Screw anchors are inserts, typically made from plastic, metal, or fiber, which enable the attachment of screws into brittle materials such as masonry or dry wall.
Are screw anchors necessary?
If you want to hang a picture correctly, so it never falls off the wall, you need to use screws with metal or self drilling plastic wall anchors. If you do not use a wall anchor with the screw, when someone slams a door or something similar happens, the screw will pull out of the drywall and the picture will fall.
What are screw in anchors used for?
Screw anchors are helpful because they allow you to hang items virtually anywhere on your wall without being bound to wall studs, which are typically about 16 inches apart. These anchors expand, clenching into the wall as you install a screw. This, in turn, creates a solid anchor point for secure hanging.
What is a screw wall anchor?
Self-drilling anchors: The anchor is threaded like a screw and has a sharp tip that drives into the drywall surface. The self-drilling anchor threads grip the drywall for a secure fit for drywall anchor installation. The anchor holds in place as the screw is twisted into place.
Do you need screw anchors for studs?
Wood screws directly into a stud are going to be many times stronger then drywall anchors. When you have hit a stud, use a screw. When you are just in the drywall, use a drywall anchor. Drilling out the strong wood to replace with weak plastic doesn’t make any sense.
Can a screw be longer than the anchor?
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.

A wall plug (UK English), also known as an anchor (US) or “Rawlplug” (UK), is a fibre or plastic (originally wood) insert used to enable the attachment of a screw in material that is porous or brittle or that would otherwise not support the weight of the object attached with the screw.
When should you use wall anchors?
Hollow wall anchors work where simple screws won’t. They are designed for use in thin or hollow walls such as drywall, plasterboard, and other board materials that will not support the weight of heavy wall hangings. They normally work by biting into the board or wall and spreading within its cavity to get a fix.

Anchoring With Molly Bolts

Why are my drywall anchors pulling out?
It could be that you are hanging too much weight on the anchors. Drywall and plaster are not designed to carry loads, so applying too much weight to a single point will cause the anchor to come loose. You may also run into trouble if the item you are attaching to the wall is too thick.
