S-98930A213 M10 x 25 mm ISO 8678 Carriage Bolts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with zinc yellow-chromate plating, extending service life in harsh industrial environments
• High tensile strength of 110,000 PSI (Class 8.8) ensures reliable performance under heavy loads and vibration
• Secure anti-rotation locking thanks to the integrated square neck design that prevents spinning during installation
• Superior thread engagement with coarse M10x1.5 threading and Class 6g fit for quick assembly and consistent clamping force
• Optimized durability with Rockwell C22 hardness providing excellent wear resistance and deformation prevention
• Wide-rounded head design offers larger bearing surface for enhanced load distribution and reduced surface damage
• Full compliance with ISO 8678 guarantees dimensional accuracy and interchangeability in global engineering applications

Professional Applications & Engineering Value

These M10 carriage bolts deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides a robust barrier against corrosion in outdoor equipment, agricultural machinery, and construction frameworks. The square neck securely locks into assembled materials, eliminating rotational slippage during torque application - a common failure point in dynamic load environments. With fully threaded coarse pitch design, installers achieve faster assembly cycles while maintaining consistent preload in wood-to-metal joints, trailer assemblies, and structural steel connections. The Class 8.8 strength rating ensures these metric fasteners withstand extreme tension and shear forces, making them ideal for heavy-duty applications requiring predictable mechanical performance and long-term reliability.

Specification Summary & Compliance

Manufactured to ISO 8678 specifications with Class 6g thread tolerance for precise fitment. Features M10x1.5 coarse threads with right-hand orientation and 25mm length with 4mm square neck (10.58mm width). The zinc yellow-chromate plating meets RoHS and REACH environmental compliance standards while providing corrosion protection. Class 8.8 mechanical properties guarantee minimum 110,000 PSI tensile strength and Rockwell C22 hardness, ensuring consistent performance across industrial applications.
