Hibbent Universal Toilet Seat Screws and Bolts Metal - Hinges, Fixings Expanding Rubber, Replacement Parts Kit (5 Choices)

Great product. Easy to install with easy directions.

These bolts really are "heavy duty". I've had these installed now for about a year and they show no sign of leaking or corrosion.

Straight forward universal parts. Allowed me to complete electric bidet installation without incident. Needed parts ASAP & wasn't disappointed. Good quality & stable mount.

These unfortunately were not long enough for our installation because the toilet lid was self-closing. As a result, it was fastened to the seat and bidet as well. I had to order longer M8 stainless bolts. That is not a problem of the seller or the merchandise, simply insufficient installation instructions. If you are installing a bidet seat on a skirted toilet, you need these. Big box stores and local plumbing stores do not carry these. They say to use a special wrench in a space in which you cannot see, cannot support a nut, and cannot easily hold it to tighten. I wouldn't even want to think of needing to remove a regular bolt. Sounds like a reason to have to call a plumber every time you need to tighten a seat. But not with these ... they install as easily as similar smaller ones on my kayak ... where no wrench would ever reach. I bought an extra set of 6 just to have on hand.

Nicely manufactured, easy to fit and works well. Do look at the assembly diagram included.
