What you need to know about furniture screws?

When we install modular furniture or factory production, we use furniture screws. But we are talking about not a single screw but a collection of names of various screws. They also differ from each other. So, what are the types and differences of furniture screws Let's look down together.

So what are furniture screws Simply put, it is the hardware used to connect furniture parts. There are many kinds of specific furniture screws, and the more ordinary furniture connection screws are self-tapping screws, fiberboard screws, and wood screws.

1. Self-tapping screws

A. What is a self-tapping screw

The encyclopedia explains that self-tapping screws, or quick-tooth screws, are quick-install fasteners that are galvanized and passivated on the steel surface. Self-tapping screws are mainly used to connect thin metal plates (steel plates, saw plates, etc.). When joining, first make the threaded bottom hole of the connector, then screw the self-tapping screw into the threaded bottom hole of the connector.

The self-tapping screws used in general furniture are divided into two cases. First of all, the choice of screw type. There are two common self-tapping screws produced by Wang Zi standard parts. GB845 is a pan head screw, and GB846 is a countersunk screw. Simply put, the head of the GB845 is flat, which will be exposed to the outside after fastening, and it is suitable for adding some parts to the furniture. GB846 has an inverted tapered head. When tightening the screw, his head will not be exposed, which is ideal for the internal fixation of furniture so that the screw head and the table surface are flat, not easy to find, and will not affect the beauty of the furniture.

B. Types of self-tapping screws

There are many types of self-tapping screws. Generally, fangs and materials are divided into different types, such as aluminum alloy . Plastic self-tapping screws and there are also hardwood screws. Self-tapping screws are distinguished from ordinary screws in non-metallic or soft metal self-tapping screws, with no bottom holes and tapping; Self-tapping screws are pointed to "self-attack"; Ordinary screws are flat and have the same thickness.

C. Application range of self-tapping screws

1. When fixing the wall panel, the self-tapping screw can be screwed into the wall panel and drilled.

2. Self-tapping screws should be constructed, drilled, tapped, fixed, and locked by special power tools. Self-tapping screws are mainly used to connect and improve thin plates, such as color steel plates and color steel plates, color steel plates and purlins, wall beams, etc.

3. Self-tapping screws are primarily used to install door and window screws.

4. The connection between gypsum wallboard and metal keel adopts wall plate self-tapping screws. The thread is double-ended, the cable has a high appearance of hardness, can be quickly screwed into the keel, and has no prefabricated holes, forming a connection.

D. Precautions for the use of self-tapping screws

Choosing the right cone and a reasonable cutting amount is the key to tapping quality; During the use of self-tapping wire. If the cone is broken, can put the workpiece into the nitric acid solution for corrosion, and the high-speed cone can be quickly eroded without scrapping the workpiece. Correctly choosing the cone will have a completely different effect on the tapping development, attacking many holes. Attack a spot or not attack at all.
