Office Chair Armrest Screws
The common models of screws for office chair armrests are M8 and M6, and the installation methods vary depending on the model and product type. There are various specialized screw products available on the market.

Common Models and Specifications The armrest screws for gaming chairs and some office chairs are mainly M8 and M6. The M8 screw has a diameter of 8 millimeters. Due to its thicker thread, it has a stronger load-bearing capacity and is suitable for scenarios that require withstanding greater pressure, such as heavy-duty office chairs or models with frequently adjustable heights. The M6 screw has a diameter of 6 millimeters and a thinner thread, making it suitable for lightweight designs or scenarios with lower load-bearing pressure, such as home office chairs or children's study chairs. The lengths of both models of screws need to be matched according to the installation gap between the armrest and the chair body, and it is generally advisable to ensure there is no looseness after being fully screwed in.
Differences in Installation Methods The installation methods for armrest screws vary among different models of office chairs. For example, when installing the G101 office chair, the armrest needs to be aligned with the reserved holes on the seat cushion assembly, and fixed using 6 screws (usually of M6 or M8 specifications) to ensure a firm connection between the armrest and the seat cushion. The E06 ergonomic computer chair, on the other hand, uses 4 slender screws (possibly of M5 or custom specifications) to install the armrests, and after installation, four armrest covers need to be placed to hide the screws and enhance the aesthetics. Before installation, it is necessary to confirm that the screw specifications match the holes to avoid thread slippage or structural looseness due to size mismatches.
Characteristics of Market Products There is a wide variety of screw products for office chair armrests on the market, with common types including double-ended screws and carbon steel flat-position double-ended self-tapping screws. Double-ended screws have threads at both ends and are suitable for installation scenarios that require penetrating multiple layers of materials, such as the connection between metal armrests and wooden chair bodies. Carbon steel flat-position double-ended self-tapping screws prevent rotation through a flat-position design, and their self-tapping threads can directly cut into the material without the need for pre-drilling, making them suitable for the quick installation of plastic or thin metal armrests. In addition, color zinc plating can improve the corrosion resistance of the screws and extend their service life. When selecting, it is necessary to comprehensively consider factors such as the armrest material (metal, plastic, wood), installation method (pre-drilling or self-tapping), and usage environment (dry or humid).
