Ay-Yıldız Engineering Nuts are essential components used in Rock Bolt systems to create a secure connection between the anchor bar and the bearing plate. By allowing the bolt to reach the correct tension level, the nut enhances the overall load-carrying capacity of the anchorage system. Manufactured from high-strength steel, these nuts deliver long-lasting durability and consistent performance even under demanding geological conditions.
During rock bolt installation, the nut ensures proper load transfer and contributes to system stability throughout drilling and grouting operations. With various diameter and length options available, Ay-Yıldız Engineering Nuts are suitable for a wide range of tunneling, mining and construction applications. They maintain system integrity in deep anchorage setups and provide reliable tightening where high performance is required.
