Choosing Wall Plugs: Match the Fixing to the Wall

A wall plug is not a one-size-fits-all fixing. Rawlplug’s substrate guide (26 Jan 2024) says to match the plug to the wall material and consider the item being fixed.

Start with the wall

Identify the base—solid masonry, hollow masonry or board—and choose a fixing whose manufacturer lists that substrate and application.

Before drilling

1. Check the exact product sheet for plug length, screw range, drill diameter and minimum hole depth; values vary. For example, Fischer lists a 6 mm drill and 45 mm minimum hole depth for its DuoPower 6 × 30 S. These figures are model-specific, not a universal rule.
2. Check for hidden cables and pipes before making a hole; see Jinnah’s wall-check guide.
3. Use the specified bit and method, and prepare the hole as the maker directs. If the hole is loose, the wall crumbles, or the fixing carries a critical load, stop and seek a suitable recommendation rather than improvising.

Before fitting, confirm the screw and fixture match the exact plug instructions. For advice, contact Jinnah.
