Countersunk head titanium bolt

What is the countersunk head titanium bolt?

The countersunk head screw is also called the flat machine screw, which is a kind of construction part. The head is a 90-degree cone, similar to a common wood screw. The head has a tool-tightening slot, such as a font, cross, hexagon, torx, pentagon, etc.

Screws are used to connect two objects. Generally, the head of the screw protrudes above the surface of the object to be connected, causing the surface to lose its flatness. Countersunk head screws can sink under the surface to make the surface flat. For harder objects, countersunk holes need to be drilled in the corresponding position of the countersunk head. In short, the countersunk head means that the head of the screw can keep the surface flat after installation.

The difference between flat head screws and countersunk screws：

Appearance characteristics:
    

We can see that the shape of the flat head screw and the countersunk head screw are different, and the connection between the head of the flat head screw and the screw is connected with a 90 degree angle. For countersunk screws, it extends from the head of the screw to the screw in a conical manner. The difference in appearance between flat head screws and countersunk screws.

The purpose of the design：

Most of the functions of screw fasteners are used for connection and fastening. We first install the two screws (as shown in the figure below), we will find that the head of the flat head screw is protruding, and the head of the entire flat head screw is exposed, which makes it feel strange to the touch. After the countersunk screw is installed, we will find that almost all the screws are cut into the product. The head of the countersunk screw is flat on the surface of the product, and it feels no different to the touch. Many product shell screws will use countersunk screws as fastening, because they feel better and look more beautiful.

Stress situation：

Due to the difference in the shape of the two screws, the degree of force between the two is also different. Generally speaking, the force of the flat head screw is greater than that of the countersunk screw. Especially when the countersunk head screw is screwed into the object, it is more obvious.
