Professional Applications & Engineering Value

These M16 carriage bolts deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides superior corrosion protection for outdoor equipment, agricultural machinery, and construction applications exposed to environmental elements. The square neck design fundamentally solves rotational slippage issues in wood-to-metal and structural steel connections, eliminating the need for additional locking mechanisms. With fully threaded metric coarse threading and Class 8.8 strength grade, these fasteners maintain clamping force in high-vibration environments while supporting heavy loads up to 120,000 psi tensile strength. The combination of Rockwell C22 hardness and precise Class 6h thread fit ensures consistent performance in assembly line operations and field maintenance scenarios.

Specification Summary & Compliance

This metric carriage bolt features precise M16 x 2mm coarse threading with Class 6h thread fit tolerance according to ISO standards. The fastener maintains dimensional accuracy with a 60mm length, 35mm head diameter, and 16.7mm square neck width. Manufactured to meet ASME B18.5 and ISO 8678 specifications, ensuring interchangeability and performance reliability. The zinc yellow-chromate plating on steel substrate provides RoHS and REACH compliant corrosion protection while maintaining the Class 8.8 mechanical properties with verified 120,000 psi tensile strength and Rockwell C22 hardness ratings.
