Product Description

Special anti-expansion design lets the user drive both plug and screw into the hole together without the plug expanding before it is fully inserted. Side-links stop plug from breaking open during insertion, ensuring positive action when screw is driven in. Screw guide stops screw from penetrating sides, by ensuring positive tracking down entire length. M-teeth combined with side-links and screw-guide, ensure entire plug face is forced against walls of hole, for enhanced grip in soft materials. Offset block profile allows plug to hold firmly against sides of hole when expansion begins. Countersunk collar reduces risk of bi-metallic corrosion when fastening non-ferrous fixtures. Nylon material absorbs vibration and noise. Extended expansion length guarantees maximum load-bearing capacity. Advice For installations in perforated and hollow bricks drill with a rotary action only(hammer switched off) Base Material Short expansion plug recommended for use in concrete, natural stone and brick. Extended expansion plug is recommended for use in hollow brick, gypsum aerated concrete and sandstone.
