S-91430A077 M2.5 x 5 mm DIN 963, ISO 2009 Stainless Steel Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh environments and extended service life.
• High mechanical strength and durability offering 70,000 psi tensile strength and Rockwell B80 hardness to withstand demanding loads and prevent stripping.
• Precise and reliable fastening ensured by Class 6g thread fit and coarse 0.45mm pitch for easier alignment and reduced cross-threading risk.
• Flush, low-profile installation with a standard 90° countersink flat head, minimizing protrusion in assembled components.
• Full threading along the 5mm length provides maximum grip and uniform clamping force across the entire engagement area.
• Broad compatibility and standardization through compliance with DIN 963 and ISO 2009, ensuring interchangeability and quality.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting strict global regulatory standards.

Professional Applications & Engineering Value

This M2.5 flat head screw is engineered to address critical challenges in precision assemblies where space is limited and corrosion is a concern. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it suitable for electronics, automotive, and marine applications. The fully threaded design and coarse pitch enable quick installation and secure holding power in softer materials or where vibration resistance is needed. Its flat head with 90° countersink ensures a smooth, flush finish, preventing snagging and maintaining aerodynamic or aesthetic surfaces. Complying with DIN 963 and ISO 2009 standards, this screw delivers consistent performance and reliability in automated or high-volume production environments.
