What is half-nut mechanism?
A half nut is literally a nut split in half, length wise and makes up the basic half-nut mechanism. Such a mechanism is typically found on a engine lathe. This mechanism can be "open" or "closed" and when closed clamps onto the lead screw of said lathe. This forms a connection between the apron of the lathe sliding on the ways. The apron carries the cross and compound slides, the latter in turn holds the cutting tool. When closed, or "engaged", the movement of the apron moves relative to the rotation of the lead screw. This lead screw is precise in nature and can be described in terms of threads per inch (or per meter or millimeter in case of metric). The lead screw is also connected somehow (there are various methods) to the main motor of the lathe and this ratio of gears can be changed so that many variations of threading, all relative to the thread of the lead screw, can be accomplished on the workpiece being turned/threaded by the screw cutting operation. On a basic older style lathe, the screw begin cut can not be cut in a single pass of the cutting tool. This means that the half-nut may need to be disengaged to reverse the direction of the apron allowing for the cutting operation to be repeated, each time engaging and re-engaging the half nut, until the depth of the screw being cut has reached a final thread depth.
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.
Why is graphite used in making pencil leads?
Lead was used at one time, but lead is poisonous. Children, especially, were poisoned by sucking on their pencils. So graphite was substituted for lead and works very well. Graphite may be superior to lead because it can be made with difference degrees of hardness. I do not know about the relative costs.

What is an example of a lead screw?
screw
What are the uses of leadscrew?
A lead screw is used to transfer circular motion into linear motion as the lead screw engages with a nut
What is single thread of screw thread?
when lead of the screw is equal to the pitch it is called single threaded screw

What works better a screw or a nail?
a screw works better cues it has threads and a nail is just goes straight in the board. The nail is stronger but the screw holds tighter.
How does a screwdriver driver works?
You insert the point into an appropriate screw and rotate the handle clockwise to screw in and the opposite to screw out.
What is the function of a lead screw in a lathe machine?
The lead screw moves the turret by a precise increment for every rotation of the screw. This allows the machine to generate threads in a workpiece, to generate precise length and diameter dimensions, and to maintain a constant rate of metal removal.
Is a lead screw reversible?
presuming you mean the lead screw on a lathe, used when cutting threads on the workpiece, then the screw itself is obviously fixed, but the rotation of it may be able to be changed, depending on the lathe manufacturer.
Where would a lead screw be found?
Sometimes the propeller on a boat is called a screw & they used to be made of lead. So they would be found at the end of the propeller shaft.

When was Maryland White Lead Works created?
Maryland White Lead Works was created in 1867.
Does the length of threads on a screw make a difference on how well it works?
no
