Available in Grey and White Colours. Suitable for wood and chipboard screws. M-teeth combined with side-links and screw-guide, ensure entire plug face is forced against walls of the hole, for enhanced grip in soft materials. The wide neck is subject to no expansion pressure and prevents surface damage to tiles and plaster. Side-links stop plug from breaking open during insertion, ensuring positive action when the screw is driven in. Offset block profile allows the plug to hold firmly against sides of a hole when expansion begins. Use with Wood Screws, SS Screws, Machine Screws, etc.
