Details
1. Mining Nut Product Overview
Mining nuts are high-strength fasteners specifically designed for heavy-load bolted connections in mining, tunneling, and other demanding industrial applications. Also known as high-strength hex nuts, bolting nuts, or threaded nuts for rock bolts, these products ensure reliable mechanical performance, excellent fatigue resistance, and long-term durability.
2.Key Benefits of Mining Nuts
- High Strength Performance: Designed to withstand heavy-load and cyclic forces.
- Reliable Mechanical Connection: Perfectly mates with bolts, rock bolts, and threaded rods for secure fastening.
- Excellent Fatigue Resistance: Suitable for long-term and dynamic load applications.
- Customizable Sizes & Threads: Diameters, lengths, and thread types can be tailored per project.
- Corrosion-Resistant Coatings: Optional surface treatments for harsh mining environments.
- Easy Installation: Standard hex or specialized shapes for efficient torque application.

Notes:
1.Thread Size: Refers to the diameter and pitch of the nut’s internal thread.
2.Material: Common materials for mining nuts include Q235, 45# steel, 35# steel, 40Cr, 35CrMoA, etc.
3.Strength Grade: Strength grades such as Grade 8.8, Grade 10.9, Grade 12.9 indicate the nut’s load-bearing capacity and tensile strength. The higher the grade, the stronger the nut.
4.Surface Treatment: Surface treatments commonly used include zinc plating, hot-dip galvanizing, black oxide, passivation, etc.
The specifications of mining nuts can vary depending on the specific application and standards. When purchasing, it is important to consider the environmental factors (such as high temperature, humidity, etc.) that may affect the material and durability of the nuts.
