Specification
High-Quality Anchor/Dome Nuts for Rock Bolts
1. Wide Product Range Coverage
The Anchor/Dome Nuts manufactured by Tianlong boast an extensive product range, covering the full size spectrum from 3/4 inch (19mm) to 2-1/2 inches (63.5mm) (corresponding to models CLHN016-1 to CLHN016-9).
They are compatible with over 80% of standard rock bolt sizes in the industry, meeting the needs of various engineering projects such as mining, tunneling, and slope support. Therefore, you do not need additional custom nuts, which helps reduce procurement and inventory costs.
2. Precise Parameter Design
The key parameters (F/D/L dimensions) of Tianlong's Anchor/Dome Nuts have undergone engineering optimization, adopting a unified model system (CLHN016 series) with extremely low dimensional tolerances.
Among them, the precise F values (35mm-90mm) and L values (40mm-120mm) endow the components with strong load-bearing capacity.
3. Safer Combination of Two Nut Types
The Anchor Nut focuses on connecting the rock bolt to the rock matrix, while the dome design of the Dome Nut can protect the end of the rock bolt from external impacts.
The combined use of these two types of nuts can simultaneously address the issues of "anchoring strength" and "impact resistance protection," reducing the failure rate of the support system.
4. High Durability
This Anchor/Dome Nuts is designed for high-pressure, vibrating, and humid rock environments. It is made of high-strength steel, featuring extremely high hardness and tensile strength, which is far superior to ordinary nuts.
Compared with products from other manufacturers, it has better wear and corrosion resistance. In high-humidity mining environments and high-dust tunnel environments, it has a long service life, which can reduce replacement frequency and lower maintenance costs.
5. Standardized Production, Compliant with Industry Norms
Tianlong's Anchor/Dome Nuts comply with international engineering standards, as well as the engineering standards of the three major markets of China, the United States, and Europe.
The product facilitates procurement for domestic and foreign engineering projects, shortens the order cycle, and has attracted the attention of engineering contractors and mining equipment suppliers from more than 100 countries and regions.
