The major diameter is the diameter of the crest of the thread. Use a Vernier gage and mesure the diameter of the crest points of contact ( maximum external thread diameter). Unified National thread series defines the expected major diamter and tolerance.
For internal threads ( nuts) the major diameter is the diameter of the roots of the thread.

What is screw thread micrometer?
This is a tool that is used to measure the pitch diameter of a screw. This tool looks like a standard micrometer except that the anvils are specially configured to reach into the screw thread groove and touch the pitch diameter of the screw thread. The screw thread micrometer does not measure any other aspect of the screw thread. It does not measure the: pitch; threads-per-inch; major diameter; minor diameter; flank angles; lead; helix angle.

What were the major inventions that allowed weavers in the textile industry to become mechanized?
Key inventions that mechanized the textile industry included the spinning jenny, invented by James Hargreaves in 1764, which allowed a single worker to spin multiple spools of thread simultaneously. The water frame, developed by Richard Arkwright in 1769, utilized water power to produce stronger yarn. Additionally, the power loom, patented by Edmund Cartwright in 1785, automated the weaving process, significantly increasing production efficiency. These innovations collectively transformed textile manufacturing from handcraft to an industrialized process.

What is diameter of thread?
The diameter of a thread refers to the width of the thread, typically measured across the crest (the outermost part) of the thread's profile. In the context of screw threads, it can be specified as major diameter (the maximum diameter), minor diameter (the minimum diameter), or pitch diameter (the diameter at which the thread thickness and space are equal). This measurement is crucial for ensuring proper fit and compatibility in threaded components. The diameter is usually expressed in either metric (millimeters) or imperial (inches) units.
How do you calculate the depth of a thread?
To calculate the depth of a thread, measure the distance from the crest (top) to the root (bottom) of the thread. This can be done using a thread gauge or caliper. The depth can also be determined by subtracting the root diameter from the major diameter and dividing the result by 2, as thread depth is half the difference between these two diameters. For standard threads, the depth can be found using specific formulas based on the thread profile, such as for triangular threads.
What dimension of the thread is indicated on a screw thread micrometer reading?
The dimension indicated on a screw thread micrometer reading typically refers to the pitch diameter of the screw thread. The pitch diameter is the diameter at which the width of the thread and the space between the threads are equal. This dimension is crucial for ensuring proper fit and function in threaded assemblies. Measurements can also include the major and minor diameters, depending on the specific design and application.
What dimension is a threaded hole with minor diameter about 2.61 and 11TPI?
A threaded hole with a minor diameter of approximately 2.61 inches and a thread pitch of 11 threads per inch (TPI) indicates it is likely a 2.5-inch nominal size with a coarse thread. The actual major diameter can be calculated based on the TPI and the thread profile. In this case, the major diameter would be around 2.75 inches, consistent with standard measurements for 11 TPI threads.
What is the difference between M8 x 1.25 6g and M8 x 1.25 6h?
Metric fastener size designation nomenclature. As fully explained in ISO 965-1, Sect. 5, metric fastener size designations always begin with capital M or MJ followed by fastener nominal diameter and thread pitch, both in units of millimeters (mm), separated by the symbol "x", as follows. M10 x 1.5-6g-S means metric fastener thread profile M, fastener nominal size (nominal major diameter) 10 mm, thread pitch 1.5 mm, external thread tolerance class 6g, and thread engagement length group S ("short"). If referring to internal thread tolerance, "g" would be capitalized. A fit between threaded parts is indicated by internal thread tolerance class followed by external thread tolerance class separated by a slash; e.g., M10 x 1.5-6H/6g.
What are the types of screw threads?
A thread may be either right-hand or left-hand. A right-hand thread on an external member advances into an internal thread when turned clockwise; a left-hand thread advances when turned counterclockwise. If a single helical groove is cut or formed on a cylinder, it is called a single-thread screw. Should the helix angle be increased sufficiently for a second thread to be cut between the grooves of the first thread, a double thread will be formed on the screw. Double, triple, and even quadruple threads are used whenever a rapid advance is desired, as on valves.Pitch and major diameter designate a thread. Lead is the distance advanced parallel to the axis when the screw is turned one revolution. For a single thread, lead is equal to the pitch; for a double thread, lead is twice the pitch. For a straight thread, the pitch diameter is the diameter of an imaginary coaxial cylinder that would cut the thread forms at a height where the width of the thread and groove would be equal.Thread forms have been developed to satisfy particular requirements. Where strength is required for the transmission of power and motion, a thread having faces that are more nearly perpendicular to the axis is preferred. These threads, with their strong thread sections, transmit power nearly parallel to the axis of the screw.

What is the significance of the m5 major diameter in the context of mechanical engineering?
The m5 major diameter is a key measurement in mechanical engineering as it determines the size of the thread on a screw or bolt. This measurement is crucial for ensuring proper fit and functionality of mechanical components, as well as for determining the strength and load-bearing capacity of the fastener.
How do you read a screw thread call out?
This sounds like an easy question, but the answer depends on which type of thread call-out you are trying to read. There are multiple types of screw threads and each has its own call-out; but many are similar in syntax. The most common screw thread style in the USA is the UN-series. These screw threads are specified in ANSI/ASME B.1. An example of a UN-series thread call-out is: 1/4"-20 UNC-2A Decoded it is: Nominal Major Diameter (1/4")-Threads-per-inch (20) Type of thread (UN) Sub-thread-series (C)-Class-of-fit (2A) An example of the M-series thread call-out is: M16x1.5-6g Decoded it is: Type of thread (M) Nominal major diameter (16) Thread pitch (1.5) class-of-fit (6g) For more detailed information here is a link to a nice PDF book which gives very clear basic information on screw threads: http://www.ring-plug-thread-gages.com/ti_starret.pdf. I do hope that you found this information helpful.
