How to use

Drill a hole of the correct diameter and depth for the 8x40 wall plug, clean the hole from dust, insert the plug flush with the surface and drive the appropriate 8 mm screw until the fixture is secured. For hollow substrates, ensure the plug expands and engages behind the surface; for solid substrates, confirm the plug's ribs and segments are fully seated to provide grip. Select a screw length that provides adequate thread engagement while leaving the required thickness for the mounted item.

Usage recommendations

Use a drill bit matching the plug diameter and verify substrate suitability before installation. For heavy loads or safety-critical fixings, follow applicable building standards and consider using metal anchors or chemical anchors where specified. Store the box in a dry place to prevent dirt and moisture from affecting plug performance.
