Buyer Questions
Frequently asked questions
Sheet metal screw vs self-drilling screw — when to use which?
Sheet metal screws need a pre-drilled hole; self-drilling screws drill their own hole. For thin sheet (under ~1.6 mm) and aluminum, both work but sheet metal screws are cheaper. For thicker steel, self-drilling screws save the pre-drill step. For volume production, self-drilling typically wins on total assembly time.
