These galvanised countersunk socket screws to DIN 7991 offer a robust and durable fastening solution for demanding industrial and engineering applications. Manufactured from high-strength steel in popular property classes such as 8.8 and 10.9, they provide excellent tensile strength and reliability where secure, flush-mounted fixing is critical.

The precision-engineered countersunk head allows the screw to sit level with or below the surface of the material, creating a clean, snag-free finish that is ideal for assemblies where appearance, safety, or clearance is important. The internal hex drive ensures positive engagement with tooling, reducing the risk of cam-out and enabling accurate tightening to the required torque.

A high-quality galvanised coating delivers superior corrosion resistance, making these fasteners well-suited to use in harsh or exposed environments, including construction, structural steelwork, mechanical assemblies, plant and machinery, and automotive or transport projects. The coating helps extend service life, minimise maintenance, and maintain joint integrity over time.

Compliant with DIN 7991 specifications, these metric socket countersunk screws are designed to meet rigorous industry standards for dimensional accuracy, performance, and safety. A wide range of diameters and lengths is available to support everything from light-duty installations to heavy-duty structural connections.

Choose these galvanised countersunk socket screws when you need a high-strength, corrosion-resistant, and professional-grade fastening solution that delivers reliable performance under high loads and in challenging operating conditions.
