Hanging shelves, lights and equipment in the home requires an anchor in a strong wall and wooden stud. However, there are times when you can't find or use a stud, so you can use wall plugs (anchors) and screws to securely fasten an item to the wall. There are many types of wall plugs and screws, so choose carefully, and then install them with the proper tools.

Determine if you need to use wall plugs, or if you can hang an item on a stud. Purchase or rent a stud finder and mark the locations on your walls. If those areas don't match up with the project, then move on to finding wall plugs and screws that will work.
- Installation in the center of a stud is always preferred, because it is a load-bearing support. Walls, especially dry wall, are not designed to hold large, heavy objects by themselves.
- Wall plugs are designed to hold a certain amount of weight—so, the item you're hanging and the wall assembly you're hanging it on (block, drywall, tile, etc.) will actually dictate what type of anchor you're going to use.

Buy a set of universal wall plugs if your item weighs less than 15 lbs. (6.8kg). If it does, the universal version is likely to work well. If possible, purchase wall plug and screw combos to ensure they will fit.
- If the wall plugs and screws are sold separately, test the screws by inserting them inside the plug. If it fits through the center and comes out the other end with a few mm to spare, the screw will likely work with that plug.
- These universal wall plugs and screws often come with hanging objects in the original packaging.

(200 kg). Unlike the screw head, there is a nut at the end. After the plug is installed, you tighten the nut and the anchor keeps a strong hold on the surrounding material.^{[2]

Unlike other anchors, there are two metal wings. Keep them closed and push them through the ceiling, and then the wings will sit against the inside of the ceiling material while you tighten the screw.^{[3]

Match your power drill bit to the size of the wall anchor. Generally both are measured in mm. For example, a size three wall plug is usually a three mm drill bit. You will be able to compare them side-by-side to ensure the size is right.^{[4]

Unlike nail holes, wall plugs can look unsightly and require patching if you want to change positions.

Warnings

You can't pull wall anchors out once they've been installed in a wall. They are designed to only move in one direction. If you need to remove them, use a small pick or flat head screwdriver to push them through the wall completely. The plug will fall behind the wall and rest on the ground. Proceed to patch the hole in the wall.
