How much weight can a cavity anchor hold?
Made from metal, hollow cavity wall anchors feature a screw and a body equipped with contorting fins. The use of a setting tool – also known as a molly setter – is required for these fixings. They can support loads of 20 to 50 kg.
What are the strongest wall anchors?
Traditional metal toggle bolts are the strongest of the bunch, but they’re not the simplest to install because they require drilling a hole that’s approximately three times wider than the diameter of the bolt (necessary to insert the anchor).
Should the screw be longer than the anchor?
Finally, the screw size should match the anchor size. Always purchase the screws and anchors together, because if the screw is too large it will bind in the anchor, and the anchor will twist loose. If the screws are too small, it will not spread the anchor open and secure to the Sheetrock.
Are wall anchors supposed to be flush?
You want the anchor to go in fairly smoothly with a bit of resistance, but you don’t want to be fighting with it to get it to go in. Hammer the anchor in until it’s flush with the wall.
What is hollow wall?

What is the difference between a Molly and an anchor?
Molly bolts may look similar to the small plastic anchors meant for hanging lightweight items, but they are much more heavy duty and more reliable wall mounts. The unique feature of molly bolts compared to other types of wall anchors is that the screw can be removed and reinserted without compromising the anchor.
Can I cut a wall anchor to make it shorter?
If your expansion anchor starts to turn when you’re inserting your screw, you can cut another anchor lengthwise and slide one half of it into the space between the anchor and the side of the hole. As another alternative, you can pull out the anchor and use the next size up.
