PH #00 or JCIS #00 Scews

To begin this is mainly about the screws that need to removed in order to change out the camera but it does apply across the board.

In iFixIt guides they call for the 00 Philips screw driver but in Apple's own self service guides and tool purchases/rentals it says JCIS bit. I know the differences between PH and JCIS is very minimal but it still seems somewhat important to know the difference.

So basically, regardless of how much it may or may not matter, which is the actual 100% correct tool? Does apple use JCIS screws instead of Philips or???

Thank you.

Hey there — I'm working on some iPad guides right now that call for a JCIS bit so I thought I'd weigh in.

The "100% correct tool" would be Apple's JCIS driver. This is because of slight variations in drivers across manufacturers. This bit (just the bit) costs $8 from Apple.

But do you need the absolute 100% right bit here? Nope. JCIS stands for Japanese Camera Industrial Standard and is just one size, to the best of my knowledge. It's very, very close to iFixit's JIS 00. We've not yet found a case where we can't use an iFixit JIS 00 in place of a JCIS. This costs $3 from our store. (Add a driver for $5.)

On top of that, we make our smallest Phillips bits to be compatible with JIS screws. So, an iFixit PH 00 will also work.

I'm emphasizing our tools because bits and drivers (and screws) can vary across manufacturers. I can only speak for iFixit tools. We use our tools when we make our guides, so we know they work.

Other JIS or Phillips bits might work, or they might not. You might be able to use a size smaller or a size larger if you're using non-iFixit tools. If you have your own, definitely try them (carefully) before ordering new stuff.

Happy fixing!

@splopenn maybe a short explanation why some OEMs use J(C)IS vs PH (torque etc. Excellent answer since this "before ordering new stuff" means saving $$$$ ;-)

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

I'm not entirely sure on that and would appreciate any insight! It seems like some people believe Phillips bits are *designed* to "cam out" if too much torque is applied, but others think the tendency to cam out is an unintended side effect of the manufacturing process.

Either way, it does seem that JIS bits in JIS screws are less likely to cam out than PH bits in PH screws. According to community reports and some testing, using a (non-iFixit) PH driver in a JIS screw is difficult or impossible, resulting in stripped screws, but a JIS driver in a PH screw is usually fine.

Manufacturer's reasons for JIS vs. PH could vary, I'm sure, and the choice could possibly be impacted by whether or not the manufacturer wants to control torque application, or it could just be because they want to use the most standard and widely-available parts in their region — or some other reason!

(And yes, it's always best to use what you have when you can — save money *and* reduce the amount of new production!)

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@splopenn the blunt end of the JIS and lower degree of the shoulder creates a shallower taper at the tip of the screwdriver. It leaves more "meat" to exert more torque. Of course, that will only apply with JIS screws :-)

That is why it sometimes works better to file (grind) down the sharp tip of a Philips screwdriver, since that will alter the angle as well.

Hi

This is a hard one,while apple says it is a jcis screw a Philips driver will work along side a jcis driver

So really it’s 6 and two 3s(the same thing with a slight difference)

Let’s just say for now that they are both correct as they both do the job and tick the boxes

Just as a example:A LCD tv makes a picture and so does a LED tv ,they are the same but ever so slightly different but roughly use the same process of getting what they are intended for

Hopefully this helps

Any questions please ask

Thanks:-)
