How to use

To install, first drill a hole into the substrate using a 6mm masonry drill bit, ensuring the depth is slightly greater than the length of the plug. Clean the dust from the hole to ensure maximum friction. Insert the expansion plug until it is flush with the surface of the wall. Place the object to be mounted over the hole, insert the screw through the fixture, and tighten it using a compatible screwdriver until the plug expands fully and the fixture is securely held in place.

What to consider before purchase

• Verify the thickness of the material being mounted to ensure the 35mm screw length is sufficient.
• Check the substrate type to ensure compatibility with standard expansion plugs.
• Ensure you have a 6mm masonry drill bit available for proper hole preparation.

Usage recommendations

For the most secure installation, always ensure the drill hole is perpendicular to the wall surface and free of debris before inserting the plug. Do not overtighten the screw, as this may compromise the integrity of the plug's expansion.
