Similarly one may ask, is a #12 screw the same as 1 4?

A #8 screw size is . 164 fraction of an inch. The diameters listed in the chart below are in fractions of an inch, so the #12 is just shy of 1/4 inch.

Furthermore, how long should screws be? The most important factor in screw selection is length. The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4.

One may also ask, is a #10 or #12 screw bigger?

You can identify a 10-32 screw by measuring the diameter at exactly 3/16″ (4.76 mm). 12-24 rack screws are more common than 10-32 in pre-threaded racks. They are slightly larger and courser than 10-32 hardware. The number “12” is a size designator with no numerical meaning.
