DIN 912 / CLASS 12.9 Plain Black Metric Socket Head Cap Screws in stock at Bolts Nuts Screrws
When it comes to securing critical components in industrial machinery, automotive applications, or structural assemblies, the DIN 912 / CLASS 12.9 plain black metric socket head cap screws stand out as a premier choice. These high-tensile screws, known for their robustness and reliability, are engineered to handle demanding environments where strength and precision are paramount.
Why Choose DIN 912 / CLASS 12.9 Socket Head Cap Screws?
DIN 912 is the German standard that specifies the dimensions and requirements for socket head cap screws. The CLASS 12.9 designation indicates that these screws are made from alloy steel with a minimum tensile strength of 1,200 MPa (megapascals), making them one of the strongest fasteners available. The plain black finish adds a layer of corrosion resistance, making them suitable for various industrial and mechanical applications.
Key Features:
- High Tensile Strength: With a tensile strength of 1,200 MPa, these screws are designed to withstand extreme forces, ensuring a secure and reliable connection.
- Precision Engineering: The metric threading and socket head design offer precise fitment and high torque capacity, essential for applications requiring tight tolerances.
- Corrosion Resistance: The plain black finish provides a degree of resistance against corrosion, extending the lifespan of the screw in harsh environments.
- Versatile Applications: Ideal for use in automotive, aerospace, machinery, and structural applications where both strength and durability are critical.
Recommended Torque Settings
Proper torque settings are crucial for ensuring the correct installation of DIN 912 / CLASS 12.9 socket head cap screws. Over-tightening can lead to thread stripping or snapping, while under-tightening can result in a weak joint. Below are the recommended torque settings for various diameters:
- M3: 1.3 Nm (Newton meters)
- M4: 2.9 Nm
- M5: 5.8 Nm
- M6: 9.9 Nm
- M8: 24.0 Nm
- M10: 47.0 Nm
- M12: 81.0 Nm
- M16: 200.0 Nm
These torque values ensure that the screws are tightened to the optimal level, maintaining the integrity of the connection without compromising the screw or the material it’s fastening.
Breaking Strengths
Understanding the breaking strength of these screws is crucial for selecting the right fastener for your application. The breaking strength is the maximum stress the screw can endure before failure:
- M3: 5.7 kN (Kilonewtons)
- M4: 10.3 kN
- M5: 16.6 kN
- M6: 23.7 kN
- M8: 44.0 kN
- M10: 69.5 kN
- M12: 100.0 kN
- M16: 160.0 kN
These breaking strengths highlight the capacity of the screws to handle significant loads, making them suitable for heavy-duty applications.
Hex Key Sizes
The socket head design of these screws requires the use of hex keys (Allen keys) for installation. The correct hex key size is essential for ensuring proper torque application and preventing damage to the screw head:
- M3: 2.5 mm hex key
- M4: 3 mm hex key
- M5: 4 mm hex key
- M6: 5 mm hex key
- M8: 6 mm hex key
- M10: 8 mm hex key
- M12: 10 mm hex key
- M16: 14 mm hex key
Using the correct hex key size ensures a snug fit, reducing the risk of rounding out the screw head or hex key, and allowing for the full application of torque.
