    Shimano Ice Tech Fixing Washer

    Just got my Ice Tech 6 bolt rotors for my new build. I went to mount them and when I looked thru the instructions for torque specs I noticed that they show a "fixing washer" that goes on before the tightening plates and bolts. Problem is that my rotors did not come with these fixing washers. They are brand new, in sealed boxes. Any thoughts? Do I need them? Has Shimano discontinued their use?

    My 203 icetech recently came in shimano packaging w/out fixing washer, too. A slightly different type of nut/retainer system, too - not the "bend-backs".

    Mine too. I read that a lot of people weren't liking the triangle headed bolts, so maybe they changed it up. I just put it together with what they sent me. Maybe it won't blow up.

    Yep. Same here. Noooo fixing washer. I'm going to guess that this would be the adapter if you were mounting to cl's. Hope so anyway. Wish me luck. These things are to expensive to mess up.

    I have a set of Ice Tech 6-bolt as well. I've ridden my bike with them for close to 300 miles without the fixing washer. Absolutely no problems with them at all.

    Ditto here. I'm installing a set today, and there are no fixing washers. Given that none of you guys has re-posted here that your brakes vibrated apart on a long downhill, I am guessing it is a re-design (or none of you survived the catastrophic brake malfunction).

    How about updating the directions, Shimano? Searching by part number on Shimano's web site does link to instructions that do not reference the washer, but still...

    Just received and installed a pair this weekend with no fixing washer. I'm guess the installation instructions are out of date. Game on!

    Shimano came up with that system because they knew that your average bike shop, much less consumer wouldn't take the time to safety wire their rotor bolts. It's good insurance to make sure your bolts stay put. Even if you have one come out, you've got 5 more. Some of the WW types run three bolts on purpose without issue in XC applications. If all of your bolts come out it's a sign from the cycling Buddha that you are not qualified to work on your own bike.

    New SM-RT86 rotors from Jensen. The 180mm came with silver fixing washer and tightening plates x 3, with the triangle head bolts mentioned above, exactly as shown in the tech docs. My 203mm however did not include a fixing washer, the tightening plates are black with a different style tab, and the bolts are have rounded heads, not the triangle type.

    Seems like the consensus is to just use the included hardware w/o the fixing washer for mounting.

    Nobody has had any issues when mounting without the washer?

    Trying to decide if I should try and get a washer or just go ahead and install?

    Thanks for the input!

    I bought both 180 and 203mm rotors from Jenson and neither came with the silver fixing washer. Both came with the rounded head bolts and 3 black tabbed plates. Just installed what I was provided and no issues. From what I have read, the fixing washer was the old style that has been discontinued. Would have been nice of Shimano to update their documentation so there isn't so much confusion.

    LOL, that comment brought a chuckle to my face. I think Shimano is being extra conservative liability wise with these retainer washers. Witness the little detent that you have to depress to open the clamp on the XT M785 brake levers. Absolutely no need for that except for the lawyers. If your brake levers come open while riding because you didn't tighten them properly it's definitely a sign from the cycling Buddha that you are not qualified to work on your own bike.

    Torque the rotor bolts to spec, with a bit of blue Loctite if you're really concerned and anal, and enjoy the ride. (I'm not concerned about them vibrating out, but I am anal like that so I did use the blue loctite on the threads, like I do when working on my car and securing critical fasteners.)

    Not anal enough to refer to the loctite product number though. Referring to a thread retaining compound solely by it's color is pointless.

    That's more like it. It's nowhere close to being 'standard' though. It is the common one found in many hardware stores though. Loctite does a few thousand products and a little less than 1/3 of them are blue.

    I just got my 203 rotor and is without washer. I'm only concern if the rotor won't deviate or brake on the black central part. Work fine so far on the road. I'll see on Enduro ride what'll happen

    They make 3 main thread-locking products, blue, red and green. Threadlockers from Loctite Products | Threadlocking / Mechanical Gasketing | Loctite Adhesives

    They then also make "special" versions of their "standard" threadlockers for high-temp applications and other special uses. Most people understand "blue loctite" to mean their "standard" or "general purpose" blue threadlocker product, and "red loctite" to mean their "standard" or "general purpose" red threadlocker product.

    I keep two different green colored loctite products around. One is 680 the other is 290. You wouldn't want to get them mixed up. The 680 is a bearing retaining compound and the 290 is a wicking medium strength thread retainer. I also carry 248 instead of 242. Chemically its the same thing, but 248 is in glue stick like packaging.

    Search 'blue' on the page you linked and you come up with 52 results. You absolutely need to refer to a number. I'm sure the guys at loctite don't think it's possible to sum their catalog of a few thousand sku's down to three colors.

    If you want to simplify your life by keeping 2 or 3 different products around and referring to them by color that's great. But some of us need more than 3 different compounds and realize there are thousands to choose from.

    No, I hear ya - I have a wide variety of "specialty" loctite products on the shelf in my garage, also, including bearing retention compounds, high-temp and oil-resistant threadlockers, etc.

    But generally speaking, when it comes to bolt threads - people know what "loctite blue" and "loctite red" refers to: the loctite general purpose thread locking compounds found at the local store. So much so, that permatex sells/markets its thread locking compounds as blue/red, also. Threadlockers.

    In the world of thread lockers, "standard blue" is very discriptive. People understand that the blue threadlocker is the "easy remova"l variety, and "standard" just means the general purpose type with no special properties.

    Just got mine and no fixing plate, either. I was also surprised in the instructions on the lack (maybe intentional) info on aligning the calipers and bedding the pads. It just says to loosen the caliper mounting bolts, squeeze the lever and tighten the bolts. Maybe I'm just used to the lengthy instructions for crap Avid hydro's. ;-)

    Building my Gunnar Ruffian and was stumped tonight with the lack of the plate for the rotors. Thanks everyone for the insight. I'll go with the blue locktite as well.

    Was the new style screws and attaching devices the only change in the updated rotors? Are these what they consider V2?
    I just got a 180 from Nashbar that was supposed to be V2 but it sounds like it has all the old hardware.
    I'm still waiting for my 160 too get here.

    Not sure about that. I got the 160 ice rotors from local bike shop. I followed rec in post to put locktite on screws and just ride. Like everyone...I was concerned when part was missing and instructions were apparently out of date.

    My screws already had blue loctite on them. Brand new out of Shimano packaging. No fixing washer for me either on both 160 & 180 ice rotors

    Shimano Ice Tech Fixing Washer

    Is that what those things were for I threw them in the bin not needed. As long as you know how to do a bolt up....

    Hi, i received one of my ice-tec rotors today and that also doesn't have the fixing washer. However mine has also come with only 2 tightening plates instead of 3. Will it be safe to use it with just 2 until a replacement is sent? As i'm really impatient and want to get testing my new brakes and rotors. It is the rotor for the rear brake so it won't be being put under a great deal of pressure.
    Thanks.

    I found the same thing a couple months ago when I bought a pair of 160's. I noticed on the back side of the bolt heads there are fine serrations that engage with the little tab on the tightening plates. I guess they just didn't bother to update the instructions.

    Did you mean the fixing washer, or a missing tightening plate, if it was the plate did the shop you bought it from replace the missing plate, or are you running it with only 2 plates. If so have you had any problems due to only using 2?

    The pair I bought were only missing the large fixing washer. Both rotors came with 3 tightening plates. Are you sure your missing one ? When I first took mine out of the little bag 2 were stuck together, was hard to tell at first because their so thin.

    If it were me, I'd torque the 2 bolts missing the plate and run it until I got the replacement. If you choose so, just don't hold me liable
    Really though, look at all the rotors out there that are attached with just the bolts and thread lock.

    I purchased Ice Tech rotors from two dealers on eBay. The 180mm came with the 3 black tightening plates & the 160mm came in a box with 3 tightening washers of a different style plus the larger silver washer. I saved about $7 per rotor plus postage (another $10 or so)..

    Am I understanding correctly that newer rotors are only using the black plates & that some of you are ditching all of it and just using the bolts?

    I haven't purchased the M785 brakes yet. Plan on doing that later in the month. I hope...

    I have just bought a SM-RT86 disc with missing fixing washer and out of date instructions. After being back to my shop and not having found a solution, thanks to this forum I didn't spent a lot more time looking for the fixing washer. And now I have just found that on the Shimano website Shimano if we search for the SM-RT86 product, we get the SM-RT81 instruction that concerns both system, central lock and 6 bolt type. And for 6 bolt type they says "Install the rotor and the rotor tightening plate to the hub, and then install and tighten the bolts" so no more mention to the fixing washer.

    After two calls to Shimano I can again confirm thet they no longer use the Fixing Washer. If your rotor came without them you won't need them. It should also be mentioned that they have redesigned the bolts and Tightning Plate, they are now reusable and unavailable from Shimano.

    Also FWIW, Cannondale says the Shimano bolts "failed their testing", they spec their own bolts and recommend tighting them to 7.5nm.

    Just got brand new 180mm / 160 rotors, no washer, old instructions. I guess they must have printed out a hell of a lot of them to still be using the old set.

    Not entirely sure how these new tabs are supposed to work though. The instructions made sense with the triangle headed bolts, but not so much on these round headed ones.

    Edit - Oh I see, they grab a ridged part in the bottom of the bolt. No need for folding etc.

    I got ti bolts to use for the rotors but decided I would use the steel ones that came with because they already had loctite applied. But The first bolt started to strip so I used the ti bolts and blue 242 loctite. Ti bolts had deeper t25 socket only time will tell if they hold up as well!

    Well, it's much later now. Still same instructions. Still no fixing washer. Plan to go ahead with kit as delivered and torque to specs. No plans for Ti bolts at this moment. But it will happen in time.

    I only got the chain bit looking washer bits n bolts and didn't get one of those rotor plates either=? Mr Shimano never shows it all does he, although yeah the company is trillions? That includes crap instructions for every Shimano product I've ever had aswell. Actually most are more annoying and confusing than actually just working it all out myself to put together. Maybe it's Shimano's selling point to help the bike shops? Eitherway maybe the newer ones just don't come with plates cos Shimano doesn't see the point in them now=?

    Glad I searched this issue. No "fixing" washer for me, either--almost didn't ride today.

    As for the "tightening" plates: Two of mine were stuck together such that I didn't notice at first. Luckily, the issue was discovered before tools went flying--especially because I'm working on the dining room table. lol.

    It's good to see that I wasn't the only one concerned about the "fixing washer"
