Key Features & Benefits at a Glance
- Superior anti-rotation performance with a square neck design that prevents spinning during installation and under vibration, ensuring a secure, permanent fit.
- High tensile strength of 110,000 psi from the Class 8.8 steel construction, providing reliable load-bearing capacity for demanding structural and industrial applications.
- Enhanced durability and wear resistance due to a Rockwell C22 hardness, extending the bolt's service life in high-stress environments.
- Optimized for quick and easy installation with a fully threaded, coarse M12 x 1.75 mm right-hand thread that reduces assembly time and prevents cross-threading.
- Broad compatibility and secure fit ensured by the Class 6g thread fit and compliance with ASME B18.5 and ISO 8678 standards for consistent performance.
- Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental and safety regulations.
- Versatile rounded head profile with a wide bearing surface that minimizes surface damage and provides a clean, finished appearance.
Professional Applications & Engineering Value
This M12 carriage bolt is engineered to solve critical fastening challenges in industrial and construction settings where vibration loosening and high shear forces are common. The integral square neck is a key engineering feature, locking securely into the mounting material to provide unmatched anti-rotation capability. This eliminates the need for supplementary locking washers or tools, streamlining assembly in applications like heavy machinery, structural steel framing, and conveyor systems. Manufactured from Class 8.8 steel with a coarse metric thread, it offers a robust combination of high tensile strength and ease of installation, making it a reliable, long-lasting fastening solution that reduces maintenance and downtime.
Specification Summary & Compliance
This bolt features a metric M12 x 1.75 mm coarse thread with a Class 6g tolerance for precise fit. It is manufactured to meet the dimensional and mechanical specifications of ASME B18.5 and ISO 8678. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances for safe use in various global markets.
