Check in the Machinery's Handbook 17'th edition on page 1191 through 1193 for a description of all the metric threads as agreed to by the international congress for thread standardization at zurich in 1898.
Thread mills can be used to cut right and left hand threads. Thread mills can also be used for milling and pitching any sizes, including metric and imperial sizes. One can purchase Thread Mills via the official Thread Mill website.
SAE is American or standard thread and metric is everything else. The size or diameter is different and the pitch of the thread is different also.
Yes or metric. I wear a 8.5 inch shoe and a 39 in metric sizes.

A thread gauge is a tool used for identifying the particular thread on a bolt or screw. The gauge will have several blades with saw like teeth of different sizes. You match a particular gauge to the thread which will then tell you what size thread it is. gauges come in various pitches to match different screw threads. UNF, UNC, Whitworth, Metric etc. Each has a different pitch angle and thread per inch or millimetre.An image of a thread gauge can be seen HERE
The thread size of engine bolts and nuts can vary significantly depending on the specific engine model and design. Common sizes include metric threads like M6, M8, and M10, as well as imperial sizes such as 1/4", 5/16", and 3/8". It's essential to refer to the engine's service manual for precise specifications, as using the correct thread size is crucial for ensuring proper fit and function.
The standard faucet thread sizes used in plumbing fixtures are 1/2 inch and 3/4 inch.
Camera lenses come in various thread sizes, such as 52mm, 58mm, and 67mm, which determine the compatibility with different camera bodies.
Metric thread pitch is measured directly from crest to crest of the thread form. For example the distance from crest to crest of a M8 x 1.25 MM thread would be 1.25 MM. Another way to measure it would be linear travel per rotation, in which case a M8 x 1.25 MM thread would travel 1.25 MM each rotation.
Not all spark plugs are metric Normally European cars will have metric spark plugs, but American cars might have an NPT or a UNC thread form, and old British cars might have BSW, BSF or BSP threads. I guess most plugs are metric though as the famous inventor of spark plugs was a Frenchman named champion. you will have heard of champion spark plugs right. the only way to be sure if the thread is metric or not is to measure it standard metric plugs come in the following sizes m10 x 1mm pitch m12 x 1.25mm pitch m14 x 1.25mm pitch m18 x 1.50m pitch good luck
true.
