S-97248A322 M8 x 35 mm DIN 603, ISO 8678 Carriage Bolts

Key Features & Benefits at a Glance

• Superior anti-rotation performance thanks to the integrated square neck design, which securely locks into materials to prevent spinning during installation and under vibration.
• Excellent corrosion resistance provided by 18-8 Stainless Steel, ensuring long-term reliability in humid, outdoor, or chemically challenging environments.
• High tensile strength of 70,000 psi delivers robust load-bearing capacity, making it suitable for heavy-duty structural and industrial applications.
• Fully threaded coarse pitch (M8 x 1.25mm) allows for faster installation and provides strong holding power in a wide range of materials.
• Precision Class 8g thread fit ensures consistent, reliable engagement with mating nuts for secure, vibration-resistant assemblies.
• Rounded carriage head with wide bearing surface distributes clamping force effectively, reducing the risk of surface damage and improving aesthetic integration.
• Compliance with DIN 603 and ISO 8678 standards guarantees dimensional accuracy, interchangeability, and conformance to internationally recognized engineering specifications.

Professional Applications & Engineering Value

This M8 carriage bolt is engineered to solve critical fastening challenges in demanding industrial settings. The 18-8 stainless steel construction offers exceptional resistance to rust and oxidation, making it ideal for outdoor equipment, marine hardware, and food processing machinery where moisture is a concern. The square neck is a key feature that bites into the mounting surface, providing a reliable anti-rotation lock that eliminates the need for a separate washer or tool to hold the bolt head during tightening. This is particularly valuable in wood-to-metal connections, conveyor systems, and structural frameworks where vibration loosening is a common failure point. The fully threaded coarse pitch design ensures quick and deep engagement, even in softer materials, providing a secure and durable fastening solution that reduces assembly time and maintenance needs.
