Drill Point – The drill point refers to the unthreaded section of the screw. When selecting the screw length, you should account for the length of material you are drilling through. If the threads engage before the drill point length is completely through the material it will result in the screw breaking Aluminium has many positive characteristics that make it easy to work with. When using self-tapping screws on aluminium, choose a self-tapping screw with a drill-like point and sharp cutting blade threads that extend down the whole length of the screw. These self-tapping screws are designed to keep thin metal from denting.

Thread-forming screws join plastic materials together. Due to their design, they grip materials more tightly. Care should be taken as there is a risk of over-tightening the screw, which can result in the joined materials breaking from the pressure

M2 screws are typically used in the manufacture of small items of electrical equipment, laptops, cameras and mobile phones. The “M” designation for metric screws indicates the outer diameter of the screw in millimetres, so for an M2 screw, the outer diameter is 2mm. However, in practice the actual diameter might be between 1.9mm-2mm due to manufacturing tolerances.

They can also be reused in the same material. 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.

M2 screws are available in a wide range of materials including steel, stainless steel, brass, nylon, aluminium and titanium as well as exotic materials including Duplex, Super Duplex and Inconel. Each screw size is described using two numbers – the ‘M’ number and a number indicating the length of the shank, in mm, so M2 screw dimensions of M2 x8, are 8mm long, measured under the screw head.
