Frequently asked questions

Why choose Tappex KD-nuts?

Tappex KD-nuts provide maximum pull-out resistance and torque strength. Thanks to their clever design with external barbs, the nut "bites" into the material during installation; as the screw is tightened, the sleeve expands for further stability. They are excellent for use in furniture production or technical plastic components where repetitive assembly is required.

• Fast installation: Easily installed by pressing – no tapping required.
• High strength: The expansion function ensures the nut stays secure even under load.
• Non-destructive: Provides a strong thread without splitting brittle materials.
