How to use Hollow Wall Anchors


Hollow wall anchors are very popular cavity type fixings for plasterboard, drywall and general board materials.

Hollow Wall Anchors are expansion cavity fixings for use in plasterboard walls and other board materials and thin sheets, the clamping action provides a very strong anchor point spreading the fixture load by deforming to an umbrella shape behind the board and preventing pull-through when tightened.

You install the anchor by placing the hollow wall anchor body and screw into the plasterboard sheet then pull the bolt through the fixing to spread the 4 prongs in the cavity

You can then remove the bolt, now you have a thread anchored into your plasterboard wall.

The hollow wall anchors by Scrooz Fasteners include a low profile zinc plated roundhead screw.


How to install a Hollow Wall Anchor


Step 1 - Mark where you want your anchor point to be:

The pilot hole depends on the size of hollow wall anchor you are using and will be specified by the manufacturer usually on the packaging.

Step 3 - Place the entire anchor into the pilot hole.

Make sure you push the anchor firmly into the wall.

The teeth on the underside of the head must lock into the sheet.

Step 5 - Start to squeeze the trigger on the hollow wall anchor tool.

As you squeeze you will pull the bolt head and thread through the anchor and essentially compress the back of the anchor. As this happen the 4 expansion forks will flare out at the back of the board.

Make sure you squeeze hard, the harder you squeeze the tighter the expansion forks will grip the back of the board. 

Keep in mind to keep the hollow wall anchor tool and hollow wall anchor pressed firmly against the sheet.
