Office Chair Employee Chair Screws
Common screw types for office chairs and employee chairs include hex socket screws, semi-round head knurled furniture screws, screws with metal washers, swivel chair bolts, etc. Some products may use three-in-one connector screws or screws with anti-slip teeth design. The specific choice depends on the chair structure and installation requirements.
Hex socket screws are one of the most common types in office chairs. Their heads are designed as hex sockets and require a hex socket wrench for installation and removal. Common specifications are M6 and M8, suitable for metal frames or connection parts that require high load-bearing capacity. The advantage of hex socket screws is that the surface is flat after installation, not easily damaged by external forces, and can provide strong connection strength, making them suitable for chair structures that require frequent adjustment or load-bearing.
Semi-round head knurled furniture screws have a semi-round head with a knurled texture on the surface, which can increase friction and prevent loosening. These screws are usually used for connecting wooden or plastic parts, such as fixing the chair back to the seat plate. Their installation does not require special tools, and a regular screwdriver can be used, making them suitable for quick assembly or repair scenarios.
Screws with metal washers are equipped with a metal washer below the screw head, which can disperse pressure and prevent damage to the material surface when the screw is screwed in. These screws are often used for connecting metal frames to plastic parts, such as fixing the chair legs to the seat plate. The design of the washer can effectively reduce the risk of loosening and improve the stability of the connection.
Swivel chair bolts are specially designed for the rotation function and are usually used to connect the chair seat to the gas lift or the five-star base. These bolts need to have high wear resistance and fatigue resistance to ensure smooth rotation after long-term use. Some swivel chair bolts may use special coatings or materials to extend their service life.
Three-in-one connector screws are commonly used in chair structures that require concealed installation, such as connecting the chair back to the seat plate. These screws achieve seamless installation through a combination of embedded parts, connecting rods, and nuts, resulting in a neater appearance. However, the installation process is relatively complex and requires precise alignment of the embedded holes.
Screws with anti-slip teeth design have anti-slip teeth added to the threaded part, which can enhance the friction between the screw and the material and prevent loosening. These screws are suitable for parts that require frequent adjustment or vibration, such as the chair back angle adjustment mechanism, and can effectively improve the reliability of the connection.
