BEFORE YOU ORDER, Make sure that you are looking for the MTTB15W toilet seat mounting bolt. Please be aware this is not compatible with other toilets.
COMPACT DESIGN makes it easy to install. Good toughness makes it not easy to break.
The round hinge plate make this extra sturdy and ideal if your current seat fittings are loose making your toilet seat move around on the pan.
The rubber bungs slide into the holes perfect and when you tighten the bolts they squash up in the holes making a good tight fit.
Plastic washers will not rust like metal.
