Allen (hex socket) drive is a six-sided recess for use with an allen wrench (hex key).A set screw is a unit of hardware designed to fasten one object inside of another. The set screw prevents relative movement between the two objects, which allows each to function as intended.
The avaliable material : stainless steel, carbon steel , alloy steel
Set screws are generally fastened using an internal mechanism rather than a traditional external head. The top of the screw may be slotted for use with a screwdriver, or may have a hexagonal shape.The most common is the cup point, which is slightly cupped to meet the surface of the inner object. It is used for permanent or semi-permanent installations, and provides a high level of security and control.These screws are also used in many industrial and mechanical devices, especially rotating items such as pulleys or wheels.The Cup Point digs into the contact surface for maximum holding power under pressure. The Knurled Point features better locking power than the standard Cup Point.The fastening action is by friction between the screw and the shaft, often (but not always) with some amount of elastic or plastic deformation of one or both.
The pointed end of a set screw with different features in a variety of different shapes depending on the application. The most common is the cup point, which is slightly cupped to meet the surface of the inner object. They are used for permanent or semi-permanent installations, and provides a high level of security and control.
According to Application Point selection is normally determined by the nature of the application, their relative hardness, frequency of assembly and re-assembly and other factors. Reviewed here are standard point type, their general features and most frequent areas of application of each type.
The most common type is the cup point. This type works well because the surface is rounded so that a small surface area is in contact, but it does not have extremely high stress at one point like that of a cone point.
