Steel Phillips Rounded Head Thread-Forming Screws for Brittle Plastic
 |
Prevent cracking and splitting brittle materials such as phenolic and glass-filled plastic. These screws have alternating high and low threads that minimize stress on your workpiece. 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.

Strong-Hold Drywall Screws for Wood
 |
Alternating high and low threads minimize driving torque and allow the screw to hold more material between threads for a stronger hold and better strip-resistance than standard drywall screws for wood. A curved neck sinks into drywall without tearing the paper surface.
Black Phosphate-Coated Steel—Black phosphate-coated steel screws resist corrosion in dry environments.
Length—Length is measured from the top of the head.

Stainless Steel Phillips Flat Head Thread-Forming Screws for Brittle Plastic
 |
Create a flush finish in brittle materials such as phenolic and glass-filled plastic. These screws have alternating high and low threads that minimize stress to prevent cracking or splitting your workpiece. Flat on top and beveled underneath, the head sits neatly in countersunk holes. The Phillips drive handles enough torque to keep drivers from slipping. Made of stainless steel, these screws resist rust.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.
18-8 Stainless Steel—The choice for wet and outdoor environments. However, these screws won't hold up to the harsh chemicals that 316 stainless steel can.
