With a comprehensive product range, Tianlong dome mining bolt nut offer thread sizes from M16 to M50, suitable for diverse applications:

M16-M24: Ideal for precise connections in coal mine ventilation pipeline fasteners and monitoring instrument bracket fixing.

M27-M36: Commonly used for roller connections in belt conveyors, hydraulic support pipeline fixing, and other medium-duty applications.

M39-M50: Designed for core components of large mining equipment, such as chain connections in scraper conveyors and load-bearing structure fixing in mine hoists.

mining bolt nut are available in strength grades 4.8, 8.8, and 10.9

Grade 4.8: Suited for low-intensity environments, including non-load-bearing component connections in auxiliary coal mine equipment, temporary support fixing, or light-load pipeline installation in ventilation and drainage systems.

Grade 8.8: Designed for medium-to-high-intensity mining scenarios, such as walking mechanism connections in shearers, roadheader cutter fixing, and conveyor belt tensioning devices.

Grade 10.9: Engineered for high-intensity, high-risk conditions, including core load-bearing components in deep mining equipment (e.g., hydraulic support main frame connections, hoist drum fixing) and heavy-duty support structures in rock burst-prone areas.

Two surface treatment options are available:

Eye-catching black finish: Enhances aesthetics while improving corrosion resistance.

Natural self-color finish: Maintains inherent strength with a raw material appearance.
