Lastly，the type of joint being created is also an important factor to consider when selecting the correct wedge, bolt, and drill size. Different joints require different types of fasteners and drilling techniques. For example, a dowel joint may require a dowel and a countersink bit, while a lag screw joint may require a lag screw and a pilot hole. It's important to ensure that you select the correct type of fastener and drilling technique for the type of joint you are creating.

Self-drilling screws, as the name implies, eliminate the need for a separate drilling step, as they have a cutting tip designed to pierce through material without requiring a pilot hole. This not only saves time but also reduces the risk of material damage that can occur with traditional drilling methods. The 1 1 4 self-drilling screws refer to a specific size, which typically signifies a 1/4-inch diameter and a 4-thread pitch. The numbers '1' and '20' often represent the diameter in imperial measurements, while '4' indicates the number of threads per inch.
