6 point sockets: Impact vs chrome

[Dave.R]

Looks like the post got removed.

Some manufacturers use CR-V for all sockets, Some used CR-V for Chromes and CR-MO's for impact. It depends on the grade they are looking, CR-V isn't far behind CR-MO in strength, but its long term wear is better.

Sorry to answer the question, lesson learned. I'm not partaking in a mudfight just because it hasn't broke on you. Anyone have any questions PM me.

its not a mudfight. you made a statement of fact. you are unable to substantiate it. you continue to either avoid or be unable to provide any sort of an actual testing protocol that you undertook to reach that conclusion / 'fact'.

it is absolutely possible that impact sockets will yield before chrome when force is applied in a linearly increasing fashion. since you are unable to construct even that as a hypothesis, it follows that you lack the reasoning to test such a theory. the explanations you have provided as your 'process' hardly qualify as something that you could / should then extrapolate out to 'impact sockets' as a whole...or at all, really.

did you test one brand? 3? 5? did you do a materials analysis to see if those tested were all of the same type of metallurgy? did you test one size of socket? 3? 5? how many sizes would be statistically significant? did you test one drive size? which? why or why not different drive sizes?

you tried to speak authoritatively on a subject. as is expected, your methods were questioned. that is not a 'mudfight'. when they don't meet scrutiny well, the conclusions are questioned / dismissed. if the test method is invalid, the conclusion is invalid (by that method).

ahm

Princess Auto, here in Canada sells normal chrome vandanium sockets painted black as "impact sockets" and people buy them by the boat load when they are on sale. The only differenece is at the factory in Taiwan some were chromed and others painted black.

Late reply to the thread, but read it the other day and wanted to check before posting....i know it says what material they're made with on the link you posted, i went ahead and checked with my old man's "impact set" from PA and sure enough, you're correct....they're normal chrome vandium painted black. They recently had they're deep sets on sale for $7.99...i'll have to grab a set to fill some of my hansens.

There should be a hardness difference, even though they are both CR-V. Seems like a legal headache to let people use a standard on an impact, so I would bet the black oxides are more then just a different color.

I wonder if there are any requirements for specific metallurgy in order to label a tool with a particular metal type? I know there's got to be some ANSI and ISO standards for impacts vs hand sockets, and CSA is picky enough that I can't imagine companies get free reign to paint hand sockets and label them for impact when there are known hazards of using hand sockets on an impact.

This conversation has me all worried now. I'm going to try to get a extra deep impact socket on a nut to get to 185ftlbs with a breaker bar. Guess I ought to find out huh?

If you're talking about a standard/deep impact socket in 1/2" drive from a reputable manufacturer, most 1/2" impact sockets can take a 1100 ft./lb impact wrench (which is another topic) hammering on them and be just fine. You should be WELL within its limits, but still be careful. Knuckles tend to be highly allergic to hard objects, such as concrete floors.

you will be fine, as long as its a decent quality socket, and you can keep it on straight, as it sounds like you are reaching with that socket.

 

[GirlnAgarage]

The socket is a GP (2040XD) 1-1/4" extra deep. It was the only one of any brand that I could find a spec on having a deep enough bolt clearance.

 

[transittech]

You'll be fine, just make sure its straight (so it doesn't slip), like twoinch said.

At 185ft./lbs you're only about 16% of what a heavy duty diesel mechanic would likely push that socket too, and its got an engineered safety margin even beyond what we put them through. If they didn't, GP wouldn't be in business very long.

GP is good stuff, you'll be fine, that's not much torque for a socket that size.

Use of chrome sockets including attachments does damage to the impact and ruins the anvil.Chrome sockets and attachments are harder than impact sockets and impact grade attachments which can shatter.

i think that myth has been busted long ago. guys have used hard, cr-v sockets for many years and not damaged the internals of the impact wrenches.

girlngarage, you will be totally fine with your socket. dont let this thread freak ya out. like said above, that socket can handle a couple times more than what you are doing with it. you wouldnt believe the torque the diesel guys apply to sockets that size on a daily basis.

 

[Dave.R]

The chrome socket would blow before the internals would be damaged. On a good brand at a least. The hammers of a gun aren't a softer metal

Thanks fellers.
