Well they're unmarked so grade 5 or less and there's a chart...

Don't think the coarse thread will take much more than that either, I'd be setting it at like 1/3 pound for everything. However, remember that most designs of breakaway torque wrench are highly inaccurate at the bottom 20% of scale so if it's in that end of the settings don't trust it much.

Thanks anyway, I found the electric drivers made by HIOS but I'm having devil of time finding 4mm HIOS drive with security torx T8 bit. Sony uses security Torx on every of T8 screws in PS4 and PS5 consoles. Microsoft consoles doesn't use any security screws at all.

HIOS 4mm drive bits are easily sourced but not all have the security feature.

Might have to drill tiny hole in every non-security 4mm HIOS torx bits. Doable but annoying and I don't have lathe or precision drill press.

The cheapest one I can find is 120 total shipping included for HIOS 4mm drive to female 1/4 inch hex adapter.

If I find another used HIOS CL-4000 electric screw driver with 1/4" hex, I'll buy one instead but not economical yet.

Cheers,

If a Canada Computers is not too far out of your way to wander into, you might find some low end stuff in there to put you on. I'd think places like Grainger, Newark etc would be the ones for the better stuff.

On average, I see 1 to 2 PS5 consoles a week for any reason. Rarely see 3 a week.

I do have local Canada Computers but this sells strictly computer parts, computers and consumer stuff, not the commercial tools.

I'm familiar with Ackland Grainger because back in the day, I went there for special tools occasionally. Their focus is on commercial daily stuff but does not have these tools for the production line tools.

The production tools is so narrow focus on tools for securing parts together efficiently in least time and less manual involvements with loose fasteners. Just plant the suspended power tool in the device for pick'n pull a screw, in one motion "thwack" on the parts and grind the screw in.

I needed the durability of the power driver. The ones like from Dewalt power screwdriver is not made for the heavy grind in and out daily and had already issues before. The carpenter's power tools for wood and drywall is too powerful and high rpm, very high torque and is not suitable for this. The consumer electronics stuff only can take low rpm and precision low torque to loosen and tighten them without damage.

How PS5 is put together is odd.
The PS5 metal plates halves are pressed shapes that have heatsinks on both sides that sandwiches the motherboard, in which held together with metal screws that is about 45 in total after removing the plastic shells.
Earlier PS5 had a aluminum plate that completely covers one ribbon connector release that is connected to the front panel with USB ports and buttons. If that ribbon cable is not released, cannot lift the motherboard out. Later version of PS5 had small steel plate covering this ribbon cable. This was put in use after 2 years of PS5 production along with smaller motherboard.

This also hides two final screws for the APU clamp.
Hence need to remove all 45 screws to let me to release this. These screws takes torque to undo and do them even loosened.
This has two requirements: Clean heatsinks and re-spread the liquid metal on both heatsink and APU's silicon die, that got dry spot after time and sometimes have to replace soldered in HDMI port connector.

The liqid metal's dry layer between heatsink and APU die happens after about 1 year of use or less.

Attention to anyone who wants to disassemble PS5 console:
Ribbon cables release for optical drive, (important! Pay attention how to release this).

Imagine taking out 45 metal screws:
The screws needed removed, and upper metal plate to access the PS5 motherboard.

Torque is measured in “ugga duggas” it is a very precise measurement that takes years of arm tuning and finger trigger feathering to master.

You can tell if you got it correct by checking that you lie somewhere in the middle of this precision guide:

Bolt is not in hole, can’t find it, where did it go?
Bolt is loose and falling out
Bolt exists and is in hole
Bolt is in more than one piece now
Bolt is now on other side of the hole…. How?!?

Anyway, the screws you have require about 0.05 ugga duggas

Hope this helps.

Hehehe.

Very funny. I have finely tuned mine "tighty, and can feel the stretching, just right" thing over the decades of turning screws. You have to caress the lady's when tightening screws into aged vintage plastic. 😀

Even the original PS4 (fat) has bad plastic now starting to break where plastic pillars are for the screws so I had to be very light on tightening torque.
