Sharp and strong
No stripped heads during installation. The self-tapping feature works exactly as described.

Perfect fit
The Phillips head fits snugly in the driver. Great for wood and gypsum board combinations.

Good value
Works well for standard drywall. Box was slightly damaged during shipping but screws were fine.
