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.

What exactly is a thread mill used for?
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 and metric What is the difference?
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.
Do shoe sizes go by inches?
Yes or metric. I wear a 8.5 inch shoe and a 39 in metric sizes.
What is the standard angle for ISO metric thread?
60°
WHAT IS 24 UNF THREAD PLUG GAUGE?
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
Are telescoping gauges available in metric and imperial sizes?
true.
How is metric thread pitch measured?
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.
Why are spark plug threads metric?
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
What are the benefits of metric system over the English system?
The metric system makes more sense because it uses planned out sizes instead of random sizes that don't correlate with each other.

How do you read dimensions of bolts I am trying to sell motorcycle fairing bolts I have a lot and I found somewhere that shows the sizes but how do you measure the metric bolts they say 6x14 6x16?
The first number is the diameter of the bolt in millimeters and the second is the length in millimeters.So just like a 1/2 x 6 US bolt is 1/2 inch in diameter and 6 inches long...a 6x14 metric bolt will be 6 millimeters in diameter and 14 millimeters long.There is another measurement you may have to worry about with larger sizes. Namely the thread pitch. In metric you typically only see fine thread bolts starting at 8mm (8 millimeter diameter) and up.You may see measurements like 8 x 1.0 x 40. This would be an 8mm diameter bolt 40mm long with a 1.0 thread pitch. The standard pitch for 8mm bolts is 1.25 so this would be a fine thread bolt.
What is 38 SAE J475?
SAE J475 is a specification for thread sizes on tubing. 38 may be a typographic error for a 3/8" thread.
