• Next screw the washer on to the top of the through bolt until it is flush with the bolt
• Insert the through bolt into the hole, giving it a gentle tap with a hammer if required until it reaches the end of the hole
• Once inserted you can begin tightening the nut on the anchor until you it clicks. Be careful not to add too much torque as this can affect the quality of the fixing.
