A tek screw, also known as self-drilling screw, is equipped with a drill-like point that allows it to create its pilot hole as it is driven into materials. This eliminates the need for pre-drilling, which can streamline the construction process significantly. The 5 designation typically refers to specific measurement protocols related to the screw's dimensions and strength characteristics. However, the specific meaning of 5 often involves manufacturer specifications or industry standards, allowing for slight variations in size and application based on regional or production practices.

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.
