Hollow Wall Anchors

Hollow Wall Anchor is designed to provide a secure fastening into hollow cavity walls such as plasterboard or plywood.  The body of the anchor remains securely fixed in the wall even if the screw is removed. This provides an ideal fixing point for fixtures requiring periodic removal, such as shelving, curtain fixtures and light fittings. Please see attached table on each item for grip range, drill size and hole depth.




Hollow wall anchor is a lightweight two-part plasterboard/drywall fixing which opens the umbrella flaps on the other side as you screw a fastener into it. The housing of the anchor has 4 flaps which are dented in the middle. The flange has 4 sharp teeth facing towards the flaps which are to be embedded into the plasterboard. The neck is the cylindricalpart below the flange which is the grip size of the anchor.


The It works on the similar principle as a pop rivet. You drill a hole put the anchor through the hole with the flaps inside the hole. As you screw the machine screw in the middle the anchor’s housing is pulled forward and hence opening the flaps behind like an umbrella, to hold onto the plasterboard. It is difficult to fix anything to a plasterboard as its hollow and comparatively soft. You must find a stud behind the wall and use a timber screw but that limits you and its difficult to find the stud as well. The hollow wall anchors are extremely easy to use and are very handy for light duty fixes.


They can be installed using a hollow wall anchor gun as well. Once you put the anchor in the pre-drilled hole you hook the head to the gun, and it will pull the bolt clamping the anchor. It is a quicker way of installing the anchor than screwing it manually.


Another advantage of the hollow wall anchors is that you can unscrew the bolt as the anchor is fixed and will not drop behind as it does with the spring toggle. Also, with the spring/wing toggle you must drill a big enough hole to get the wings in which can result in a bit loose fixing in the end.


Hollow wall anchors are immensely popular with electricians, plumbers, construction workers, cabinet makers, frame workers and other miscellaneous trades. Most common use of them is installation of light weight brackets or hooks, electrical fittings or sockets installation, clips or clamps installation, etc.

How To Install

Drill a hole in the plasterboard with respect to the size of the anchor being used. Make sure the hole is as close as it can be to the anchor size. If the hole is too big the tooth on the flange will be close to the edge and rip through it making the hole bigger.
If using a hollow wall anchor gun, hook the head of the screw on the slot on the gun and squeeze the grip until the anchor is fully pulled. Once its secured used the trigger to release the head
Unscrew the bolt from the anchor and put a bracket or anything between the two in so that when you are screwing the bolt, the anchor does not rotate with it. The bracket or a washer will act as a locking mechanism.
Put the anchor in the hole and with thumb press the teeth on the flange into the plasterboard.
Start to screw the bolt in slowly as you do it will pull forward and the umbrella flaps will start to open screw it until they are fully open and secured.  
Unscrew the bolt again to take the washer or bracket out.
The anchor will be held at the back and now you can apply the load onto it and fix it with the bolt.
