Screw Size Conversion Chart In the metric system, both the diameter of screws and the length are measured in millimeters. The first number in the imperial system is the gauge of the screw which refers to the diameter - the larger the number, the larger the diameter. FASTENERS 101™ Fastener Reference Tables Conversions, Hardness, Thread Pitch, Tensile Strength The tables below are provided as a general guide to help you better understand metric and imperial measurements. Always refer to project specifications and consult an engineer to ensure that your application is appropriate.

Imperial Screw Sizes Explained A wood screw is sized by two different numbers. First is the Gauge of the screw which refers to the diameter - the larger the number, the larger the diameter. A number 4 screw is much smaller than a number 12 screw. The gauge (imperial) is half the imperial diameter (in 16th of an inch) of the screw head, roughly. The precise relationship of imperial screw head sizes and the gauge can be calculated. The formula is as follows: (Head diameter in sixteenths is an inch X 2 ) - 2 = Gauge. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8.

That is often found when trying to match a screw size using Digital Calipers (Inch Decimal to Screw Size) or drill a hole (Screw size to Nearest Fraction) for your project.

Commonly used imperial screw sizes include #2-56, #4-40, and #10-32. Metric screw sizes follow a similar pattern but are measured exclusively in millimeters. They also consist of two parts: a major diameter followed by a pitch value denoting how many threads exist per millimeter. Popular metric screw sizes include M3x0.5, M4x0.7, and M6x1.

Metric and Imperial Conversion, Equivalents, and Alternatives. Fasteners, in general, are available in metric and imperial diameters and lengths.. The most commonly used dimensional units for fasteners are inches and feet. Units to express stress and pressure in the imperial system are pound force per square inch (lbf/in2 or psi); 1,000 psi equals 1 ksi, kilopound force per square inch. One ksi is approximately equal to 6.9 MPa (= N/mm2). The base unit "inch" equals exactly 25.4 mm.

There are two common methods to write the thread dimensions. 1.Thread sizes in inches are specified by diameter and threads per inch. For example, in the screw size 10-24, the first digit refers to the thread diameter, the and second digit is threads-per-inch (TPI).
Those of us of a certain age still refer to screw sizes as imperial - we often hear the words can I have a box of 1"x 8's please? Many manufacturers still market screws that way, but for those of you who find it frustrating buying in metric, here's a handy conversion chart.
