Benjamin H. ★★★★★

Grabbed a pack for some light-duty trim work and they drive in clean with a Phillips bit, no stripping. The flat heads sit flush nicely and that natural corrosion resistance is a bonus for outdoor spots.

John ★★★★★

The threads are clean and cut smoothly into plastic junction boxes without any binding. Used these for mounting some small brass hinges and they look great with the matching flat heads. Perfect for light-duty decorative work where you don't want rust.

Emma ★★★★☆

The brass finish matches my vintage hardware perfectly, and the Phillips drive grips well without stripping. Only wish the 1-1/2" length came in a smaller pack size.
