Snap On Cracked AGAIN!!!! PFFFTT!!

[scooby074]

Thin walls and rusty nuts. **** happens I guess. But thats what you pay for with SO's warranty. Driver will exchange that in a second.

I got a deadblow ballpien that just fell apart. Urethane rot got it. Should be no problem with the warranty, but I gotta find the driver since Im not on a regular route anymore. I dont blame SO for it.

Snap-On sockets are noticeably thinner walled than most other sockets in the majority of sizes. Check out the difference in wall thickness of a Snap-On 1/4 drive 10mm vs the Capri Tools equivalent, below. .024 larger diameter! Thinner walls mean a given torque creates higher stress in the socket. Beyond a certain stress level, you have a finite amount of life in the tool. I am willing to guess the socket did not break from seeing 120 in-lbs, it broke because it saw too many high stress cycles before that.

It was 2 weeks old. It never saw serious torque. These replacements last only a couple of years.
Four almost 4 decades, When my Snap On and Matco sockets come up at the end if life cycle they just develop a loose fit. I replace them at that point. Its a metallurgy thing. Takes just one dude with an alcohol or other problem and you have a bazillion pieces of junk out there.

Could be a defect, but how many times has that socket been pushed a little harder than it should have been? The lead on chamfers on that socket looks like they have been hammered onto fasteners. None of my chrome sockets look like that. The impacts are a different story.

Dunno, the walls on that socket don't look any thinner than any brand I have- SK USA, Williams USA, Craftsman USA, GW, HF......

But it looks beat to **** to me and looks like it's seen much abuse. Not like, "I just bought this yesterday and tightened a screw to 120 lbf-in on a torque wrench and it broke. But more like it's seen much impact use in the past and now it failed and SO *****.

I won't argue this, but that's my observation. And 1% of my tools are SO, and IIRC I literally have one SO socket that I inherited and have never used, so I rarely defend SO as being superior to the other brands that sell for a fraction of their price. Sorry, but from my eyes that's seen a lot of use or abuse.

That things looks like it's been hammered on quite a bit.

Socket shown in OP looks new, except for the crack. The sockets shown in post #2 are not OP’s.

one thing I do agree with from this thread is current production snapon hand tools not quite the extreme durability of older manufactured examples .
I not seen or personally had many tool failures (tool truck or mid tier offerings) in almost 5 decades of daily use .
I could count amount sockets I had split on one hand even if lost a finger or two (and I do use chromes on air/battery ratchets and impacts on occasions ....

Obviously a defective tool that the OP had. Not sure why anyone is busting his balls over it and claiming it was abused, end of life due to duty cycles, etc. No matter who made the tool, it can happen. That's what warranty is for. What is odd is that the OP has had it happen repetitively. Would make me wonder if the driver has a stock of replacement sockets and more than one failed one came from the same lot? What is the date code on the newly failed one? Is it an old date code?

I had that problem with Proto 1/4" drive. Not with any of the other drive sizes. They kept stretching and breaking. Replaced with Snap-on, and only one has ever split, and that oddly enough was 5/16" deep, same as the 8mm. It was warrantied out, and the replacement has been flawless. I also confess to using 1/4" drive to their limits; I use them in preference to 3/8" a lot of the time. The 5/16" was well worn when it split.

I have had Snap-on sockets split a few times; probably as much or more than other brands, but I use them more and harder than others, so not a fair assessment there. I know I've split two 1/2" deep 3/8" drive, a 9/16" deep, and a 5/8" deep in recent memory. The deep split more, probably because of side forces or tipped angle use in addition to torque. Those were after much repetitive use. I also had a brand new 16mm proto break, at low torque on the first use. the warranty one has lasted 15 years since. The good thing about Snap on breakage is it is convenient to replace them, and the replacement under warranty is unquestioned. But, as the detractors have noted, you pay for that convenience up front.

I'd like that project farm guy do a comparison between 1/4 impact vs chrome sockets. I have a feeling those impact sockets can be trusted a lot more than chromies.

8mm 6PT on Snap On torque wrench QD2R200 ( last calibrated 4/23)
Set to 120inch pounds torquing down turbo pedestal. Was using to teach student. After 39yrs., I frickin know what 10pounds feels like. Got to about seven and crack. Socket snapped. Kid looks at me and asks, “ How money was that Snap On stuff”?
Ive broken 5 of them in 6 yrs. Pitiful that you need your Craftsman to back you up!! Cant remember last time I broke one of them!

It would be interesting to see how long the Cman would serve if you were to put it into regular service. Now with the next SO replacement on deck. Might be an eye opener.

Wrong. It was going in. Threads were perfect. It cracked around 7 pounds.

OK - but what else has it worked on? You've been through too many of these things for 7 ft. lb to be what's actually breaking them.

I've always heard that part of the reason mechanics like Snap-On sockets is because they have thinner walls and can sometimes fit in spaces that other sockets won't fit.
