Metric Sizes DIN 7991 A2 Stainless Steel Flat Socket Head

Metric Sizes DIN 7991 A2 Stainless Steel Flat Socket Head Cap Screw

Metric Sizes DIN 7991 A2 Stainless Steel Flat Socket Head Cap Screws are corrosion-resistant, precision fasteners designed for flush-mount applications requiring strength, durability, and a clean finished appearance. Manufactured to DIN 7991 specifications, these countersunk screws feature a 90° flat head and internal hex drive, delivering secure clamping force with a smooth, low-profile installation.

Made from A2 stainless steel (commonly equivalent to 304 stainless steel), these flat socket head cap screws provide excellent resistance to corrosion, oxidation, and moisture exposure, making them ideal for indoor, outdoor, and mildly corrosive environments.

Key Features of DIN 7991 A2 Stainless Steel Screws

Corrosion-Resistant A2 Stainless Steel

A2 stainless steel offers strong protection against rust and environmental exposure. Its chromium and nickel composition forms a passive layer that helps prevent staining and corrosion, making these screws suitable for construction, machinery, architectural, and general industrial applications.

Precision 90° Countersunk Flat Head

The DIN 7991 flat head design allows the screw to sit flush within a countersunk hole. This creates a smooth surface finish that reduces snag hazards and improves overall appearance, especially in visible assemblies and fabricated components.

Internal Hex Drive for Reliable Torque

The socket drive design allows for efficient torque transfer using hex keys or drivers. This ensures secure tightening while minimizing cam-out and installation damage.

Available Metric Sizes & Thread Specifications

Metric DIN 7991 A2 stainless steel flat socket head cap screws are commonly available in sizes such as M4, M5, M6, M8, M10, and M12, with various lengths to meet specific clamping requirements. Standard metric coarse threads ensure compatibility with tapped holes and nuts across a wide range of assemblies.

Common Applications

These stainless steel fasteners are widely used in:

• Equipment manufacturing

• Architectural installations
