Be careful while drilling so that the hole doesn’t get larger than the diameter of the drill bit. Take a piece of cardboard and drill it with a bit that you think is appropriate for the plug. What do you do then? How do you determine which drill bit to use for the wall plug? A simple test could help you determine the drill bit size in such situations. Occasionally, it may happen that the plug isn’t one of the colors listed here. It shows you the corresponding size needed of wall plugs and drill bits for each screw size. Remember we told you we’d share an easy chart matching the drill bit sizes to the wall plugs? Well, here it is. If you can’t choose which drill bit to use, start with a smaller one first to make a pilot hole and work your way up. When your drill bit is slightly smaller than the plug, some light tap with a hammer helps it stick inside with an interference fit. Here you find the best drill bits for the concrete walls. When you want to drill the concrete wall for the wall anchor plug, choose a drill bit that is slightly smaller than the plug itself since you want the anchor to stick inside the drilled hole as tightly as possible. This means there is no standard drill bit that you can install on the wall. The previously mentioned different colored anchors clearly show that not all of them are of the same size or style. This is the part where the size of the drill bit has to be considered. However, metal toggle bolts are sometimes difficult to keep level in the wall while installation. You’ll need to make a pilot hole first to install these bolts into the wall. Toggle bolts are the preferred solution for heavy items since they possess strong holding power. These bolts use the traditional anchor method with two parts: the toggle and the machine bolt. When you drive these bolts into the wall, its metal sleeve expands creating an anchor inside the wall. ![]() Molly bolts are usually made of plastic or zinc-plated steel. The unique thing about molly bolts is that you can remove and reinstall the screw from it without compromising the anchor. Mostly used by professional builders, molly bolts are easy to install and secure. Molly boltsĪlthough these bolts might look similar to the small plastic anchors they can hold many heavy-duty objects. When you drill it, the sharp threaded drilling end flips to press up against the back of the drywall. These anchors can handle very heavy objects. You can screw them without any predrilled hole on the wall. Self-drilling anchors look like screws themselves. Plastic expansion anchors have a good gripping ability of both the screw and the wall. They almost look like a jacket with ribs. Made of plastic, it expands when you drive the screw inside. This is the most commonly used anchor and also tends to be the weakest of them all. So without knowing its types and sizes, you’ll likely make mistakes with drill bit sizes.Īlthough you’ll find some other types apart from these, there are mainly four types of wall anchors. You must be wondering, why do I need to know about wall anchor types when I need to know the size of drill bits? Well, actually the drilling will depend on the size of the wall anchor.

In general case scenarios, yellow plugs are used for 4-8 gauge screws, the red plug goes well with 6-10 gauge screws, 10-14 gauge screws are perfect for brown plugs, and finally blue plug for 14-18 gauge screws.ĭon’t worry if you find it hard to memorize. The length of the wall plug will also have to be the same or a little bit longer than the screw.īut if you’re still confused as to which plug to choose for the screw some numbers might help. It has to be just long enough for the screw to fit in. And if it is too small it won’t fit the screw at all. If the anchor plug is too big the screw will loosen and come off easily. Both need to be compatible in size, otherwise, the plug won’t support the screw. Then you’ll have to pick the correct wall plug which is determined by the screw that you’ve just selected. This is fairly easy since you just need to pick the one that will be able to withstand the weight of the furniture, painting, or anything else that you want to mount. The first order of business is to select the right screw. You don’t want a useless hole to ruin the perfect wall, do you? The drill bit needs to correspond with the size of the screw and wall anchor as well. But don’t just start poking with any drill bit yet and ruin the wall. And when you’ve got a drill in hand, making holes on anything seems just right. When you’re a hammer, everything in the world looks like a nail.
