S-98930A024 M6 x 16 mm DIN 603 Carriage Bolts

Key Features & Benefits at a Glance

• Superior anti-rotation performance thanks to the integrated square neck design, which locks securely into materials to prevent spinning during installation and under vibration.
• Exceptional tensile strength with a Class 8.8 rating and 110,000 psi, ensuring reliable performance in high-stress and heavy-duty applications.
• Enhanced corrosion resistance provided by the zinc-plated steel construction, extending the bolt's service life in various environmental conditions.
• Optimized for quick and secure fastening with a fully threaded M6 x 1 mm coarse pitch, allowing for faster installation and a strong hold in wood and metal.
• Consistent dimensional accuracy with a Class 8g thread fit, ensuring reliable compatibility and ease of assembly with standard metric nuts.
• Wide, rounded carriage head distributes load effectively and provides a finished appearance while minimizing surface damage.
• Compliance with major industry and environmental standards including DIN 603, RoHS 3, and REACH, guaranteeing quality and safety for professional use.

Professional Applications & Engineering Value

Engineered for demanding industrial and construction scenarios, this M6 carriage bolt delivers critical performance where vibration resistance and pull-out strength are paramount. The zinc-plated steel material offers a robust defense against corrosion, making it suitable for outdoor equipment, agricultural machinery, and structural frameworks. Its fully threaded metric coarse pitch design ensures deep engagement and rapid installation, while the square neck securely bites into the mounting surface to prevent rotation—a common failure point in dynamic loads. This combination of Class 8.8 strength and anti-loosening features solves key engineering challenges in assembly lines, trailer manufacturing, and wooden structure fastening, providing long-term reliability and reducing maintenance needs.
