These A2 stainless steel slot countersunk machine screws are precision-engineered fasteners manufactured to DIN 963 specifications (with compatibility to related standards such as DIN 85). Designed for reliability and longevity, they offer excellent corrosion resistance and mechanical strength, making them ideal for demanding environments.

Featuring a classic slotted countersunk head, these screws are perfect wherever a clean, flush finish is required. Once installed, the head sits level with or below the surface of the material, providing a neat, professional appearance and reducing snag points on exposed assemblies.

Manufactured from high-quality 304 stainless steel, these fasteners are suitable for use in indoor and outdoor applications, including engineering projects, machinery assembly, automotive work, construction, marine environments, and general maintenance. Their stainless composition helps resist rust and staining, even in moist or mildly corrosive conditions, ensuring long service life and reduced maintenance.

These machine screws are designed for use with pre-tapped holes or matching nuts and washers, offering a secure and dependable fixing in metal, plastics, and other compatible materials. The slotted drive allows for straightforward installation and removal using standard flat-blade screwdrivers or equivalent tools.
