That’s the direction I’m heading to as well. Just grab semi-deep for the SAE at the house and metric for work since I rarely use either in each situation.
Just wait until you see the extra shallow sockets. You will be adding sets #3 and #4 after the release date. Then, more socket rails, then matching socket rails, then a larger tool box.....What's the theory behind semi-deep sockets?

My guess is you haven't done many timing chain jobs of FWD vehicles.The theory is: manufacturers needed a way to sell more sockets to people with complete collections.
If you need them, you need them, but my impression is people buy them because they’re the newest thing and then use them because they own them. Not necessarily because of some application where only a semideep socket would fit.
I’ve gotten by just fine with deeps/shallows, personally. Maybe that’ll change in the future but so far it seems like hype to me.
I used all three depths of 1/4 and 3/8 sockets yesterday pulling replacing the take manifold and valve covers on my pickup. There were scenarios where only that depth…or a wrench…would have worked. They are incredibly handy.The theory is: manufacturers needed a way to sell more sockets to people with complete collections.

That does nothing to address the added depth in a semi-deep.These mini extensions are the solution that doesn’t require buying an entire set of sockets. I had several and love being able to get just the right length for the situation.

Includes: 1/4, 3/8 and 1/2 inch drive mini extensions. Create mid-length sockets by combining a standard socket with these extensions. SHA99020.www.tekton.com
I just measured my GW short and mids... that 1" extension makes a short 3/16" longer then a mid. Sounds minimum but that small difference can get you in a bad spot with your electric ratchet stuck!

On a different topic I dont see a need for mid length 1/2 drive for automotive work or atleast i have never seen it. I do need to pick up some 3/8" mid length swivels from Astro though. Anyone here that has removed a chevy transmission from a late model truck will understand!
Thankfully no - I work heavy dieselMy guess is you haven't done many timing chain jobs of FWD vehicles.

I was thinking about that the other day in the context of stubby sockets like theseThat does nothing to address the added depth in a semi-deep.
I bought my first sets of semi-deeps a few months ago. I haven't used them yet.Thankfully no - I work heavy diesel
And like I said originally: if you need them, you need them. Buy them if your work would be improved with them. I’m just not convinced that everyone needs shallows, midlengths, & deeps in all the drive sizes, chrome & impact, like manufacturers would like us to believe.
Maybe I’m wrong—wouldn’t be the first time.
As an HD tech, are they necessary, certainly no. Do I love my mids and use them almost always over deep or shallow? Yes. Do I still occasionally need deeps and shallows, also yes.Thankfully no - I work heavy diesel

Interesting. No 120mm, 4.75" or 5" to compete with other mfgr. offerings.
I’d like to see the heights of shallow sockets compared somewhere in this thread. I measured Snap on stuff a long time ago for a Koken thread. My recollection is that Snap on, Williams, and now Icon shallows are on the shallow end.
It’s possible some of those who feel they don’t need semi deeps, own shallows that are on the taller end of the spectrum. I suspect it’s also true that when you have them you use them and when you don’t, you may not miss them. But data would be helpful.
Found it: I even updated my original post
Suggest reading the whole thread.
You can almost think of them as regular sockets and shallows and deeps are the specialty sockets. A lot of times that’s how it is for me.Semi-deeps have become my go-to socket since I discovered them. They fit just about anywhere and I don't have to switch sockets nearly as often as when I only had shallows and deeps.
