Fast installation guide (no plumber required)
- Remove the old hardware: Lift the plastic caps covering the hinge bolts (if present). Use a screwdriver and adjustable wrench to remove the old nuts and bolts.
- Clean the mounting area: Wipe away grime and mineral deposits from the seat hinge and toilet porcelain to ensure a flush fit.
- Fit the new bolts: Insert each stainless bolt through the hinge hole from above, place the metal washer under the bolt head, and press into the toilet seat hinge.
- Secure the nuts: Thread the nylon nuts onto the bolts from below. Hand-tighten first, then finish with a wrench — avoid over-tightening to prevent porcelain stress.
- Check alignment: Lower the seat and tighten only enough to prevent movement. Re-check after a few uses and re-tighten if needed.
Tip: If access is restricted under the toilet, use a low-profile wrench or socket extension. Replace rubber bumpers on the seat if worn for a tighter fit.
Compatibility & usage tips
Designed for universal use with most modern toilets. However, some older models, specialty elongated seats, or integrated bidet seats may require specific fasteners. If your toilet has an unusual hinge spacing or proprietary fastener, measure your current bolt length and thread diameter before ordering.
- Standard hinge spacing: Most household toilets use a standard spacing — these bolts are compatible in the majority of cases.
- For bidet seats: Confirm the clearance and mounting type — many bidet seats use quick-release hinges with different hardware.
Frequently asked questions
- Will these bolts fit my TOTO or American Standard toilet?
- Yes — the kit is designed as a universal fit and is compatible with most TOTO and American Standard models. Confirm your bolt length and hinge spacing for uncommon or older models.
- Are the bolts rust-resistant?
- Yes — bolts are stainless steel with a zinc finish and include metal washers to extend lifespan and resist corrosion.
- Can I overtighten the nylon nuts?
- Avoid excessive torque. Tighten until snug and secure — overtightening can crack porcelain or deform the seat hinge. Re-check tightness after a few days of use.
- How long is the bolt length and thread size?
- Each bolt is approximately 3 inches long with a thread diameter around 0.26 inches (≈6.6 mm). These are approximate — please verify for precise or custom applications.
