Various elements for connecting parts are used to manufacture furniture items. Self-tapping screws are a popular type of fastener that has its own undeniable advantages. They are especially often used to assemble cabinet furniture, ensuring a solid and durable connection of the parts of the structure.
Self-tapping screws have different types. It is important to select fasteners based on the material and its density, thickness, etc. The type of construction and the desired appearance of the product also influence the selection of self-tapping screws.

What is a self-tapping screw?
A type of fastener such as a self-tapping screw is a type of metal screw with a screw thread and a sharpening or flat end. The head of the element has a notch (straight, cross or polygonal) for screwing it into the canvas. For faster connection of parts of a cabinet or other object for elements with a sharp end, a screwdriver is used (if not available - a screwdriver).
Self-tapping screws are used to fasten parts without or with prepared holes. Due to the thread, the screw is easily screwed into a wooden panel or laminated chipboard. For hidden fastening of furniture parts, an eccentric tie is used, in which self-tapping screws play the main role. As a result of this type of assembly, tables or other items are neat, without external traces of installation that spoil the appearance of the product.
Important! The length of the screws can reach 50 mm and more. Such fasteners are intended for thick panels made of solid wood.
Types of self-tapping screws
Depending on the material and features of the design parts, there are two types of fasteners:
- with rare carving and a sharp end;
- confirmats.
The first type is used for solid wood panels, chipboard, laminated chipboard and MDF. It can vary in length and diameter.
For your information. Short screws are used to assemble narrow panels and plywood.
The second is used to make furniture mainly from wooden boards of sufficient width. It differs in that at the junction of the thread and the smooth upper part, a thickening begins on it. Confirmats often have a flat end and therefore require prepared holes.
Advantages and disadvantages
For furniture assembly, fastenings are of the utmost importance. And the appearance of the product is affected by the possibility of installing a hidden connection.
The advantages of self-tapping screws as fasteners are:
- eccentric coupler;
- neat and reliable connection;
- precision in fitting parts.
If a set of self-tapping screws is used to assemble a furniture structure, then if you work with them carelessly, the following may occur:
- distortions of parts;
- loosening of the fastening when screwed in repeatedly.
How to choose correctly?
When buying screws, it is important to consider many things. The base of screws is steel. Elements with different coatings are used to connect specific parts. When assembling furniture, it is necessary to consider:
- length of fasteners;
- their diameter;
- thickness of the cap;
- carving;
- degree of corrosion (depends on the coating).
| Thread width and height | Application |
| Rare and high | MDF, wood, chipboard, fiberboard |
| Frequent and low | Hardwoods |
| Combined (two-way) | Combined materials (with different densities) |
The color of the fasteners is also important for open connections. In this case, it is worth choosing elements in the same tone as the canvas.
To make a table or cabinet you may need different screws, so it is recommended to consult with the seller if you are going to make the furniture yourself.
The confirmat is used for a more reliable tightening. At the same time, a plug is often made on the head so that the fastener looks more aesthetically pleasing.
Good day. Can you tell me what kind of screw to use to attach the hanging eye to the kitchen cabinet? The size of the cabinet is 1000*700, the eye is reinforced with 4 holes. I would be very grateful.
