Setup, Compatibility & Care
To install, remove the decorative covers from your existing toilet seat hinges to expose the old bolts. Unscrew the existing nuts and remove the old assembly. Insert the new 9mm bolts into your toilet seat hinge holes, align them with the seat mount, and tighten the square nuts securely from the top. Do not overtighten, as excessive force may crack ceramic or plastic components. For care, keep the area around the hinges clean and dry to prevent mineral buildup; periodically check the tightness of the bolts during your regular bathroom cleaning routine to ensure they remain secure.
