How To Use Hollow Wall Anchors
Hollow wall anchors are very popular cavity type fixings for plasterboard, drywall and general board materials. Many plasterboard fixings work by biting into the board or expanding into the core material to get a ‘fix’, hollow wall anchors work by expanding in the cavity behind the board clamping the fixture and making a much stronger anchor point. They are a captive fixing which is a great feature and means once its fitted you can remove the fixture and screw but the body will stay in position allowing refitting.
Installation is carried out in 1 of 2 ways, either by using a hollow wall anchor setting tool (one size fits all) or by simply screwing the anchor in using a standard screwdriver or cordless driver. The tool makes fitting the anchors very simple and quick and is ideal when there are several fixings to make or if you are regularly using this type of anchor.
To install using the tool, firstly you need to make sure you have enough space in the cavity to insert the anchor and allow it to expand (so avoid fitting near to studs, corners etc). Start off by drilling the correct size hole in the board and insert the anchor, give it a light tap to make sure the teeth under the head bite into the board (this will stop it turning as its tightened). Insert the nose piece of the tool between the flat collar and underside of the screw as shown above.
