The Locking Bolt (Code: 847490) is a high-performance OEM spare part exclusively engineered for the Metso Nordberg HP4 Cone Crusher, manufactured by the reputable brand ONA. Designed to meet the rigorous demands of industrial crushing operations, this bolt is a critical component that ensures the stability, precision, and longevity of the HP4 cone crusher. Unlike generic alternatives, the ONA Locking Bolt undergoes strict precision engineering to achieve a perfect fit with the HP4 model, eliminating the risks of component loosening or unexpected failure during heavy-load crushing processes. As a core cone crusher spare part, it plays an indispensable role in maintaining consistent equipment performance, minimizing unplanned downtime, and reducing long-term maintenance costs for mining, quarrying, and aggregate processing enterprises. Whether for routine maintenance or emergency replacement, this locking bolt stands out as a reliable choice for businesses relying on Metso Nordberg crushing equipment.

The Locking Bolt is crafted from top-grade materials that are carefully selected to withstand the harsh operating conditions of cone crushers. These materials are chosen for their superior tensile strength, wear resistance, and corrosion resistance, ensuring the bolt can endure high impact forces, constant vibration, and abrasive material contact common in crushing environments.
Before entering the production process, all raw materials undergo strict quality inspections to verify their mechanical properties and structural integrity. This meticulous material screening process guarantees that every bolt meets the highest industry standards, laying a solid foundation for the product’s durability and long service life. The use of such premium materials also ensures that the bolt does not deform or break easily, even under prolonged high-load operations.
The adoption of top-grade materials is the cornerstone of the Locking Bolt’s outstanding performance. These materials enhance the bolt’s resistance to wear, fatigue, and corrosion, significantly reducing the frequency of replacements. For businesses, this translates to lower operational costs and fewer interruptions to production schedules, making the bolt a cost-effective investment in the long run.
Every ONA Locking Bolt is manufactured with advanced precision engineering techniques, ensuring a seamless fit with the Metso Nordberg HP4 Cone Crusher. The strict control of dimensional accuracy eliminates gaps between the bolt and associated components, preventing equipment malfunctions caused by ill-fitting parts. This precision also ensures stable performance even under extreme crushing conditions, maximizing the efficiency of the HP4 cone crusher.
ONA offers flexible OEM/ODM services for the Locking Bolt, catering to the unique needs of different customers. Clients can customize elements such as branding, labeling, painting colors, and packaging, allowing the product to align with their corporate identity or specific application requirements. This customization option makes the bolt a versatile solution for diverse industrial scenarios.
From raw material procurement to the final product delivery, the Locking Bolt undergoes rigorous quality control checks at every stage of production. Each bolt is inspected for dimensional accuracy, material consistency, and mechanical performance, ensuring that only products meeting the highest standards reach customers. This commitment to quality guarantees reliable performance in real-world crushing operations, minimizing the risk of equipment breakdowns.
