[UNIVERSAL FIT] Great for broken or old toilet seat hinges. Fits most standard toilet seats with top fix hinge. Suitable for 14 - 16mm holes. [RUBBER BUNGS] The rubber bungs slide into the holes perfectly and when you tighten the bolts they compress inside the holes to create a secure, tight fit. [THREADED DESIGN] The rubber grommets feature a threaded section that allows them to be pushed directly into the holes in the top of the toilet pan. Tightening the screw expands and secures the grommet in place, eliminating the need for a bolt on the opposite end. [PREMIUM MATERIAL] Made with black expandable rubber balls, ABS plastic washers, and stainless steel screws. Constructed with durable materials for long-lasting performance, offering a stronger alternative to plastic fixtures. Color: Black Material: Rubber, ABS Plastic, Stainless Steel Size: 48mm Package Contents: 4 x Toilet seat fixings Note: Light shooting and different displays may cause slight color variations between the image and the actual item.
