Office Chair Screw Package

The office chair screw package typically includes screws of various specifications and types to meet the installation needs of different parts of the office chair. Some brands, such as the ErgoHuman BG-HAM office chair, explicitly include a 'tool screw package' component in their product packaging lists. These screw packages are standardized accessories provided by the brand to facilitate user installation. The types of office chair screws available on the market are even more diverse. Common types include:

1. High-strength fasteners: Such as 12.9-grade black internal hexagon set screws and M3/M4 screws. These screws are usually used to connect parts that need to withstand significant pressure, such as the chair back and armrests. Their high-strength characteristics ensure structural stability.
2. Special-function screws: M8*20 black zinc internal and external hexagon screws with anti-slip teeth are commonly used for connecting the five-star base to the gas lift. The anti-slip teeth design prevents loosening. Five-star rubber-headed screws are mostly used for chair wheel installation, and their rubber heads reduce ground friction noise.
3. Chassis-matching screws: Some merchants offer special accessories such as T-type screws for swivel chair chassis and semi-round head internal hexagon screws with pads and embossed patterns. These screws are designed for the connection between the chassis and the seat cushion, and the embossed structure or pads enhance the anti-slip effect.

Screw packages are usually sold in combination, including screws of different lengths, diameters, and head types to fit the installation needs of various parts of the office chair, such as the five-star base, gas lift, chair wheels, armrests, and chair back. For example, M8 screws may be used to connect the five-star base to the gas lift, while M3/M4 screws are used to fix the armrests or chair back adjustment devices.

Purchase recommendations: If you need to replace or supplement screws, it is recommended to prioritize choosing a screw package that matches the original chair model or select compatible products based on the specific component specifications (such as thread diameter, length, and head type). High-strength screws (such as 12.9-grade) are more suitable for load-bearing parts, while anti-slip designed screws (such as those with teeth or embossed patterns) can improve connection stability.
