S-91306A659 M4 x 6 mm ISO 7380 Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable performance under high-stress conditions, reducing fastener failure in demanding applications.
• Superior corrosion resistance from zinc-plated alloy steel construction prolongs service life in harsh industrial environments, minimizing maintenance needs.
• High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated assembly and disassembly cycles.
• Coarse thread pitch (0.7mm) enables faster installation and superior vibration resistance compared to fine-thread alternatives.
• Precision Class 6g thread fit guarantees consistent engagement and optimal clamping force distribution across connected components.
• 2.5mm hex drive with rounded button head combines secure tool engagement with a low-profile design that minimizes snagging hazards.
• Full threading along the 6mm length maximizes grip range and load distribution capabilities for versatile application requirements.
