A self-drilling drywall anchor 1 comprises a shank having an internal bore extending from a first end of the shank to a second end of the shank, an external thread provided on the shank and a screw drive 16 provided at the first end of the shank, the screw drive 16 being configured to engage with a tool for applying torque to the shank. In use, applying torque to the shank via the screw drive 16 enables the external thread to cut a helical groove into a drywall panel to secure the anchor 1 to the panel. The screw drive 16 comprises a clutch 3 configures to limit the torque transmitted to the shank by a tool engaged with the screw drive 16. |
