Why do they still make 12-point sockets?

Like was said earlier, its more user friendly in tight spaces on angles. I put the passenger side doors on the M and R class Mercedes and using the 12 point is a must sometimes to double check the torque after I use the DC tool

Dodge ram front axles from late-80's/early 90's thru at least late 90's and maybe later have 12 pt hardware to hold the 4wd hub to the knuckle on the solid front axle. I've seen plenty more examples but too lazy to list em off.
Now, had you said something about those bastard 12-pt torx on volkswagens/audis, I'd definitely agree with you....

Aircraft hardware is very high quality. You usually break a wrench or a socket before you round off a bolt head. If the auto industry used better hardware, rounded bolt heads would not be an issue.

When you're dealing with heavies, you need to try to avoid having downtime due to a broken tool on the job. Like for example, a engine mount bolt on a A330 costs a grand each and you need 16 of them.
A turbofan blade on the 777 costs 36 grand each and there's a total of 22.
How about a engine pneumatic starter- $66,700.00 for each!
A main wheel brake assy. costs 60 grand for each wheel!
These are off the shelf prices.
Now compare a oil filter a $7 oil filter for cars isn't much, a oil filter for turbine aircraft costs $280 for the scavenge oil filter and $600 for the high pressure oil filter. Now you're gonna need two of each for 2 engines!
$880 just for changing the filters not including labor...

depends on the situation.. but 12 point sockets can be a life saver in a tight spot. i obviously use 6 points as much as possible though. newer cars are cake walks when dealing with grades of hardware. try an old car from the 70's with original hardware. 6 points usualy dont even stand a chance. i use a blue wrench
