Steel or stainless steel wood screws have thicker bodies and are typically used for precision woodworking and indoor furniture.
Machine screws are often found in sizes of: 0, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14—the larger the number, the larger the screw.
The smaller the gage number the smaller the screw diameter (opposite of nails and wire diameter).

The size of a screw is extremely important. This determines how much your screw can efficiently hold or anchor. For a safe and accurate application, the screw thickness needs to work for the width of the material you're placing the screw into, in addition to the weight it will have to support.
Wood screws range in diameter from #0 to #24; the larger the number, the larger the size and, unlike wire gauge, #0 is the smallest screw size.
M10-1.0 x 20
Taking a closer look at this description, let's explore its meaning: M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener's length, in millimeters.

Steel bolt with M10 metric thread. Metric threads are designated with a capital M plus an indication to their nominal outer diameter and their pitch: This bolt is M10 x 1.5 - which means the outside diameter is 10mm and the threads are 1.5mm apart (the most common thread pitch for M10).
10mm is larger than 8mm. The second number is the thread pitch. The nut and the bolt need the same pitch.
Shanks and threads come in different sizes. The diameter is indicated by a number. The most common wood screws are number 6, 8, and 10, the larger the number the bigger the thickness.
#10 screw: The diameter on a #10 screw is 3/16 inches, and is typically found in 3/4-inch to 4-inch lengths. This screw is used for general construction purposes, such as building decks and storage sheds. #12 screw: Designed for heavy-duty use—we're talking structural framing—a #12 screw is 7/32 of an inch in diameter.
Type F thread cutting screws is a thread cutting screw with machine screw thread with blunt tapered point, having multi cutting edges and chip cavities. For heavy gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass and plastic.
This is because ACME thread screws and nuts have their own special nomenclature. One example of this special terminology is the designation for different ACME thread forms, which may be labeled as G (General Purpose), C (Centralizing), or Stub.
There are two common types of drywall screw lengths: S-type and W-type. S-type screws are designed for attaching drywall onto metal. Their sharp points make penetrating the surface easier. W-type screws, on the other hand, are longer and thinner. They are designed for installing drywall onto wood.
M6 refers to a metric 6 mm screw. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 1 mm.
Metric threads are used outside of the USA, and commonly in products by HP and other global entities. You can identify an M6 screw by measuring the diameter with a ruler. It'll be 6 mm, or slightly more than 7/32 inches (0.228″).
The first number is the diameter. The bigger the number the bigger the screw. The second number is the number of threads per inch.
