Suki Socket Head Cap Screw M8x20 DIN 912 A2-70 Stainless Steel 4 Pieces

The Suki Socket Head Cap Screw M8x20 is a high-quality fastening solution engineered to meet the DIN 912 standard. These screws are crafted from durable A2-70 stainless steel, providing exceptional resistance to corrosion and environmental wear. Designed for precision and reliability, this set of four screws is an essential component for mechanical assemblies and construction projects where a secure, high-torque connection is required.

Advantages

The primary benefit of these socket head cap screws is their superior material composition, which ensures long-term performance even in challenging conditions. The A2-70 stainless steel grade offers a balance of strength and rust resistance, making them suitable for both indoor and outdoor use. The socket head design allows for high torque application using a hex key, ensuring a tight and secure fit that is less prone to slipping compared to traditional slotted or cross-head screws. Their standardized dimensions ensure compatibility with a wide range of pre-drilled or tapped components.

Suitable for

• Mechanical engineering and machine assembly
• Construction and structural framing projects
• Furniture manufacturing and assembly
• Automotive repair and maintenance
• Projects requiring a flush or recessed finish

When it may not be suitable

These screws are not recommended for high-stress structural applications that require specialized high-tensile steel grades beyond the A2-70 specification. Additionally, they may not be suitable for environments with high concentrations of chlorides, such as marine or coastal areas, where A4 grade stainless steel would be preferred to prevent pitting corrosion.

Key specifications

• Thread diameter: 8 mm
• Length: 20 mm
• Material: A2-70 Stainless Steel
• Standard: DIN 912
• Drive type: Hex socket (Allen key)
• Quantity: 4 pieces

How to use

To use these screws, ensure that the receiving hole is properly tapped to match the M8 thread size. Align the component to be fastened and insert the screw into the hole. Use a compatible hex key to tighten the screw until the head is flush with the surface or the desired torque is achieved. Avoid over-tightening to prevent damage to the threads or the tool interface.

What to consider before purchase

• Verify the thread size and length requirements for your specific application.
• Ensure you have the correct size hex key for the socket head.
• Check if the A2-70 stainless steel grade is appropriate for your specific environmental conditions.
• Confirm the quantity required for your project, as this pack contains 4 pieces.

Usage recommendations

For optimal results, it is recommended to use a calibrated torque wrench or a high-quality hex key to prevent stripping the socket. If installing into metal, applying a small amount of anti-seize lubricant can help prevent galling, which is common with stainless steel fasteners.
