Thread rolling screws create threads in the base material by displacing material. This feature creates a hold with greater strength, more uniform threads, and more durable threads. Thread rolling screws are often more suitable for delicate or brittle base material than thread cutting screws as they are less likely to cause damage or splintering. Fasteners Etc. Inc. offers thread rolling screws as small as a #4 up to 1/4" diameter.
