To use, simply drill through both fixture and into the base material and tap in the Hammer Fixing with a strong blow to complete the fix and ensure full expansion. The screw can be released if required. APPLICATION Widely used for batten, window and door frame fixing. Quick and easy to use - ideal for repetitive installations.
