Suki Socket Head Cap Screw M5x20 DIN 912 A2-70 Stainless Steel 6 Pieces

The Suki Socket Head Cap Screw M5x20 is a high-quality fastener engineered to meet the DIN 912 standard. These screws are crafted from A2-70 stainless steel, providing reliable performance and significant resistance to corrosion in various environments. Designed for precision, they feature a cylindrical head that allows for a flush fit when installed in countersunk holes, ensuring a clean and professional appearance for your mechanical or construction projects.

Advantages

The primary benefit of these stainless steel screws is their superior durability and resistance to rust, making them suitable for both indoor and outdoor applications. The socket head design allows for high torque transmission when using a compatible hex key, which minimizes the risk of slippage during installation. Because they adhere to the DIN 912 standard, they offer consistent dimensions and reliable mechanical properties for demanding assembly tasks.

Suitable for

• Mechanical engineering and machine assembly
• Construction and structural fastening
• DIY projects requiring high-strength connections
• Outdoor equipment maintenance where corrosion resistance is needed

When it may not be suitable

These screws are not recommended for applications involving high-salinity environments, such as direct marine or coastal exposure, where marine-grade A4 stainless steel would be required. Additionally, they should not be used in high-temperature environments that exceed the thermal limits of A2-70 stainless steel.

Key specifications

• Material: A2-70 Stainless Steel
• Standard: DIN 912
• Diameter: 5 mm
• Length: 20 mm
• Drive type: Hex key (socket)
• Quantity: 6 pieces

How to use

To install the Suki socket head cap screw, ensure that the receiving hole is properly threaded to match the M5 diameter. Align the screw with the hole and use an appropriate hex key to tighten it. Apply steady pressure to ensure the screw sits flush against the surface. Avoid over-tightening to prevent stripping the internal hex drive or damaging the threads.

What to consider before purchase

• Verify that the M5 thread size is compatible with your existing equipment or pre-drilled holes.
• Ensure the 20 mm length is sufficient for the thickness of the materials you are joining.
• Confirm that the A2-70 stainless steel grade meets the environmental requirements of your specific application.

Usage recommendations

For optimal results, use a high-quality hex key that fits snugly into the socket to prevent rounding the internal drive. If installing into metal, consider using a thread-locking compound if the assembly is subject to significant vibration.
