Works for what it's meant to do
This is really the only way you can install a toilet seat in an installed Toto Carlyle toilet without reoving the toilet. Yes, crazy design but you won't experience that issue until about 25 years after the toilet installation and who stays on one place that long? Well, some people do and some people buy places that installed a Toto that long ago. The "fix" works and I don't understand the complaints other than you really have to work hard to push the bolt receptor into the hole (it isn't easy). Once you do, the rest is a snap and I have not had the toilet seat wobble at all.

A bit pricy but works great
We have a garden variety TOTO toilet (not the skirted version) and the seat has been moving side to side ever since we had it installed. The seat broke and had to be replaced and instead of using the bolts that come with the new seat I ordered these and I am very glad I bought them. They were pretty easy to install (a bit hard to get the rubber bushing into the holes for these old hands, but I managed) and the seat no longer shifts when it moves, I think they are a bit pricy, but they work - it would certainly be great if they shipped these with the toilet seats instead of the nylon ones.

New seat posts are great.
Great item, so happy to get new ones instead of reusing the old set.

Hot Seat
No experience with this type of toilet seat fastener prior to this purchase and they were pretty straightforward. Just barely managed to get this style toilet/toilet seat to work with a Tushy bidet.

Expensive but Work Great
When you replace a seat on Toto toilets you need these replacement bolts. Unlike many American makes where the bolts are reusable, the Toto's, unless you get very lucky, are not...you put them in once and if you have to undo them, you have to replace them. It's too bad and at $5 bucks a bolt $10 for the pair, this is sort of ridiculous...but if you have a Toto toilet, it's what you have to do. Once you get over the cost, you'll find these replacements work extremely well and once tightened you won't have to worry about that new seat moving about at all. They are expensive bolts and not easy to install...though easier to put in than take out...still, these are quality items that work well...and if you need them...grit your teeth and put your money down. They ship quickly and work very well and that will take some of the sting out of the purchase.

Work around for dumb Toto design
When I needed to replace the toilet seat for skirted Toto toilet I realized that there is no way to do it without pulling out the whole toilet …so dumb. Found these and they 100% work -problem solved! Also didn’t buy an over priced Toto seat -got one at Costco for $30.

Exact fit but avoid using a power screwdriver
I’m pretty sure I destroyed the original anchors by using a high-speed bit driver to unscrew them. This is why I had to order these. To be on the safe side, I used a regular screwdriver and slowly tighten EACH anchor 3-4 turns at a time - until they were tight (but not crazy tight). Tip: I used a large needle nose pliers to grab onto the top of the old anchors, then did a counter-clockwise pull upwards to get them out.

Works great...but...
This is an awesome little gadget that saved me tons of headache and money when trying to replace the toilet seat on a skirted Toto toilet. It works like a charm and deserves a 5 stars for this part. The only reason I gave a 3 stars was because I agree with other comments that we shouldn’t have to buy an extra part to get the job done just because Toto toilet seat turned disgustingly yellow over time and have no choice but to replace it. If this is how Toto decides to nickel and dime customers, they are making a huge mistake. No more Toto toilet for me-:(

We purchased Water Ridge one-piece toilets from Costco. They are a good product at a great price but the seats on 2 of the 3 were driving me crazy. Constantly lose and off center, we were constantly tightening the bolts. Very annoying. This product--what genius! They only took about 5 minutes to install and we haven't had to make any adjustments since then! Snug and tight, like a toilet seat should be! I don't generally get excited about plumbing hardware but this item is just such a stroke of genius! (Yes genius! And I'll say it again!)

The item arrived promptly and well packed. I bought them on spec for a Pfister Kamato toilet .... and they fit! I'm sure they would be great for the Toto toilets they were designed for, too! The rubber piece is 63 mm. long; the top cylindrical part of the plug is 10 mm. long and 17 mm. in diameter. Each un-expanded ball is 18 mm. in diameter and 13 mm. long. There is 23 mm. between the ball centres. The stainless screw is 66 mm. long. Recommended.
