Product Description
Shimano 10J20 Star Drag Click Plate (BNT5047) | 12CT200D Replacement
The Shimano 10J20 Star Drag Click Plate (often abbreviated as S/D/C Plate) is a precision-engineered internal component that sits within the star drag assembly of high-performance baitcasting reels. This part is responsible for providing the mechanical interface between the star drag wheel and the clicker mechanism, creating the audible "click" sound and tactile feedback as you adjust your drag tension.
Made from hardened, corrosion-resistant alloy, the 10J20 is designed to withstand the friction of constant adjustment while ensuring your drag settings remain stable during high-pressure fights. If your star drag has become silent or feels loose when clicking through settings, this plate is likely worn and requires replacement.

Maintenance & Lubrication Recommendation
The click plate is a high-contact area that benefits greatly from correct lubrication to prevent metal-on-metal wear. We recommend Deuthlon Lubricants for this service:
-
For the Clicker Face: Apply a light film of Deuthlon Reel Gear Grease. Its high-tack formula ensures the clicker sound remains crisp while providing a barrier against moisture and salt.
-
For the Drive Shaft Interface: Use a drop of Deuthlon Power Cast Oil on the shaft before sliding the plate into position to ensure smooth movement and prevent seizing.
Why Choose Genuine Shimano 10J20?
The star drag system relies on microscopic tolerances to provide consistent "micro-click" adjustments. Using the genuine 10J20 (BNT5047) ensures:
-
Tactile Precision: Restores the factory "click" feel.
-
Drag Stability: Prevents the star drag wheel from "walking" or loosening under load.
-
Perfect Fit: Ensures the plate sits flush against the drag spring washers and the star drag nut.
