Wall Plug - Grey Fish HATCH (M10)

Grey fish-type wall plugs in M10, Hatch's own brand. It occupies the useful middle of the heavy end: more grip than the M8 without needing the larger hole the M12 asks for, which matters on a wall you would rather not open up more than necessary. The fish design earns its keep in anything other than solid material - the body bunches and locks behind the face instead of relying on side pressure alone, so it holds where the wall itself is doing very little. Reach for it on wall-hung basins and cisterns, heavier cabinets, boilers and heaters, security grilles and substantial brackets. Drill square, clear the dust, seat the plug flush, and use a screw long enough to run right through the body and set it.
