Mining Hex Nut | 4140 Alloy Steel | Grade 10″

High-Strength Mine Hexagon Nuts for Heavy-Duty Industrial Applications

Our Mine Hexagon Nuts are precision-engineered fasteners designed to withstand extreme conditions in mining, construction, and heavy machinery applications. Manufactured from high-grade alloy steel with hot-dip galvanized or zinc-plated finishes, these nuts offer superior corrosion resistance and durability in harsh environments. Available in metric and imperial sizes (M12 to M64, 1/2″ to 2-1/2″), our hex nuts meet international standards including DIN 934, ISO 4032, and ASTM A563 specifications.

The heavy-duty design features a robust hexagonal shape for optimal wrench grip and torque transmission, ensuring secure fastening even under high vibration loads. Our nuts undergo rigorous quality control, including hardness testing (HRC 22-34) and dimensional verification, to guarantee consistent performance in critical applications. Special anti-loosening variants with nylon inserts or metal locking features are available for enhanced safety in dynamic load conditions.

Key advantages include:

• Exceptional durability with tensile strengths up to 1,200 MPa
• Corrosion-resistant coatings for extended service life in wet/abrasive environments
• Precision threading for perfect compatibility with high-strength bolts
• Wide temperature tolerance (-40°C to +300°C) for extreme conditions
• Full traceability with material certifications and batch testing reports

Common applications include: mining equipment assembly, conveyor systems, crusher machinery, and structural connections where vibration resistance is critical. We offer both standard configurations and custom solutions with special thread pitches, chamfer designs, or marking requirements.
