How to use sheet metal screws.

Stabilize the screw so it doesn t tilt as it goes in and twist the screw into the metal. A self drilling screw has a chisel tip similar to a drill bit. If these screws are being used the screw can merely be fitted to the drill bit and driven. The metal thickness that you are drilling into needs to be thinner than the length of the drilling point of the screw.

Self drilling or self tapping metal screws increase productivity by reducing the number of steps required to screw together pieces of metal. This kind of fastener features a threaded shank along with a flat rounded head. Be careful not to over tighten the screw since the metal can be damaged or the screw can break. Sheet metal screws can be either self tapping or standard.

Self tapping screws come with a notched tip that acts as a drill bit to drive the screw and keep thin metal from denting. To use self tapping screws place the screw directly on the aluminum sheet. This allows you to skip pre drilling a hole into thinner gauges of sheet metal.
