About this deal
To use self-tapping screws, place the screw directly on the aluminium sheet. The screw's sharp point will make its own hole. Stabilise the screw so it doesn't tilt as it is put in. Let the screw turn until it goes through. Take care not to over-tighten the screw as this can damage the metal or break the screw.

Self-tapping screws are commonly used when you need to attach two pieces of material together where you can only access one side of the material. Where you can access both sides, you can use a screw or a bolt. Self-tapping screws are useful when disassembling and reassembling products such as furniture, as they will insert themselves into the same threads they have been removed from.
Self-drilling screws are available in the same head and drive types as self-tapping screws. You should select your screw type based on the material and finish you require. Below we have outlined some factors to consider when selecting.
