There are many types of hexagonal screws, including self drilling and self tapping. The hexagonal screws with type17 tip is one of them, called steel roofing screws type17. The difference between it and the hexagonal self-tapping screw is that it has a cut at the end of the steel roofing screws. It is mainly used to connect metal sheets to wood, so it is also called steel roofing screws.
Hexagonal steel roofing screws type17 are self-drilling screws that combine drilling, tapping, and locking functions. They are used to connect two work pieces and are particularly suitable for connecting materials such as sheet metal, thin-walled parts, and wood. To use them, first drill an appropriately sized hole in the material. Then, use an electric drill or screwdriver to insert the hexagonal steel roofing screws type17 and tighten it. The drill tail at the end of the screw works together to form the desired thread and achieve a tight connection.
This kind of metal to wood roofing screws with type17 point is one of the steel roofing screws. The purpose of the groove is to remove chips, because the screw will produce debris during the tapping process, and these debris will increase the resistance of the screw to be screwed in. And this kind of cut-off steel roofing screws with grooves, the debris will be squeezed into the groove during tapping, thereby reducing the resistance of the screw to be screwed in.
In short, such screws are easier to screw in.
Type17 metal to wood roofing screws are generally used on plastics and thin iron sheets. It will be easier to hit it down
Its characteristics are that it has a chip removal effect when tapping wood and plastic, and it is not easy to back off. Compared with ordinary screws, it has high toughness and maintenance, and will not loosen for a long time after assembly. It can be completed in one time using safe punching and tapping, and the operation is simple. Uses: Used to fasten wood and plastic, and can also be used for fixing thin plates in simple buildings.
Main Applications
Sheet Metal Joining: In industries such as construction, automotive, and electrical appliances, hexagonal screws are used to join thin steel and aluminum sheets, enabling fast and efficient assembly.
Thin-Wall Installation: They can be used to join thin-walled metal or plastic components, achieving a secure hold.
Wood Joining: In woodworking, hexagonal screws can also be used to secure wood together, similar to standard self-tapping screws.
