Professional Applications & Engineering Value
These M12 carriage bolts are engineered to address critical fastening challenges in industrial settings. The zinc yellow-chromate plated steel construction offers exceptional protection against rust and corrosion, making them ideal for outdoor machinery, agricultural equipment, and structural assemblies exposed to moisture. The square neck design locks securely into pre-drilled holes, eliminating rotation during nut installation and ensuring precise alignment in wood-to-metal or metal-to-metal connections. With a Class 8.8 strength grade and fully threaded metric coarse thread, these bolts provide reliable clamping force and vibration resistance in heavy-load applications such as trailer hitches, construction frameworks, and automotive components, reducing maintenance needs and improving long-term safety.
Specification Summary & Compliance
This carriage bolt features M12 x 1.75mm coarse metric threading with a Class 6h thread fit for precise engagement, and is manufactured to meet ASME B18.5 and ISO 8678 standards. The 35mm length and 26.6mm head diameter provide optimal dimensions for standard applications, while the material and plating comply with RoHS and REACH environmental regulations, ensuring safe and sustainable use across global industries.
