Key Considerations for Metric Screws

When selecting metric screws, some key considerations include:

1. Size and Thread Pitch: Metric screws come in various sizes and thread pitches, so it is important to choose the right size and pitch for your specific application.

2. Material: Consider the material of the screw based on factors like corrosion resistance, strength, and temperature requirements. Common materials include stainless steel, carbon steel, and brass.

3. Head Style: Different head styles such as pan, flat, or hex are available, each suitable for different applications and tools.

4. Drive Type: Consider the drive type such as Phillips, slotted, or hex socket based on your preference and the tools you have available.

5. Strength Grade: Metric screws come in different strength grades (e.g., class 4.8, 8.8, 10.9, 12.9). Choose the appropriate grade based on the load and strength requirements of your application.

6. Coating: Consider the coating or plating on the screw for additional corrosion resistance or aesthetic purposes.

7. Usage Environment: Take into account the environmental conditions the screws will be exposed to, such as moisture, temperature, and chemicals.

By considering these factors, you can ensure that you select the right metric screws for your specific needs.
