What are the differences between Internal and External threads?
Internal threads are threads inside of a hole in something. Like a nut, for instance. External threads are threads on the outside of a cylindrical object. Like a bolt, for instance. hth, Steve
Tool used for cutting internal threads in a hole?
The tool for cutting internal threads is called a tap. A tool for cutting external threads is called a die.
Internal threads on lathe?
You need an internal thread chaser to do it. They come in a set with the external thread chaser.
How do you make internal and external threads on a metal bar or rod?
Google the following: "tap and die"
What are the purpose of taps and dies?
Taps and dies are are tools for cutting threads in metal. A tap is a bolt like tool for making for making female threads ,a die is a nut liked tool for making male threads. They are used for cutting internal and external threads
What is the area called that the screw goes into The part with the ribs like that you screw the screw down into...?
The hole that you put a screw into is referred to as a "tapped hole". The rib-like things in the hole are called "threads" or, more specifically, "internal threads" as opposed to the external threads on a screw.
Can forging be used for making external threads?
No... threads can't be produced by forging..
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).
What is the difference between 0.5 inch cc and 0.5 inch ips?
IPS- Iron Pipe Size (Threaded Pipe) Standard pipe threads. Female IPS is internal pipe threads, male IPS are external pipe threads. Also known as "NPT" or "NPS". CC- Copper Connection (Soldered, aka Sweat Connection)

What are the advantages and disadvantages of user level threads and kernel level threads?
- USER LEVEL THREADS Aadvantages: · User-level threads can be implemented on operating system that does not support threads. · Implementing user-level threads does not require modification of operating system where everything is managed by the thread library · Simple representation which the thread is represented by a the thread ID, program counter, register, stack , all stored in user process address space · Simple management where creating new threads, switching threads and synchronization between threads can be done without intervention of the kernel · Fast and efficient where switching thread is much more inexpensive compared to a system call - Disadvantages: · There is a lack of coordination between threads and operating system kernel. A process gets one time slice no matter it has 1 thread or 10000 threads within it. It is up to the thread itself to give up the control to other threads · If one thread made a blocking system call, the entire process can be blocked in the kernel, even if other threads in the same process are in the ready state KERNEL LEVEL THREAD: - Advantages: · Because kernel has the full knowledge of all the threads, scheduler may decide to allocate more time to a process having large number of threads than process having small number of thread, where the kernel threads come useful for intense application - Disadvantages: · Kernel level threads are slow and inefficient, since kernel must manage and schedule all the threads as well as the processes. It requires a full TCB for each thread to maintain information about threads, which results in increasing of overheads and kernel complexity
What tool can be used to cut external threads on bolts or rods?
with a pair of scissors
