Frequently Asked Questions
Helpful information before you place your order.
Do I need to access underneath the toilet?
These are designed as top-fix expansion bolts and can be tightened from above using a suitable screwdriver. Removing old hardware may still depend on the existing fitting design.
Will these fit my toilet seat?
They are designed for compatible standard top-mounted toilet seats, but fit is not guaranteed for every model. Compare the mounting-hole dimensions, fixing-point spacing and hinge configuration with the product specification image.
How do the rubber expansion bolts work?
Tightening the screw expands the compatible rubber plug inside the mounting hole to help hold the fixing in place. Correct sizing and careful installation are important.
Are the chrome covers rust-resistant?
The product description specifies stainless steel covers with a polished finish, intended for bathroom use. Keep the components clean and follow appropriate care instructions.
Does this package include a complete toilet seat?
No. This listing is for replacement toilet seat hinges and expansion fixing hardware, not a complete toilet seat. Check the package contents and product photos before ordering.
What should I check before installation?
Confirm the mounting-hole diameter and depth, spacing between fixing points, and compatibility with your existing seat and hinge assembly. Tighten carefully and avoid overtightening against ceramic surfaces.
