What are the screws?

CounterSunk screws are screws designed to fit inside the hole. CounterSink is both a recessed hole and a tool for making a hole that allows compatible screws and screws into the surface. The screwed screws are mostly hidden when they are screwed because their heads are shaped to fit into special holes. When these holes are empty, they look like a normal screw hole with a conical opening at the top; When they are full, the only visible part should be the top of the screw or screw.

Looking in the cross -section, Countersink looks a lot like a standard screw opening. The hole is cut and wrapped in exactly the same way as the standard screw hole. The only real difference is on the very top of the opening, where a specialized piece of machines reduces a conical opening that looks like a funnel in a cross -section. This conical opening allows the ConteSunk screws to screw it into the hole and down into the hole, so the screw head is flush with the surface.

There are two main reasons for using Contresunk screws. The first is to create a smooth surface on the object without protruding the heads of the screws. Some manufacturers do this a step further and using Countersink to complete the screw. Countersink is slightly larger than needed, and the screw ends in the opening; His head is under the surface. The material is located on the screw head and is covered, probably throughout the life of the building.

The second reason for the use of screws is to prevent exposure to sharp edges. When the hole is cut into the material, the edges are often very sharp, especially when cut into metal. The sharper the angle, the sharper it is. The traditional bolt opening is cut at right angle, but the contere -used version used by the Contersunk screws uses a much wider angle, reducing the overall sharpness of the cut. It also removes BURS and color changes made from the token, when the hole for the screw is originally cut.

Countersinking is used in other ways. One of the more common additional uses is the process called Dimpling. The conical holes are placed in a sheet in long rows and columns. This increases the structural stability of the metal and allows the leaves to be pulled on top of each other.
