Key Features & Benefits at a Glance
- Maximum Load-Bearing Performance: Grade 8 classification with 150,000 psi tensile strength ensures reliable operation under extreme mechanical stress.
- Superior Wear & Corrosion Resistance: Steel construction with Rockwell C33 hardness provides excellent durability in harsh environments.
- Secure Anti-Rotation Locking: Key locking neck design prevents bolt rotation during operation, maintaining consistent assembly integrity.
- Optimized Thread Engagement: UNC coarse threading with Class 2A fit offers quick installation and vibration resistance.
- Flush Mounting Capability: Standard flat head with 60° countersink angle creates smooth, snag-free surfaces.
- Industry Compliance Assurance: Meets SAE J429 specifications and environmental standards (RoHS 3, REACH) for global supply chain compatibility.
- Versatile Partial Threading: Combines threaded and unthreaded sections for ideal grip range in layered material applications.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 8 plow bolt addresses critical challenges in agricultural machinery, construction equipment, and material handling systems. The key locking neck design eliminates rotational slippage in high-vibration environments, while the steel construction with Rockwell C33 hardness withstands abrasive wear from soil, gravel, and metal-on-metal contact. The partially threaded configuration with UNC coarse spacing provides optimal clamping force distribution across multiple material thicknesses. With 150,000 psi tensile strength, this bolt maintains structural integrity in implements requiring repeated impact resistance and dynamic loading capacity.
Specification Summary & Compliance
Manufactured to SAE J429 Grade 8 standards with Class 2A thread fit for precision dimensional control. Features 5/8"-11 UNC coarse threads with right-hand direction and 1 1/2" minimum thread length. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial markets.
