Office Chair Foot Screws

Office chair foot screws come in a variety of types, with common specifications including M6, M8, and M10. In some special scenarios, slender screws such as 6X35 are used. The following provides an explanation from three aspects: common types, specification characteristics, and application scenarios:

Common Types and Specifications
The core functions of office chair foot screws are to fix the chair feet, adjust the height, or enhance stability. Common types can be divided into two categories:

1. Adjustable Foot Screws: Such as golden stainless steel cap universal swing adjustable feet and stainless steel movable adjustable feet, usually equipped with specifications like M6, M8, and M10. These screws are connected to the chair feet or support structures through threads, allowing users to adjust the height of the feet by rotating them to adapt to different floors or usage requirements. For example, the M6 specification is suitable for light-duty office chairs or coffee tables, while M8 and M10 are used for furniture or shelves with higher load-bearing requirements.
2. Fixed-Type Screws: Such as the 6X35 slender screws used in the installation of W318 connected bow-foot computer chairs, mainly used to fix the chair feet to the chair body structure. In their specifications, '6' represents a thread diameter of 6 millimeters, and '35' indicates a screw length of 35 millimeters. This design allows them to penetrate deeply into the chair foot holes, providing a stable connection.

Basis for Specification Selection
The selection of screw specifications requires comprehensive consideration of load-bearing capacity, installation space, and adjustment requirements:

• Load-Bearing Capacity: M6 screws are suitable for light-duty furniture (such as ordinary office chairs), while M8 and M10 are used for heavy-duty furniture (such as shelves or machine support feet) due to their larger thread diameters and higher tensile strengths.
• Installation Space: Slender screws (such as 6X35) are suitable for scenarios where the chair foot holes are deep or the space is narrow, ensuring that the screws can be fully embedded and fixed.
• Adjustment Function: Adjustable foot screws need to reserve sufficient thread length to allow users to adjust the height by rotating them. Usually, M8 or M10 specifications are chosen to balance stability and adjustment flexibility.

Expanded Application Scenarios
In addition to office chairs, these screws are also widely used in furniture such as coffee tables, cabinets, and shelves. For example, M6 screws are often used in the foot pads of adjustable-height desks and chairs, enabling height adjustment through rotation; M10 screws are commonly found in the adjustable feet of industrial shelves, which need to bear significant weights. Slender screws (such as 6X35) are particularly crucial in the installation of computer chairs. Their length and diameter need to precisely match the design of the chair feet to avoid issues such as unstable fixation due to short screws or restricted movement of the chair feet due to long screws.
