Stainless Steel Phillips Flat Head Screws for Sheet Metal

These corrosion-resistant screws fasten trim, brackets, and other objects with countersunk holes to sheet metal. The head is flat on top and beveled underneath to sit flush with surfaces. Screws have a pointed tip that starts a hole in 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.

Length is measured from the top of the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws withstand harsh weather, salt water, and most chemicals.

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.

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

Steel Phillips Flat Head Drilling Screws

In one step, drill and fasten trim, brackets, and other objects with countersunk holes. These screws have a flat, beveled head to sit flush with surfaces. The Phillips drive withstands less torque than a hex drive, so drill with even, steady pressure.

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.

Corrosion-Resistant-Coated Alloy Steel—The strongest steel drilling screws we sell. They have a coating that is tested to extreme standards, including 1,000 hours of salt spray resistance, to hold up in wet and outdoor environments.

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 Phillips Flat Head Blunt Screws for Sheet Metal

Create a flush finish in sheet metal while reducing the chance of damaging it. These screws have a flat, beveled head for countersunk holes and a blunt tip instead of a point. Drill a hole before installing screws and the fine threads form a vibration-resistant hold. The Phillips drive handles enough torque to keep drivers from slipping.

Length is measured from under the head.

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

Steel Phillips Flat Head Screws for Sheet Metal

Fasten trim, brackets, and other objects with countersunk holes to sheet metal. The head of these screws is flat on top and beveled underneath to sit flush with surfaces. They have a pointed tip that starts a hole in 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.

Length is measured from the top of the head.

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

Stainless Steel Phillips Flat Head Blunt Screws for Sheet Metal

These corrosion-resistant screws sit flush in sheet metal and have a blunt tip to avoid damage. The head is flat on top and beveled underneath to fit in countersunk holes. Drill a hole before installing screws and the fine threads form a vibration-resistant hold. The Phillips drive handles enough torque to keep drivers from slipping.

Length is measured from the top of the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
