Screw C011002169 is a high-strength fastening component for Hydraulic Rock Drills. It is engineered for heavy-duty mining applications. For instance, it secures parts in deep underground drilling rigs. Additionally, it performs in high-vibration open-pit mining sites.
Mining environments pose severe challenges for drill screws. First, high torque during installation risks thread stripping. Second, 38G vibration loosens fasteners during rock-breaking tasks. Third, mining slurry and humid air cause corrosion. Fourth, extreme temperature swings weaken material structure. Fifth, dust buildup clogs threads, hindering maintenance.
These issues often lead to screw failure. For example, loosened screws cause component misalignment. As a result, costly downtime and equipment damage occur. Yet, Screw C011002169 solves these pain points with robust design.
First, its 30CrNiMo8 alloy steel body delivers superior tensile strength. Moreover, the precision-rolled thread (±0.008mm) resists 1200N·m torque. This prevents stripping during high-torque installation. Consequently, service life extends by 190% vs. standard steel screws.
Second, the black oxide coating + oil-impregnated finish offers 500-hour salt spray resistance. This outperforms ordinary zinc-plated screws by 40%. Furthermore, it repels mining slurry and rust formation. This avoids thread seizing and simplifies disassembly.
Third, the thread-locking groove design enhances vibration resistance. Notably, it works with anaerobic threadlocker for permanent fastening. This prevents loosening even under 38G continuous vibration. As a result, operational safety improves significantly.
Fourth, the alloy steel material tolerates extreme temperatures (-50°C~130°C). Importantly, it maintains strength in freezing or high-heat environments. This eliminates brittleness or deformation risks in harsh mining conditions.
Fifth, the chamfered thread tip ensures smooth installation. It aligns with mating components without cross-threading. On top of that, the hexagon socket design fits standard tools. This reduces maintenance time and labor costs.
Unlike generic industrial screws, this model is purpose-built for drills. Specifically, the high-torque thread design targets stripping risks. Additionally, the anti-corrosion coating addresses mining slurry damage. These features align with real mining demands. As a result, it outperforms standard screws by 180% in service life. This cuts replacement costs and unplanned downtime.
Our manufacturing process uses CNC precision threading and heat treatment. Furthermore, it involves torque testing and corrosion resistance trials. Each unit undergoes 1200N·m torque tests and 500-hour salt spray trials. Notably, no performance degradation is allowed before shipment.
The screw operates reliably in all heavy-duty mining conditions. Moreover, the 30CrNiMo8 steel body endures 10,000-cycle vibration tests. No thread loosening occurs during this period. Additionally, the coating remains intact for 22+ months.
The drop-in installation design integrates seamlessly with drill systems. It requires only a hex socket wrench for fitting. Consequently, maintenance teams complete replacement in 5 minutes. This minimizes operational downtime.
Our quality team conducts strict ISO 9001 verification. For example, tests include torque checks, corrosion resistance trials and thread precision tests. Importantly, it complies with global mining safety standards.
It is a direct OEM replacement for top Hydraulic Rock Drill brands. Furthermore, its reliability reduces screw-related failure rates by 97%. Backed by a 12-month warranty, it lowers annual maintenance costs by 62%.
It ensures secure fastening of critical drill components during operation. Additionally, it extends the service life of drill assemblies by 88%. Overall, it delivers cost-effective, industrial-grade reliability. It minimizes downtime from screw failure. As a result, this maximizes operational efficiency and project profitability.
