Set Screw

Set screws are unique in that they have no screw head, meaning that they have no protruding part past the threaded shaft: they are thread only with a socket or slotted driver insert at one end. Set screws are used to secure an object within or against another object. Typically they secure a rotating part such as a gear or shaft. Set screws are driven through a threaded hole in the rotating part until it is tight against the inner object, preventing from moving relative to the outer object. Set screws are available with with these points:

cup point

Cup Point 
This is the most commonly used set screw and is identified by a cup-shaped indentation on one end. Cup points are typically used for a quick, semi-permanent or permanent applications where it is acceptable to cut the cup point edge of the screw.

Cone Pointcone point
A cone point is easily identifiable by its sharp cone-shaped point – just like an ice cream cone. Cone point set screws deliver the strongest clamping force due to the deep penetration of the point. As a result they are used for permanent assembly.

flat point set

Flat Point
The cheapest and simplest of the set screw point styles, this screw has a flat surface on the bottom of the screw. This type is used when you need the ability to frequently change parts and require minimal shaft deformation.
