There could be several reasons why a self-drilling screw is not working:
- Wrong screw size: It is important to choose the right size of screw for the job, as using a screw that is too small or too large may not be able to effectively drill a hole and create threads in the material.
- Worn or damaged drill point: Over time, the drill point of a self-drilling screw can become dull, damaged or broken. If this happens, the screw will not be able to drill a hole and create threads in the material.
- Insufficient power or torque: Self-drilling screws require a certain amount of power and torque to drill through hard materials, so if the drill or driver used to install the screw is not powerful enough, the screw may not be able to work effectively.
- Hard material: Self-drilling screws are designed to drill into hard materials, but if the material is too hard or thick, the screw may not be able to create a hole or drill through the material.
- Incorrect installation technique: It is important to use the correct technique when installing self-drilling screws, such as holding the screw straight and applying even pressure. If the screw is installed at an angle or with too much force, it may not work effectively.
