• Optimized coarse threading (M8 x 1.25mm) allows for faster installation and better performance in soft materials
• Precision manufacturing with Class 6g thread fit ensures consistent quality and reliable mating with nuts
• Full threading capability provides maximum flexibility for various material thicknesses and assembly requirements
• ISO 8678 compliance guarantees international quality standards and interchangeability across global projects

Professional Applications & Engineering Value

These M8 carriage bolts with Class 8.8 strength rating and zinc yellow-chromate plating deliver exceptional value in demanding industrial applications. The square neck design effectively prevents rotation during installation, eliminating the need for additional locking mechanisms in wood-to-metal and structural connections. The coarse metric threading (1.25mm pitch) provides superior holding power in softer materials while resisting vibration-induced loosening. With Rockwell C22 hardness and 110,000 PSI tensile strength, these fasteners maintain integrity under extreme mechanical stress, making them ideal for construction equipment, agricultural machinery, transportation systems, and heavy-duty framework assemblies where reliability cannot be compromised.

Specification Summary & Compliance

This metric carriage bolt features M8 x 1.25mm coarse threading with Class 6g tolerance for precise fitment. Manufactured to ISO 8678 specifications, it ensures international standardization and compatibility. The Class 8.8 strength rating (equivalent to 110,000 PSI tensile strength) and Rockwell C22 hardness provide verified mechanical performance. The zinc yellow-chromate plating offers enhanced corrosion protection while maintaining environmental compliance with RoHS and REACH regulations. The 35mm length with full threading and square neck design delivers consistent, reliable fastening performance across industrial applications.
