4 Piece Toilet Seat Hinges Fixing Screws for Toilet Seat Lid Set, 4 Replacement Parts for Toilet Lid

The toilet seat fasteners are made of rubber, the screws are made of 304 stainless steel, much better than plastic fittings. The package includes 4 x rubber corks, 4 x metal washers, 4 x plastic washers, 4 x screws. The rubber grommets of the kit have a threaded section so you can simply push them into the holes on the top of the toilet bowl and when you tighten the screw, it expands and tightens into the hole, without the need for a bolt on the other end of the screw. Rubber stoppers slide perfectly through the holes and when you tighten the bolts, they tighten into the holes for a good fit. Please do not tighten the bolt too much. Plastic washers will not rust, better than metal washers. When tightening the bolts, the washers crash into the holes, you should be careful not to tighten the bolt as much as it pushes through the washer. The screw has a solid brass thread inside can be non-slip and rustproof. Rubber sleeve: 40 mm/1.57 inches, metal screws: 50 mm/1.96 inches, suitable for most standard size toilet seats in the UK with top hinge. Suitable for 14-16mm hole
