S-97715A613 M3 x 8 mm Brass Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ideal for harsh industrial environments.
• Reliable, secure fastening ensured by the Class 6g thread fit, providing excellent dimensional accuracy and consistency.
• High mechanical strength with a tensile strength of 50,000 psi and Rockwell B55 hardness for demanding applications.
• Easy and efficient installation with the 2mm hex drive, allowing for high torque application and reducing tool slippage.
• Low-profile, aesthetically pleasing finish from the rounded button head design, minimizing snagging and providing a smooth surface.
• Wide compatibility with standard M3 x 0.5mm coarse metric threads, simplifying sourcing and replacement.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for regulated industries.

Professional Applications & Engineering Value

This M3 brass screw is engineered to address common challenges in precision assembly, such as galvanic corrosion and thread stripping. The brass material offers excellent electrical conductivity and inherent resistance to rust, making it a superior choice for electrical enclosures, marine hardware, and plumbing fixtures where non-ferrous metals are required. The fully threaded design with a coarse 0.5mm pitch provides maximum grip and pull-out strength in softer materials or pre-tapped holes, reducing the risk of failure. The combination of a rounded button head and hex drive ensures a flush finish that is both visually clean and mechanically robust, preventing snagging in automated production lines. Its high tensile strength and hardness ensure long-term reliability in industrial fastening applications subject to vibration and load.

Specification Summary & Compliance
