Self-tapping screws for profile

Many structures rely on metal profiles: hobby gardeners use them to set up greenhouses, and profile is also needed for wall cladding in apartments.

Four types of self-tapping screws are used for profiles:

• wafer head — commonly called “seeds” or “bugs” due to their small size. Used to fasten profiles together. Available with sharp points or drill points. Sometimes the underside of the head has serrations so the screw does not loosen under vibration.
• with press washer — suitable for fastening drywall to profile. The wide head ensures a tight fit against the material. Tips are sharp or drill-pointed.
• for drywall — feature a fine thread pitch, which improves the connection with the profile. The head sinks into the drywall when driven in.
• for wood — have a wider thread pitch, which makes it easier to drive into timber.

How to use

First a small-diameter hole is drilled, then the fastener is driven in with a screwdriver or power driver.
