Professional Applications & Engineering Value
This heavy-duty M12 carriage bolt is engineered to solve critical challenges in construction, machinery assembly, and structural frameworks. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor, marine, or chemically exposed environments. The defining square neck under the rounded carriage head is a key engineering feature, biting into the mounting material to prevent rotation when the nut is tightened. This eliminates the need for secondary locking mechanisms, speeding up assembly and enhancing joint integrity. The fully threaded coarse pitch design offers superior pull-out resistance in wood, metal, and composite materials, ensuring a secure, long-lasting fastening solution for demanding professional applications.
Specification Summary & Compliance
This metric carriage bolt features an M12 thread size with a 1.75mm coarse pitch and a Class 8g thread fit, ensuring dimensional accuracy and compatibility with standard nuts. It is manufactured in compliance with the DIN 603 standard and meets critical regulatory requirements, including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free from hazardous substances and safe for use in various markets.
