Features: *Made from strong metal hinges and bolts, better than most plastic fixtures. *Rubber Bungs - The rubber bungs slide into the holes perfectly and when you tighten the bolts they squash up in the holes to make a good tight fit. *Non-rust Washer - Supplied with 2 washers. Washers will not rust.When you tighten the bolts the washers crush down into the holes, you need to be careful not to tight the bolt so much it pushes through the washer. *Threaded Design - The rubber grommets have a threaded section so you can just push them into the holes in the top of the toilet pan and when you tighten the screw it expands and tightens itself into the hole, without the need of a bolt on the other end of the screw. *Great for broken or old toilet hinges. Fits for most standard toilet with top fix hinge.
