Wood screws have large threads for use in wood.
Wood screws
Phillips flat head
Flat heads are countersunk (cone shaped under the head) with a flat top. Phillips drive is x-shaped for installation with a phillips screw driver.
Stainless steel 18-8
A corrosion resistant steel alloy. The most common stainless steel for general hardware use.

Stainless steel 316
A corrosion resistant steel alloy. A highly corrosion resistant grade of stainless steel. Ideal in salt water and chlorine environments. More expensive than 18-8.

Zinc plated steel
A low carbon steel for general use. Zinc plated for moderate corrosion resistance.

Brass
Solid brass. An alloy of primarily copper and zinc with good corrosion resistance. Used mostly in decorative and electrical applications. Exact color varies.

Frearson flat head
Flat heads are countersunk (cone shaped under the head) with a flat top. Frearson drive is x-shaped, similar to (but not compatible with) phillips.
Silicon bronze
Solid bronze. An alloy of copper with greater strength and corrosion resistance than brass. Exact color varies.

Slotted flat head
Flat heads are countersunk (cone shaped under the head) with a flat top. Slotted drive has a simple slot for a flat bladed screw driver.
Stainless steel 18-8
A corrosion resistant steel alloy. The most common stainless steel for general hardware use.

Zinc plated steel
A low carbon steel for general use. Zinc plated for moderate corrosion resistance.

Brass

Silicon bronze
Solid bronze. An alloy of copper with greater strength and corrosion resistance than brass. Exact color varies.

Slotted oval head
Oval heads are countersunk (cone shaped under the head) with a rounded top. Slotted drive has a simple slot for a flat bladed screw driver.

Silicon bronze
Solid bronze. An alloy of copper with greater strength and corrosion resistance than brass. Exact color varies.

Phillips round head
Round heads are domed and look like half of a sphere. Phillips drive is x-shaped for installation with a phillips screw driver.

Square flat head w/ nibs, type 17
Type 17 screws have an auger point. Countersinking nibs aid in material removal. Flat heads are countersunk (cone shaped under the head) with a flat top. Square drive is designed to reduce the risk of cam-out (stripping) and allow single-handed installation.
Zinc plated steel
A low carbon steel for general use. Zinc plated for moderate corrosion resistance.

Lubricized finish steel
A low carbon steel for general use. Lubricized to ease installation.
