Professional Applications & Engineering Value

This M5 carriage bolt is engineered to address critical fastening challenges in industrial applications where vibration resistance and long-term reliability are paramount. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for outdoor machinery, agricultural equipment, and structural assemblies exposed to moisture. The square neck design securely locks into the mating material, eliminating spin during nut tightening and preventing loosening under dynamic loads. With a fully threaded metric coarse thread (M5x0.8mm), it ensures maximum thread engagement and ease of installation in wood, metal, or composite materials. The combination of 70,000 psi tensile strength and Rockwell B55 hardness provides a durable, high-integrity fastening solution for heavy-duty frames, conveyor systems, and transportation equipment.

Specification Summary & Compliance

This carriage bolt features a metric M5x0.8mm coarse thread with a Class 8g thread fit per ISO standards, ensuring dimensional accuracy and reliable performance. It is manufactured in compliance with the DIN 603 specification for carriage bolts. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it is free from hazardous substances and safe for use in regulated industries.
