These Forgefix Frame Fixings include both plug and screw with Pozi compatible head. The plug is made from Nylon, for a longer life and durability. Its anti-rotation barbs prevent the plug from rotating in the hole.
The fixings are through fixing, thus eliminating the need for marking and re-positioning. To use, simply drill through both fixture and into the base material tap in the plug, insert the screw and tighten.
