Professional Applications & Engineering Value
This heavy-duty carriage bolt is engineered to solve critical fastening challenges in construction, machinery assembly, and structural applications. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor, marine, and high-moisture environments. The square neck design is a key engineering feature that prevents the bolt from rotating during installation, ensuring a secure and permanent fit in wood, metal, or composite materials. Combined with the coarse UNC thread and fully threaded shank, it delivers superior pull-out resistance and vibration-proof performance. This bolt is ideal for demanding industrial applications where reliability, durability, and compliance with strict standards are paramount.
Specification Summary & Compliance
This carriage bolt features a 1/2"-13 UNC coarse thread with a Class 2A thread fit for precise dimensional accuracy and reliable nut engagement. It is manufactured in compliance with the ASME B18.5 standard, ensuring consistent quality and interchangeability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for hazardous substances.
