Durable materials for long life: The screw rods and washers are made from high-quality carbon steel with a colorful zinc coating to resist corrosion and wear. POM (polyoxymethylene) plastic nuts and rubber seal rings provide a secure, vibration-resistant connection that prevents leaks and loosening over time. Exact specifications and fit: Each metal screw rod measures 74 mm in length with an 8 mm diameter. Washers and nuts are sized at 22 mm to match standard fittings. The kit is designed to fit all split toilets and is compatible with most standard toilet models. Tool-free, fast installation: No tools required. Insert the POM plastic nut into the mounting hole, position the 22 mm washer and rubber seal, then tighten the screw rod by hand until secure. The design simplifies replacement and reduces installation time. Complete replacement kit: The toilet baghole mounting kit includes two screw rods, two POM plastic nuts, two rubber gaskets, and two washers — everything needed for a stable, reliable toilet seat installation or replacement. Why this kit solves common problems: Replaces corroded or broken bolts to eliminate wobble and noise. Rubber seal rings prevent water seepage and protect the fixture from damage. Zinc-coated steel and POM components reduce the need for frequent replacements in humid bathroom environments. Practical applications: 1. Home bathroom maintenance: Quickly replace worn or rusted toilet seat fasteners to stop rocking seats and prevent damage to the toilet bowl. 2. Rental property repairs: Fast, tool-free fixes between tenants to restore functionality and appearance without specialized tools. 3. Renovation or retrofit projects: Use during bathroom upgrades when reinstalling split toilet seats or swapping seats between compatible models. What to expect in use: A stable, leak-resistant mount with improved corrosion resistance. Hand-tightening capability for easy future adjustments or removals, plus a complete set of matching parts to ensure consistent performance. Compatibility reminder: Designed for split toilets and most standard toilet models. Confirm the 74 mm length and 8 mm diameter suit your fixture if your toilet uses nonstandard fasteners.
