This resource gives detailed instructions (with illustrations) on how to install a wedge anchor properly. With wedge anchors, it is important to drill accurate hole sizes since these fasteners use friction to work.

2. Use air and a wire brush to thoroughly clear the hole of dush and any other material. Alternatively, clean the hole by moving the drill bit up and down, and suctioning the dust.
3. Using a hammer, tap the anchor into the hole until the washer contacts the item being fixed into the concrete.
4. With correct size socket or spanner tighten anchor to specified torque. Installation complete!
