Quick Release Top Fix Toilet Seat Hinge Base with Fixed Mount and Nylon Expansion Plug

Name: Quick Release Top Fix Toilet Seat Hinge Base with Fixed Mount and Nylon Expansion Plug
Brand: Tianyun

This fixed quick release top fix hinge base uses a nylon expansion plug for installation from above, suiting WC pans where access beneath the ceramic is restricted. Tightening the M6 x 80 mm screw expands the plug inside a compatible mounting hole. The 30 mm round base is polished SUS304 and supports selected one-button and dual-button quick release hinges for PP and UF seats. Check hole diameter, depth and ceramic geometry before ordering because the base is not position-adjustable.

Frequently Asked Questions

How does the nylon expansion plug secure this toilet seat hinge?

The plug is inserted into a compatible ceramic mounting hole from above. As the M6 screw is tightened, the nylon body expands against the inside of the hole to hold the fixed hinge base in position.

When should a nylon expansion fixing be chosen instead of a metal toggle anchor?

The choice depends on the mounting-hole diameter, depth, internal clearance and required clamping method. Nylon expansion plugs suit holes designed for radial expansion, while toggle anchors need enough space below the opening to rotate or spread. Confirm the ceramic drawing before choosing.

Which ceramic-hole measurements are important for this expansion plug?

Check the hole diameter, usable depth, wall profile, hole spacing and surrounding ceramic condition. Also confirm that the 30 mm base and M6 x 80 mm screw fit the seat and pan assembly.

Can the nylon expansion plug be reused after removal?

Reuse is not recommended without inspection because an expanded plug may remain deformed or lose holding consistency after removal. For service work, inspect the ceramic hole and use a correctly matched replacement plug when necessary.

Does this fixed base allow hinge-position adjustment?

No. The base is intended for a confirmed mounting position. It is best suited to repeat production or replacement where the seat, hinge and ceramic dimensions are already known.

What should be supplied for an OEM nylon expansion fixing project?

Send the toilet seat and ceramic drawings, mounting-hole dimensions, hinge interface, required finish, expected quantity and any installation test requirements. Samples help verify expansion behavior and assembly fit before volume production.
