Make sure you clean out the hole you've drilled before inserting the anchor. Depending on the load, the screw can be between 3 mm (low load) and 16 mm (high load) longer. So, the higher the load, the longer a screw should be in comparison to the anchor. The longer an anchor is, the greater the load it can bear.
In general, a screw should always be slightly longer than the anchor to ensure it protrudes out from the wall. The wall anchor packaging will usually specify the length and diameter of the screws you should use. The screws you use should then have a slightly smaller diameter of around 4–5 mm, which is opposite to if you're not using anchors (see 1.2). For example, if you used a 6 mm drill bit, you should use the same size anchor. The size of the anchor you need will depend on the size of the hole you’re drilling. And the same rule applies as for drill bits: the anchor must be a good match for the material you’re drilling into. To ensure pictures and shelves remain firmly on the wall, it’s important you use the right wall anchors. We have created a table to help you decide which drill bit is right for your tool. These shanks cannot be used with other chucks such as the three-jaw chuck or other SDS chuck adapters.

A round shank or cylindrical shank fits in almost all drills and impact drills. There are four main types of drill shanks, each of which is suitable for specific tools: There are also various SDS chucks: here the drill bit snaps into place when it's inserted into the chuck, with no need to tighten the chuck or size it to the diameter of the drill shank. By turning the chuck, it can be adapted to the diameter of the drill shank to firmly secure the bit. The different types of drill chucks include a self-centring/three-jaw chuck, which holds the drill bit in place with three "jaws" (points of attachment). The shank is the part that is inserted into the drill chuck. In addition to the various tips, drill bits also differ in terms of their shank shape.
