Professional Applications & Engineering Value

This 7/16"-14 UNC Carriage Bolt is engineered to solve critical fastening challenges in demanding industrial applications. The combination of 18-8 Stainless Steel provides excellent resistance to rust and corrosion, making it suitable for construction, agricultural machinery, and marine environments where exposure to moisture is a concern. The square neck is a key feature that bites into the mounting material, effectively preventing rotation and eliminating the need for a separate washer or tool to hold the bolt head during nut tightening. This design, paired with a coarse thread and full threading, ensures a secure, vibration-resistant connection that maintains integrity under stress, reducing maintenance needs and improving the longevity of the assembled structure.

Specification Summary & Compliance

This bolt features a 7/16"-14 UNC thread with a Class 2A fit for standard clearance and ease of assembly. It is manufactured to meet the dimensional requirements of ASME B18.5. The product is also confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it is free of hazardous substances and safe for use in regulated markets.
