A faucet may look simple above the countertop. But the real engineering challenge often sits under the sink.
Installing a faucet means securely locking the faucet body to the countertop — usually in a dark, narrow, and crowded space filled with hoses and pipes.

Different brands approach this problem in different ways.

Despite these different solutions, most systems still rely on:
- threaded fasteners
- installation tools
- working in tight under-sink conditions
It raises an interesting question:
What if faucet installation didn’t require tools at all?
At FBT, we approached the problem differently. Instead of improving the wrench, we removed it.
Our patented shank locking nut uses a simple motion:
Push. Twist. Locked.

No tools. Minimal parts. Designed for durability and repeated installation.
Sometimes the most meaningful engineering improvement isn’t visible above the countertop — it’s hidden where installers work the hardest.
What makes it different:
- Unique tooth-piece linkage locking mechanism Maintains secure engagement even on uneven countertop surfaces, preventing accidental loosening or drop-off.

- Snap self-locking structure Push up, rotate, and lock. Once engaged, the mechanism closes automatically and stays fixed.

- High thread torque ≥ 15 N·m Provides long-lasting gripping force without loosening over time — no fall-off, no jamming, no seizing during installation or service.
- Compact size, high versatility Ø32 mm design fits tight spaces and allows multiple hoses to pass through simultaneously, improving installation efficiency.

This design is protected by our US patent (US12264764B2) and developed for manufacturers and brands who care about installation reliability, consistency, and long-term performance, not just assembly speed.
