KOHLER GENUINE PART 84999 TOILET SEAT ANCHOR KIT

Ridiculously expensive for what this is but it made the installing a 4 minute job! The Rivet studs should really cost only a buck or two, but ....I needed to drill out the old screws as they were completely seized which took a very long time though.I spent hours figuring out an alternative to buying this package and spent $20 but had no luck.So bottom line is that if you have a Kohler toilet with a blind hole, breath deep and spend the money.

I have (2) Kohler San Raphael low-rise one-piece toilets. I saw that since I purchased them about 18 years ago, that Kohler now offers a Quiet-Close with Grip-Tight Bumpers Quick-Release Seat.So, I ordered (2) replacement upgrade seats. Thought this would be a quick-easy swap (I should know by now that NOTHING is easy!). When I went to remove my first (old) seat, "one" of the seat anchors broke due to rust when I tried to withdraw the screw. When I went to the other toilet, same thing happened - "one" of the anchors stripped out. Before I knew this Kohler Kit existed, I had to find a way to get the old anchor screws out of the damaged anchors (as they would just spin). I already had a tool similar to the withdrawal tool included in this kit and that did not help. Since my old seats were headed for the trash anyway, I went ahead and cut the plastic hinges off the seat to remove the seat using my trusty Dremel tool with a cutting wheel. That gave me full access to the screw heads that were stuck in the anchors. I then used the Dremel cutting wheel to cut the heads off the screws. The broken anchors just dropped down into the toilet - first problem solved - old broken anchors removed.Now I was left with two empty holes in the toilet with missing anchors. That is when I started searching for this kit. It arrived today and made quick work out of replacing both missing anchors. Everything worked perfectly by following the directions. One thing I would caution is not to over-tighten the anchors when installing. What I used was a Snap-On Shorty Ratchet with a 7/16" extension to seat the anchors. I kept my hand right on top of the ratchet head (as opposed to the handle) so that I could get a good "feel" for how much I was tightening it - they don't have to be "that" tight - just enough to where the ratchet stops without really cranking it down. I then put a heavy coat of Anti-Seize on the screws before final installation just in case I ever have to remove them again.I doubt the removal tool would be of much use, but worth a try. The removal tool is apparently designed to help you hold and anchor collar from spinning inside the porcelain while you attempt to remove the retaining screw, but that is assuming that the anchor lost it's grip on the toilet and the screw is not rusted or frozen into the threaded end of the anchor (which both of mine were). If the screw takes a lot of torque to remove, chances are it is either corroded or suffered stripped anchor threads during initial installation. If that is the case (as it was with mine), then as soon as you apply the added pressure needed to break the screw loose, instead of the anchor spinning, it actually breaks the anchor in half! So in my case the anchor flanges stayed solidly anchored to the toilet, but the screw would just effortlessly spin inside the anchor since the threaded tip of the anchor broke off and stayed welded to the end of the screw after trying to un-freeze the screw. Hence the need for a Dremel.The installation tool and anchors saved me about $1,600 by not having to replace my toilets! My only complaint is that the kit (including the anchors) is at least three times the price of what the components are worth and should include a 3rd spare anchor just in case (IMO).

We have a Kohler Rialto.This fastening kit is just what you need to replace broken or rotted fasteners on your Rialto.When I originally installed the toilet I thought it would be a better idea to use stainless steel screws (phillips, no rot). While the screws didn't rot, a hack saw will not phase them. Which was a blessing in disguise to me.I got out my trusty dremel and a cutting wheel for it and cut off the head of the screw at 4 places. I cut these parts off at about a 30 degree slant so that I didn't have to ruin the hinge plate by accidentally cutting it.I only had to remove one screw and anchor because the wings on the other had broken and that anchor came out with the hinge.Kohler instructions suggest one can pull the screw and anchor out if necessary but I didn't want to risk cracking the porcelain. However, the toilet porcelain itself seems very tough.When tightening the new anchors I checked frequently by loosening the bolt back out to make sure the anchor was getting tight. It takes a few turns to tighten it properly but you'll know when the "wings" are up against the bottom of the holes because the anchor quits wiggling around.After installing the new anchors I used Duck brand reusable poster putty to seal the seams at the anchor to prevent you-know-what from going you-know-where. "Poster putty" has sat in my garage for years of temperature extremes without getting hard. So far I have found it the best solution for long term jobs like this. Just roll it out till it's real skinny and wrap that around the anchor then mash it into the voids.Once the anchors were prepped I replaced the seat and reinstalled the screws. The screws I wrapped with 1 layer of teflon tape to seal off the anchor threads so the screw won't be such a pain to remove if that ever is needed. I had used plumber's putty originally but over the years it hardened, hence the stuck screws.I also used some flat washers under the screws. The ID of the washer is a little larger than the screw but doesn't matter. Not sure why Kohler doesn't supply metal washers to go under the screws since the hinge is provided with a "rim" for the washer to set against to prevent excess movement.I plan on disassembling the seat attachments now after 2 or 3 years to make sure the screws aren't rotting since the new screws are carbon steel but the seat is nice and still, eliminating the necessity to swing those hips for better aim.The kit "wrench" to help for removing the old parts didn't work due to the screws having glued in due to the plumber's putty but it is pretty ingenious.It is def. worth the money to buy a dremel tool. Mine sometimes doesn't get used for years but when you need it nothing else will do.Sometimes I don't buy a part or tool out of principle because of the price but after years of scrounging stuff up I knew, like others here have mentioned, that using up time and gas to find parts was not worth it here.Just buy it!

Does the job perfectly for its purpose.I read many reviews saying this kit is outrageously expensive for what it does.When buying expensive cars, parts are expensive.Kohler toilets are not cheap (the model I have cost over $1,000), therefore it somewhat stands to reason that their parts are expensive.

Although I hate proprietary stuff, these work really well anchoring the toilet seat.
