The following table chart defines standard metric external thread size M1.6 to M18 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard external threads. Do not use these values for standard metric internal thread design. All units in mm. These are the M Profile limiting Dimensionings.

09/09/2022 · The imperial diameter (in 16 th of an inch) of the screw head is usually twice the gauge (imperial). Use the formula below to calculate an estimate of the screw head and gauge. Gauge= (Head diameter in sixteenths of an inch X 2 ) – 2. E.g. 5/16 head times two equals 10, minus two equals 8. The Gauge is 8.

A gauge number represents the fraction of an inch in diameter. To know the diameter, you need to refer to a gauge guide to match the gauge with a fraction of an inch. For example, a #0 gauge is 1/16 inch in diameter. A #1 gauge is 5/64 inch, and #2 gauge is 3/32 inch. Lastly, count the threads in one inch to get the thread spacing value.
