S-91294A005 M2 x 8 mm DIN 7991 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding industrial environments.
• High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated installations.
• Precision hex drive (1.3mm) allows for secure tool engagement and efficient installation with standard metric tools.
• Fully threaded coarse pitch design enables faster assembly and stronger holding power in various materials.
• 90° countersink angle and flat head profile creates a flush surface finish, ideal for applications requiring aerodynamic or smooth surfaces.
• Class 10.9 strength classification guarantees consistent performance for critical fastening applications.

Professional Applications & Engineering Value

These M2 flat head screws with Class 10.9 strength and black-oxide alloy steel construction address common industrial challenges where vibration resistance, corrosion protection, and high tensile strength are paramount.
