Fastener length is measured from where the material surface is assumed to be, to the end of the fastener. For fasteners where the head usually sits above the 

Brass screws are strong, conductive, and corrosion resistant, with low magnetic permeability. Copper alloy screws have good load capacity, wear resistance, and are suitable for use near magnets. Molybdenum screws have a very high melting point and are exceptionally strong. Plastic screws are inexpensive and corrosion resistant for light loads.

For screws measured in inches, diameters of 1/4 inch and smaller (for machine and sheet metal screws) or 5/16 inch and smaller (for wood screws) are expressed
