Key Features & Benefits at a Glance
- Exceptional tensile strength of 120,000 psi ensures reliable performance in demanding applications and prevents premature failure.
- Superior corrosion resistance from the zinc-flake coating extends service life, reducing replacement frequency and maintenance costs.
- High hardness rating (Rockwell C25) provides excellent wear resistance and durability against abrasion in industrial environments.
- Square neck design prevents rotation during installation, ensuring secure fastening and simplifying assembly processes.
- Coarse UNC threading offers faster installation and superior holding power in wood, metal, and other common materials.
- Full threading along the entire 3" length allows for maximum adjustability and grip in a wide range of material thicknesses.
- Compliance with major standards (ASME B18.5, SAE J429) guarantees consistent quality, interchangeability, and engineering reliability.
Professional Applications & Engineering Value
This Grade 5 carriage bolt is engineered for heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The zinc-flake coated steel construction provides a robust barrier against rust and chemical exposure, making it ideal for outdoor equipment, agricultural machinery, and construction frameworks. The square neck securely locks into materials to prevent spinning during torque application, while the coarse UNC thread ensures quick, deep engagement in wood and soft metals. Its fully threaded design and 120,000 psi tensile strength deliver consistent clamping force, solving common issues of joint loosening and material fatigue in dynamic load environments.
Specification Summary & Compliance
This carriage bolt features a 7/16"-14 UNC thread with Class 2A fit tolerance for consistent assembly. It is manufactured to meet ASME B18.5 and SAE J429 specifications, ensuring dimensional accuracy and mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its safety for use in regulated markets.
