A compact locking fastener designed to make toilet-seat installation faster, steadier and less frustrating—without awkward access underneath.

The foldable locking structure passes through the mounting hole, expands underneath and creates a secure anchor point.
The metal locking pieces unfold beneath the mounting hole to create a stable connection and help reduce unwanted seat movement.
The top-mount design makes installation easier in narrow spaces where reaching underneath the toilet is difficult.
The locking contact surface provides a stronger grip to help keep the fastener from loosening during everyday use.
The main metal components use 304 stainless steel for dependable corrosion resistance in everyday bathroom environments.

Insert, release and tighten. The mechanism changes shape inside the mounting hole to create a secure hold.
Keep the metal locking pieces aligned with the support frame before inserting the fastener.
Guide the compact locking fastener through the toilet-seat mounting hole from above.
Turn the screw so the metal pieces open underneath and lock the fitting securely into position.

Important threaded and locking components use 304 stainless steel, while the thickened PP frame guides and supports the mechanism.

The current specification includes both washer sizes—a compact metal washer and a wider protective washer.
Each locking bolt includes one 18 mm washer and one 28 mm washer.

A practical replacement option for many compatible top-fixing toilet-seat installations.
