Unifix AnkerBolts - Hex Head

A hex flange head self tapping anchor which cuts it's own thread in the base material. Suitable for use in solid concrete, hollow concrete, bricks, dense blocks and most natural stone.

• Simply drill a hole the same size as the Thunderbolt into the material. Ensure the hole is a little deeper than the bolt to allow for dust - see technical info
• Remove any loose dust from the hole
• Screw in the Thunderbolt with a socket wrench. Apply a slight downward pressure to start the self-tapping action, as you would with a woodscrew
• Tighten the Thunderbolt to secure the fixture in place
• Job done
