DIN 912 Screws

Features of DIN 912 Screws:

• Cylindrical Head
  DIN 912 screws feature a cylindrical head that ensures even load distribution and facilitates tightening using the internal hexagon.

• Internal Hexagon
  The screws are equipped with an internal hexagon (hex socket) under the head. This allows the use of a hex key (Allen wrench) for installation and fastening. The internal hexagon provides a more secure grip and prevents tool slippage.

• Material
  DIN 912 screws can be made fr om various materials, such as carbon steel, stainless steel, or other alloys, depending on the requirements for strength and corrosion resistance.

• Application
  DIN 912 screws are often used for fastening the printer frame, installing the print head, adjusting the bed, and other parts of the 3D printer. Their secure fastening and load resistance make them a popular choice for 3D printers.

Size and Thread of DIN 912 Screws:

DIN 912 screws are standard metric screws with a cylindrical head and internal hexagon, available in various sizes and threads depending on the specific project and application.

For example, consider the DIN 912 screw 12.9 M3x8mm:

• 12.9: These digits indicate the strength class of the screw. In this case, "12.9" means that the screw has a very high strength class. The strength class 12.9 indicates a minimum tensile strength of 1200 MPa (megapascals) and a yield strength of 1080 MPa. Screws with this strength class possess outstanding strength and can withstand high loads.
• M3: This part of the marking indicates the diameter of the screw. "M3" means that the diameter of the screw is 3 mm. This is an important parameter, as it determines the compatible threaded holes or nuts for the screw.
• 8mm: This part indicates the length of the screw. "8mm" means that the screw has a length of 8 millimeters. The length of the screw is also an important parameter, as it determines how much material the screw will pass through to create a connection.

Thus, the DIN 912 screw 12.9 M3x8mm has a very high strength class, a diameter of 3mm, and a length of 8 millimeters. These characteristics make it suitable for strong and reliable connections in mechanical systems wh ere high reliability and strength are required.

How to Choose DIN 912 Screws?

The selection of DIN 912 screws depends on the specific requirements of your project where they will be used. Here are some steps to help you choose the appropriate DIN 912 screws:

1. Diameter
   Determine the diameter of the screw that fits your project. This may be M3, M4, M5, etc., depending on the strength and load requirements.

2. Length
   Decide what length of screw you need. Ensure that the length will provide a secure connection between the components of your project.

3. Strength Class
   Consider the strength class of the screw. Higher strength classes, such as 10.9 or 12.9, provide greater strength and may be necessary for machines with high loads.

4. Material
   Choose the screw material based on the environment and needs of the device. Carbon steel and stainless steel are two common options.

5. Thread Pitch
   In most cases, the thread pitch is standard and not a critical parameter for selecting DIN 912 screws, but ensure that it matches your specifications.
