Those screws aren't supposed to be reused. They're just there for assembly. When you change the rotor you're supposed to remove them and dispose as they don't do much to hold the rotor

I disagree with the last post. Although they are not crucial, they are supposed to there. They are often reused. The Home Depot ones should be fine or you can order new ones. Auto Zone or Advanced Auto may have them as well.

 

By "supposed to there" I assume you mean "supposed to be there". Who said they are "supposed to be there"?

They are used on the manufacturing line to hold the rotor "stable" to make it easier for assembly. The only purpose they serve after the vehicle leaves the factory is to make it harder to get the rotor off once they are rusted in place. D

Granted, I have a spare or 2 in my "brake box" and I've used them to hold the rotor "stable" when doing the brakes (sometimes) but I don't leave them in. I just did SWMBO's CR-V. I broke an impact tool bit trying to get one out. After that I resorted to the trusty drill. Those screw heads are so soft they drill right out in a matter of seconds.

 

They are absolutely not needed. They are for ease of assembly at the factory only. They can make it easier to install the caliper but you can use a lug nut or two. The wheel holds the rotors on nice and tight. If they didn't need to be drilled out upon removal then I put them back. If I don't have them I don't even give it a second thought.

If you are dead set on replacing them then make sure you get the OEM ones. I believe they're stainless. If you put something else in there and it rusts you will have one heck of a time getting them out. It's just not worth the trouble, either way. If there is one in there then it's way more than adequate.

 

One thing I've seen people do on these is to use an impact screw driver (idk if that's the actual name) which turns when you hit the top with a hammer

That's what DerbyDad03 and I were already discussing.

 

You don't need them. They put those screws at the time of assembly at the factory to hold things in place. You don't need them after that.

 

Thanks for the feedback, relieved to know they aren't needed at all...

I do not think they are stainless, as they are pretty soft, and do exhibit some surface corrosion whenever I've removed them. However, they live in an environment with severe temperature cycling, and "not all grades of stainless are created equal".

That said, 93600-06014-0H is the Honda part number. If you Google "Honda rotor screws", you'll find what you need on eBay or Amazon.

I use the above-mentioned impact screwdriver when the occasion arises to remove a rotor.

Yeah, you're right. Stainless is too hard. The last few I had wouldn't hardly stick to a magnet so I just figured stainless but didn't think that all the way through. Must be some kind of aluminum alloy or something then.

 

Another mystery! I mean, given just how hot things get there (and cold), plus contact with the elements, I'll admit they still corrode a whole lot less than all of the other components. Could be a lowest-grade-of-stainless, but still, it could be stainless nonetheless. Your batting average is a lot better than mine on these things, John.

There are many people that recommend using this screwdriver to remove the rotor screws:

Apparently the screws that Honda uses are NOT actually Phillips but, JIS (Japanese Industrial Standard). They are very similar, but the JIS has a flat tip that will not cam out. The bottom angle is 26.5° rather than 19°.

 

Hi I just replaced front brake pads and noticed the screws which should be holding the rotor in place as missing!!! with the wheel on the car, the rotor doesn't wiggle or move so I guess that's why it worked without any trouble... Anyway, I am looking to immediately put new screws in. From the description it looks like the m6 14mm flathead available from home Depot will be fine. What do you guys think? Or I could order OEM screws online and install when delivered... Honda Odyssey 2008 Touring

I have been driving Hondas since 1988 when I bought my Honda Prelude, passed by two Civics, one Accord and now this Odyssey. All of them came with those screws and they all disappeared when I changed the rotors for the first time at the Honda dealer on my Prelude. After spending a lot money with them changing the brakes, I got some real senses and started replacing them myself. I never installed those screws back, as they get stuck there very hard and are unnecessary for your safety drive. Install if you want, and don't if you don't want, it will not interfere with the handling of your vehicle.
