Self-drilling anchor screws are a type of fastener that is designed to combine drilling and anchoring into one convenient step. These screws are commonly used in construction, particularly for securing materials to concrete or metal surfaces. The unique design of self-drilling anchor screws eliminates the need for pre-drilling holes, which saves time and effort during installation.

- Thread Design The thread design can influence the screw’s holding power. Coarse threads often provide better grip in thicker materials, while finer threads may work better in softer materials.
