Oh, dude, the effective diameter of a screw thread is basically the imaginary diameter that represents the size of the thread where the width of the thread and the depth of the thread are equal. It's like the Goldilocks of diameters, not too big, not too small, just right for threading stuff together. So, yeah, that's the effective diameter for ya.
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.
the minor diameter should be between 4.917mm and 5.153 mm, so the largest allowable size is 5.153mm
it is what allows the screw to grip into the material its being screwed into. a screw without a thread is a nail
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.
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.
the difference between the min and max effective of your two threads will tell you if there going to clash on assembly

Screws have three main dimensions: diameter, length, and thread pitch. The diameter is the measurement across the screw shaft, the length is how long the screw is, and the thread pitch is the distance between each thread on the screw. These dimensions determine the size and compatibility of the screw for different applications.
It refers to the diameter of the screw. More precisely, it is a 0.138" diameter screw. You can get it in with various head style and thread pitch.
The dimensions of an M3 screw are 3mm in diameter and the thread pitch is 0.5mm.
The dimensions of an M4 screw are 4mm in diameter and the thread pitch is 0.7mm.
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.
To accurately measure the diameter of a screw, use a caliper or a ruler with millimeter markings. Place the screw on a flat surface and measure the distance across the widest part of the screw thread. Record the measurement in millimeters for the diameter.
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.
To determine the size of a screw, you can measure the diameter of the screw thread using a caliper or a screw gauge. You can also refer to the screw's packaging or consult a screw size chart for reference.
