• Wall connections for timber or metal profiles
• Securing cable and pipe clamps
• Mounting thin plaster profiles

Good to know

Install by drilling a 5 mm hole to the required depth, inserting the anchor, and hammering the screw head until the collar sits flush. The countersunk head allows a neat finish without protruding edges.
