What is M3.5 Wood Screws?
M3.5 Wood Screws are screws designed specifically for wood and other soft materials. They are self-tapping and can cut threads directly into wood without pre-drilling, providing strong fixing force. The specification is M3.5*35, which means the diameter of the screw is 3.5mm and the length is 35mm. It is suitable for materials that need to be fastened, such as wood, plywood, MDF (medium-density fiberboard), etc. The design of this screw ensures that it can maintain the fastening force under the natural expansion and contraction of wood, and is often used in furniture assembly, construction and DIY projects.
Features
High corrosion resistance: The surface of M3.5 Wood Screws is treated with black zinc electroplating. This surface treatment greatly improves the corrosion resistance of the screws and can maintain a long service life in humid and humid environments. It is suitable for outdoor or other high humidity applications.
Precise size and tolerance: The nominal length of the screw is 35mm with a tolerance of ±0.8mm, and the nominal diameter is 3.5mm with a tolerance of ±0.1mm. Such precise dimensional control ensures the consistency of each screw and will not cause assembly problems due to dimensional errors. Whether in mass production or customized projects, highly consistent products can be provided to ensure perfect matching of screws every time they are used.
Excellent anti-corrosion performance: After 24 hours of salt spray test, the black zinc electroplated screws have extremely strong corrosion resistance and can maintain good performance and appearance even in harsh environments, such as seaside or industrial sites.
Material selection: M3.5 Wood Screws use low carbon steel as the main raw material. Mild steel has good machinability and sufficient strength to ensure the durability and fastening effect of the screws. Mild steel itself has high plasticity and is suitable for manufacturing fasteners that require a certain degree of toughness and strength.
Process Introduction
M3.5 Wood Screws are made with fine craftsmanship, and every link from raw materials to finished products is strictly controlled. First, after the mild steel is cut and formed, it enters the surface treatment stage. In order to ensure better anti-corrosion performance, the surface of the screw will be treated with black zinc electroplating, which not only increases the corrosion resistance of the screw, but also enhances its appearance, making it smoother and with a beautiful black coating. Secondly, the screws are strictly tested in the salt spray test to ensure that they can remain rust-free in a high-salt environment. Finally, each screw undergoes strict dimensional testing to ensure that the size meets international standards such as JIS, ANSI, DIN and BSI.
Specific application range
M3.5 Wood Screws are widely used in many fields. Here are some common application scenarios:
Furniture manufacturing: When producing wooden furniture, M3.5 Wood Screws are often used to assemble furniture such as tables, chairs, bed frames, bookcases, etc. Due to its self-tapping design, installation is easier and saves the step of pre-drilling.
Wooden structure construction: This screw is also widely used in wooden structure construction, such as the construction of wooden houses, wooden fences, wooden platforms, etc. Its self-tapping function enables the screw to penetrate the wood directly, providing a firm connection and not easy to loosen.
Electrical and electronic equipment installation: M3.5 Wood Screws are also suitable for fixing or installing electrical equipment housings, especially wooden electrical housings, equipment cabinets, etc.
DIY and handicraft production: This screw is often used by woodworking enthusiasts and handicraft production to fasten wood together to make furniture, photo frames, models, etc.
Precision
M3.5 Wood Screws have very high precision and strict tolerance control to ensure that the nominal length and diameter of each screw meet international standards. Precise dimensions can effectively reduce installation errors and avoid assembly problems caused by inconsistent screw sizes. Even in mass production, the quality and precision of each screw can be kept consistent, ensuring the stability of the overall installation effect.
FAQ
Why do screws rust?
Although M3.5 Wood Screws are treated with black zinc electroplating and have strong corrosion resistance, rust may occur if the electroplating layer on the surface of the screw is scratched or exposed to an overly humid environment for a long time. To avoid this problem, you can check the screws regularly and avoid exposing them to harsh environments for a long time.
What should I do if the screws are loose?
Wood expands or contracts when the seasons change, which may cause the screws to loosen. It is recommended to check the tightness of the screws regularly and retighten the screws if necessary. If the loosening problem still exists, you can consider using glue to enhance the fixing force of the screws.
What should I do if the screws are difficult to screw into the wood during installation?
A: If the wood is harder, the screw may be more difficult to enter. To avoid this, it is recommended to pre-drill the wood with a drill bit that matches the screw size before installation, so that the screw can be screwed in more easily.
What wood is this screw suitable for?
A: M3.5 Wood Screws are suitable for most softwoods and medium-hard woods, such as pine, fir, birch, etc. If the wood is harder, you may need to choose a larger diameter or stronger screw to ensure a better fixing effect.
Can wood screws of different sizes be customized?
Yes, CHEKSINE METAL, as a Wood Tapping Screw Manufacturer, provides customization services and can manufacture wood self-tapping screws of different specifications and lengths according to customer needs to adapt to different application scenarios and requirements.
