How to Install Drywall Anchors

Screwing something directly into the drywall is not a good idea, because drywall is chalky and will not keep the screw in very tight. If the item is to stay screwed into the wall, it is best to use wall anchors. For most applications, the small blue kind are fine. These will work for securing shelving, hanging pictures, or even just to stick a clock to the wall.

First, use the correct drill-bit size for the application. The size will always be noted on the packaging of the wall anchors. If, for some reason, access to the packaging is impossible, compare the wall anchor to different bit sizes. The middle of the anchor should match the drill-bit size.

Second, installing a wall anchor is the opposite of installing shelving with nails or long screws. The idea is to find the space between the studs, not the studs themselves. Attempting to install a wall anchor on a place where there is a stud behind it could damage the anchor, and make screwing into it a challenge, and compromise its integrity.

Third, be sure to measure before the holes are drilled and the anchors are sunk. This is not only to avoid an ugly wall, but to preserve the integrity of the anchor, too. For instance, if a hole is drilled, and it is later decided that the hole should be a quarter-inch the other way, the wall will NOT be as strong as if there were only one hole. Measure twice, drill once.

Installation

Drill the correct size hole in the correct location. If there is no access to a drill for whatever reason, in a pinch a screwdriver can be punched through the drywall in lieu of drilling. While this may work a few times, the recommended way is always to drill. Consider putting something on the floor to catch the chalky drywall dust.

Place the drywall anchor in the hole and lightly tap it flush to the wall with a hammer or other suitable driving device. Pushing it in past the surface of the drywall can also compromise the strength of the connection, as will leaving some of the anchor sticking out. These anchors expand when a screw is twisted into them, so having it as close to perfect in the wall is a great idea.

Finally, screw the correct size screw into the anchor when it has been properly applied into the wall. If securing metal shelves, for instance, put them against he wall and line the holes up first, then apply the screw. If hanging a clock or picture, leave a small portion of the screw exposed as an attach point.
