I make a living with my tools (from snappy to HF and all the in between ) and if a pro can't make a solid living in today's day with the brands you yourself listed then they are the problem not the TOOLS...
6 point sockets don't round bolts dumb mechanics with 12pt HF wrenches and sockets do,
but hey you cant fix stupid.... Right?
Ironically your the type who buys a $1 mag pickup tool to save $5 bucks vs buying the real ullman tool (same as craftsman, bluepoint....) one and then complains when it cost you 3 hrs...
Who's fault is that?
These sure do look like 6pt sockets:

Never said it wasn't my fault for buying the cheap tool. I am saying I learned my lesson to stay way the hell away from most HF tools. Hell i trashed 15 tools from HF right after and replaced them with good quality ones.
6pt sockets round bolts. Normally it is a fitment issue. Either someone uses the wrong size ie metric instead of standard or vice versa or the sockets themselves are not to close enough tolerances.
Then there is the fact that cheap metals will flex and deform allowing a socket to bend and round the corners on the bolt using the flats of the socket. This is why chrome from the same brand as an impact will round a fastener easier.
Bolts are not like what they used to be. They are made as cheap and light as possible. So they tend to round easier. Also on most cars anyway they do not use only grade 8/10.9/A2 fasteners they use all grades. Also the bolt heads will not always be on par for the size they are supposed to be. ie sometimes a 19mm fits tighter then a 3/4" socket on a 3/4" bolt.
Then there is corrosion a rusted fastener will not have the same size when part of it has rusted away. Though this is not in play with what happened to the tech i was talking about it still will happen.
It is laughable that you think a 6pt will never round a hex head. Must be an engineer.
Hers a better question, how much does your "2yr tech" make? Then explain to me how it makes sense he buy the most expensive tools available? If he can't use HF sockets, which MANY people in here do without issues, what leads you to believe the s/o sockets will solve his problem? You can't buy experience- no matter how much you spend.
He makes enough to buy lunch out every day at $10-15 a day. Makes enough to buy everyone rounds at the bar every friday. $50-60 bucks. So i would say he makes enough to invest in Expert or Blue Point sockets which will work just fine for a good long while. An expert impact 3/8 set was recently on sale for around $130 bucks. So ya tool truck brands so expensive...... Not to mention he wants to do this for the rest of his life and is adamant about that.
I dont disagree with much of what you said, but if a 'technician' is rounding off bolt after bolt, something is wrong and its not the bolts or the sockets (unless you consider using an SAE socket on a metric fastener the socket's fault). I will admit, Im not a professional but I do ALOT of DIY auto tech stuff for myself, friends, family, and neighbors and I have never rounded off a bolt that wasnt my fault (using the wrong socket or coming at a poor angle).
Ever pull an exhaust manifold, exhaust or intakes off? Heat cycling and rust make fasteners very very tight. (The manifold rusts to the bolt ie closing it in tighter around the threads) He was not using the inappropriate socket type it was metric for metric. There is just way too much play in the HF sockets. Also people install fasteners with impacts which makes them considerably tighter then they should be. Not all techs have a clue.
I have rounded plenty of fasteners that were not my fault. A lot of them were heat cycled, cheap bolts, rusted fasteners, crossthreaded bolts/nuts, partially rounded before i got there, someone used loctite red on something that doesn't even need threadlocker.
I have also rounded plenty that were my fault when i was rushing, not paying attention, doing stuff at a friends place who has "good" tools ie chinese craftsman or HF. So i didn't bring mine and show to find poorly made tools. I rarely use 12pts and only on occasion do i use sae on metric and vice versa and its normally when it fits better. Every once in a while that will bite me as well.
