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 Flanged Hex Head Thread-Cutting Screws
 |
Cut threads into drilled holes in metal using a nutdriver or socket. Because these screws 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 metal.
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 Torx Flat Head Thread-Cutting Screws
 |
Keep drivers from slipping as you cut threads and secure components with countersunk holes. These Torx screws have a six-lobe recess that’s also known as a star drive. Because they remove material, they take less effort to install and put less stress on your workpiece than thread-forming screws. Their flat, beveled head sits flush in holes.
Length is measured from the top of the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Black Phosphate-Coated Steel—More corrosion resistant than black-oxide steel, these screws are suitable for environments with some moisture. They have a dark, matte coating for a finished look.

Stainless Steel Phillips Rounded Head Thread-Cutting Screws
 |
Drive these corrosion-resistant screws into drilled holes and they cut their own threads. 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.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.

Stainless Steel Flanged Hex Head Thread-Cutting Screws for Metal
 |
Tighten these corrosion-resistant screws 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 metal.
Length is measured from under the flange. Head height includes the flange.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.

Stainless Steel Phillips Flat Head Thread-Cutting Screws
 |
These corrosion-resistant screws cut threads as you drive 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.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.

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.
