Frequently Asked Questions

Q: What toilet types are these tank bolts compatible with?

A: These M6 toilet tank bolts are designed for standard close-coupled cistern-to-pan toilet configurations — the most common type found in residential bathrooms. Please measure your existing bolt diameter (M6) and compare with your toilet's mounting holes before purchasing to ensure compatibility.

Q: Do these bolts come with gaskets and nuts included?

A: Yes! Each kit includes 2 × complete tank bolt assemblies, with rubber gaskets for both the upper and lower sides plus locking nuts. You get all the hardware needed for a full, leakproof installation right out of the box.

Q: Are the bolts rust-resistant for bathroom use?

A: Absolutely. The bolts are made from stainless steel, which is naturally resistant to rust and corrosion — ideal for the consistently wet and humid environment inside a toilet cistern. The rubber gaskets are also made from high-quality, water-resistant rubber for long-lasting performance.

Q: How difficult is it to install these toilet tank bolts?

A: Installation is straightforward and DIY-friendly. The bottom lock nut design simplifies the process — insert the bolt through the tank and bowl holes, add the rubber grommets on each side, then hand-tighten the nuts. No specialist tools are typically required. Most users complete the repair in under 30 minutes.
