To properly countersink a screw for a flush and secure installation, follow these steps:
- Choose the right size drill bit for the screw head.
- Drill a pilot hole for the screw.
- Use a countersink bit to create a conical-shaped hole for the screw head to sit flush.
- Adjust the depth of the countersink to match the screw head.
- Insert the screw into the countersunk hole and tighten it securely.
