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.
Why square threads are used in a screw jack?
§ Screw threads have better compression strength than other threads. § Due to low thread angle there is no radial pressure on nut. § Due to smaller angle, the lead of screw is less.
What is the function of screw thread?
it is what allows the screw to grip into the material its being screwed into. a screw without a thread is a nail
What is the relationship between a nut thread and a screw thread?
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.
What is the Thread used in lead screw?
An acme thread is the most commonly used.
Angle of thread for different thread?
The angle of a thread of a screw is an angle between the threads and it is the defining factor for the shape of the screw thread.

What is a Helix shape?
A helix is a three-dimensional curved shape that resembles a corkscrew or spiral. It is formed by a curved line wrapping around a central axis. Helix shapes are often found in nature, such as in DNA molecules or certain types of shells.

What is a helix screw?
helices are a style of vase painting developed in Corinth in the early 7th and 6th centuries b.c characterized chiefly by human and animal and ornamentally motifs painted boldly in a black figure style
What is the difference between thread angle and lead angle also clear it from diagram?
A thread angle is the angle of the threads relative to the shank which is 60 degrees for unified screws The lead angle is the pitch of the screw divided by the circumference of the shank; it varies but is around 3 degrees

What is angle of helix in helical spring?
The angle which the axis of the spring wire makes with the horizontal line is known as helix angle.
What is single thread of screw thread?
when lead of the screw is equal to the pitch it is called single threaded screw
What is the function of screw thread?
it is what allows the screw to grip into the material its being screwed into. a screw without a thread is a nail
Thread used in screw jack?
acme thread
