S-97595A277 M2 x 6 mm DIN 7991 Brass Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance due to brass construction, ideal for harsh environments and reducing long-term maintenance costs.
• High-strength, reliable fastening with a 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications.
• Efficient and secure installation provided by the 1.3 mm hex drive, minimizing cam-out and tool slippage.
• Precise thread engagement with a Class 6g fit and coarse 0.4 mm pitch, ensuring easy starting and robust hold.
• Flush, low-profile finish from the 90° countersink angle and flat head design, critical for aerodynamic or smooth-surface assemblies.
• Full-length threading for maximum grip along the entire 6 mm shank, enhancing joint integrity.
• Compliance with major regulations including RoHS 3 and REACH, ensuring material safety and global market access.

Professional Applications & Engineering Value

Engineered for precision, these M2 brass flat head screws solve critical challenges in electronics, instrumentation, and marine hardware where corrosion resistance and non-magnetic properties are paramount. The fully threaded design with a Class 6g fit provides superior vibration resistance and load distribution in compact assemblies. Manufactured to DIN 7991, these hex drive screws ensure consistent quality and interchangeability, reducing assembly time and preventing thread stripping. The 90° countersink allows for a seamless finish, making them ideal for applications requiring a smooth surface profile without protrusions.

Specification Summary & Compliance
