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 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 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.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Steel Phillips Rounded Head Screws for Sheet Metal

The pointed tip starts a hole as you install these screws in sheet metal. They penetrate sheets up to 0.025" thick, but for thicker material you’ll need to drill first. 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.
