Toilet seat mounting bolts with stainless steel hardware and expanding rubber sleeves Key benefits — why this product matters Longlasting corrosion resistance: Stainless steel bolts and washers resist rust and deformation so the mounting hardware stays reliable over time. Quick, secure fit: The elastic rubber sleeve expands inside the installation hole as the bolt is tightened, creating a tight, stable connection that prevents seat wobble. Quieter use: The rubber sleeve absorbs vibration and reduces friction noise between the seat and bowl for a more comfortable bathroom experience. Simple maintenance: Durable materials mean fewer replacements and less time spent on repairs. What it is and how it works Materials: Stainless steel bolts and washers plus an elastic, flexible rubber expansion sleeve. Function: Insert or fix the expansion bolt into the toilet's mounting hole. Position and align the toilet seat, then insert and tighten the screw. As the bolt is tightened the rubber sleeve expands to press against the inner wall of the hole, increasing friction and holding the seat firmly in place. Performance: The expanding sleeve provides improved grip and stability while the rubber cushions and dampens vibration to reduce noise. Installation (quick steps) 1. Insert the expansion bolt and sleeve into the installation hole. 2. Place and align the toilet seat over the bolts. 3. Insert and tighten the screw until the rubber sleeve expands and the seat is secure.
