Compare drilling, pointed, thread-forming, and thread-cutting tips to find the best choice for your material.
Steel Phillips Rounded Head Thread-Cutting Screws
 |
Cut threads in drilled holes as you turn these screws. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.
Length is measured from under the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Black-Zinc-Plated Steel—The dark finish withstands occasional exposure to moisture while creating a finished look.

Steel Phillips Flat Head Thread-Cutting Screws
 |
Cut threads as you drive these screws, and their beveled head sits neatly inside countersunk holes. They remove material to create threads, so they’re easier to install and put less stress on your workpiece than thread-forming screws. The Phillips drive handles enough torque to keep drivers from slipping.
Length is measured from the top of the head.
Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating for a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Steel Serrated Flanged Hex Head Thread-Cutting Screws
 |  |
Serrations on the flange grip material for a tighter, more vibration-resistant hold than other tapping screws. Turn with a nutdriver or socket to cut threads into drilled holes in metal. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. The flanged hex head gives you a high-torque grip and spreads the load to prevent crushing thin material.
Length is measured from under the flange. Head height includes the flange.
