Extended Product Information

FAQs

What material are these socket screws made from?

These socket screws are made from Grade 12.9 steel, known for its high tensile strength and durability.

What is the thread size and length of this specific product?

The thread size is M12, and the length is 40mm.

What size hex key is needed for these screws?

A 10mm hex key or driver is required for these M12 socket screws.

What does DIN 912 mean?

DIN 912 is a German Institute for Standardization designation for hexagon socket head cap screws, ensuring specific dimensions and tolerances for compatibility.

How many screws are included in a pack?

Each pack contains 50 socket screws.

Are these screws suitable for outdoor use?

While the black finish offers some corrosion resistance, for long-term outdoor use, periodic inspection and potential additional protective measures are recommended due to the nature of steel fasteners.

What is the main advantage of Grade 12.9 steel?

Grade 12.9 steel provides significantly higher tensile and yield strength compared to lower grades, making it suitable for high-stress and heavy-duty applications.

Troubleshooting

Screw is difficult to thread

Ensure the mating thread is clean and undamaged. Check for cross-threading by backing out the screw and re-attempting to thread by hand. Verify the correct thread pitch (M12).

Hex socket is stripping

Ensure you are using the correct size hex key (10mm) and that it is fully seated in the socket. Use a high-quality tool and avoid excessive, sudden force. If the socket is already damaged, the screw may need to be replaced.

Screw breaks during tightening

This can indicate over-tightening or a pre-existing flaw. Ensure you are not exceeding the recommended torque specifications for M12 Grade 12.9 screws. Use a torque wrench for precise application. If the break occurred due to over-tightening, the remaining portion may need to be drilled out.

Pros and Cons

Pros

  • High tensile strength (Grade 12.9) for robust connections.
  • Durable black finish offers corrosion resistance.
  • Standardized DIN 912 ensures broad compatibility.
  • Versatile M12 x 40mm size for diverse applications.
  • Secure socket head allows for high torque application.

Cons

  • Pack size of 50 may be insufficient for very large projects.
  • Specific size (M12 x 40mm) limits use to applications requiring this dimension.
  • Black finish may not be suitable for all aesthetic requirements.
  • Grade 12.9 steel requires appropriate torque settings to avoid damage.

Setup, Compatibility & Care Instructions

Setup:

  1. Ensure the mating threaded hole or nut is clean and free of debris.
  2. Select the appropriate size hex key or driver (10mm for these M12 screws).
  3. Insert the screw and thread it by hand to ensure it is not cross-threaded.
  4. Tighten the screw using the hex key, applying steady torque. For critical applications, use a calibrated torque wrench to achieve the recommended torque specification for M12 Grade 12.9 screws.

Compatibility:

  • These M12 screws are designed to fit M12 tapped holes or M12 nuts.
  • The 10mm hex socket is compatible with standard 10mm hex wrenches and hex drivers.
  • Manufactured to DIN 912 standards, ensuring compatibility with other fasteners and components adhering to the same standard.

Care:

  • Store screws in a dry environment to prevent corrosion of the black finish.
  • Avoid prolonged exposure to moisture or corrosive substances.
  • If used in exterior applications, consider additional protective coatings or periodic inspection.
  • Clean screws with a dry cloth if dust or minor debris accumulates.
