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 peak of a screw thread called?
Crest
What a lead screw is used for?
the leadscrew is used for thread cutting on a lathe
What is single thread of screw thread?
when lead of the screw is equal to the pitch it is called single threaded screw

What kind of machine is a thread roll?
A thread rolling machine is used to cut external screw threads on round metal bars to take the internal screw thread of a nut (as in a nut and bolt).
Why feed rod is using in the engine lathe?
The feed rod transmits power from the headstock to the carriage for feeding operations.The lead screw transmits power from the headstock to the carriage for screw thread cutting operations. On some lesser types of lathes the feed rod and the lead screw are used for both the feed and the screw cutting power transmission.
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 lead screw?
It is a screw that has 4 threads wrapping around the shaft ( and 4 starting points) where a standard screw has just one thread that wraps around its shaft. It requires a matching nut. It travels 4 times as far with the same radius of turn so it is 4 times faster to install.
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
