Some of the most common sizes are M6, M8, M10 and M12. 'M' stands for 'metric' and the number is the width of the threaded section of the fastener, in millimetres. The measurement is taken between the two parallel sides of the head of the fastener. For example, a ¼” fastener fits a spanner with a ¼” head.

How do you calculate nut size?
Multiply the first number which is the bolt size in inches or millimeters, by 1.5 using a pocket calculator, if necessary. For example, for the numbers in Step 1, 1/2 x 1.5 = . 75 or 3/4, which is the wrench size needed for this standard-sized bolt.What does hex size mean?

Is Whitworth the same as BSP?
BSPT equivalent is NPT and BSPP's equivalent is NPS. NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below.Is UNC and Whitworth the same?
British Standard Whitworth (BSW) It turns out that, except for 1/2" (where the British use 12 threads per inch (tpi) and Americans use 13 tpi) the thread pitches for the rest are the same as for American Unified Coarse (UNC). However, the thread form is different; Whitworth = 55 degrees; UNC = 60 degrees.What metric and SAE sizes are the same?
Metric fasteners are used on imported cars, and SAE fasteners are used on domestic (USA) made cars. Also, they are two completely different systems of measurement. Metric sockets use the metric measurement system i.e., millimeters to describe their size (18mm socket).Is Sae the same as imperial?
SAE is a reference to the American standard sizes for parts and tools. USCS is the American system of units in which SAE standard sizes are measured. Imperial is another system of units formerly used in the UK. Metric refers both to the SI system of units, and also to the current set of standard sizes used worldwide.What does a 36mm socket convert to?
