What is Screwstock? Types, Materials, and Applications

Screwstock is a type of stock that has a threaded shank, which can be screwed into a tapped hole in a workpiece. The thread on the shank of the screwstock acts as a mechanical lock, holding the screw in place once it has been tightened. Screwstock is commonly used in applications where high strength and precision are required, such as in machinery, equipment, and construction projects.

Screwstock can be made from a variety of materials, including metals like steel and aluminum, as well as plastics and composites. The choice of material depends on the specific application and the properties that are required for the screwstock, such as strength, durability, and resistance to corrosion.

Some common types of screwstock include:

* Machine screws: These are commonly used in machinery and equipment, and are available in a range of sizes and materials.
* Wood screws: These are designed for use in wood and have a coarse thread that helps to secure the screw in place.
* Sheet metal screws: These are designed for use in thin sheet metal and have a sharp point to help pierce the material.
* Self-tapping screws: These have a tapered thread that allows them to tap their own hole in the material as they are inserted.

Screwstock is an essential component in many industries, including construction, manufacturing, and automotive. It is used to secure parts together, hold components in place, and provide structural support. Without screwstock, many of the machines and structures that we use every day would not be possible.
