The major diameter of a square threaded screw refers to the largest diameter of the screw, while the core diameter is the diameter of the solid portion between the threads.
The pitch of a square threaded screw is the distance between two adjacent threads and is typically measured in millimeters or inches. It can be calculated by dividing the number of threads by the circumference of the screw.
The mean diameter of a square threaded screw is the average of the major and core diameters. It is an important measurement for determining the strength and load-bearing capacity of the screw.
The major diameter can be measured using a caliper or a screw pitch gauge, while the core diameter can be measured with a special thread micrometer. It is important to measure at the crest of the threads for accuracy.
Yes, the pitch and mean diameter can vary depending on the type and size of the screw. It is important to refer to a screw size chart or consult the manufacturer's specifications to ensure the correct measurements are used.
