Professional Applications & Engineering Value
This heavy-duty carriage bolt is engineered to solve critical challenges in construction, machinery, and structural applications. The 18-8 Stainless Steel construction provides inherent resistance to rust and corrosion, making it ideal for outdoor equipment, marine hardware, and facilities exposed to moisture or chemicals. The integral square neck is a key engineering feature, locking securely into the mounting material to prevent rotation when torque is applied—eliminating the need for a second wrench and speeding up assembly. Combined with its coarse 5/16"-18 UNC thread, this bolt ensures robust, vibration-resistant connections in wood-to-metal and structural timber frameworks, delivering long-term reliability and reduced maintenance.
Specification Summary & Compliance
This carriage bolt features a 5/16"-18 UNC coarse thread with a Class 2A thread fit for standard tolerance and easy assembly. It is manufactured in compliance with the ASME B18.5 standard, ensuring dimensional accuracy and interchangeability. The product is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming it is free of hazardous substances and suitable for regulated markets.
