In HC95 Hydraulic Rock Drill (or Hydraulic Drifter) systems, the Stud 101044460 (connecting shaft) is a “structural linkage core”—it’s installed between fixed and movable components (e.g., the drill’s housing and bracket, or cover and cylinder) to maintain component alignment and transmit stable loads. During high-vibration drilling (up to 1600 bpm), this shaft endures constant shear force and mechanical impact; a faulty shaft can cause component misalignment, noisy operation, or even sudden disconnection—posing safety risks to operators and halting mining work.

1. High durability: Made of heat-treated alloy steel (tensile strength ≥ 850 MPa), it resists bending and thread damage even under long-term heavy use.
2. Precision fit: The shaft diameter and thread pitch are machined to ±0.003mm tolerance, ensuring a tight, gap-free fit with HC95’s components—no loosening that causes wear.
3. Corrosion resistance: The surface features anti-rust zinc plating, protecting it from damp underground mines or dusty surface quarries.
