10KK2 CAST CONTROL CAP (BNT2476)

Product Description

Shimano 10KK2 Cast Control Cap (BNT2476) | Spool Tension Knob

The Shimano 10KK2 Cast Control Cap (BNT2476) is a genuine OEM replacement part designed for the precision adjustment of spool tension on Shimano’s flagship round-profile baitcasting reels. This cap, often referred to as the spool tension knob, is the primary interface for setting the "mechanical brake," allowing anglers to fine-tune the spool's rotation speed to match lure weight and wind conditions.

Constructed from a high-grade aluminum alloy with a protective silver anodized finish, the 10KK2 features an ergonomic knurled texture for effortless micro-adjustments in wet or cold conditions. Replacing a lost or damaged cap is essential for maintaining casting control and preventing the dreaded "professional overrun" (backlash).

Maintenance & Lubrication Recommendation

The internal threads and the contact point where the spool shaft meets the internal spacer require proper lubrication to ensure smooth adjustment and prevent seizing. We recommend Deuthlon Lubricants:

• For the Threads: Apply a light film of Deuthlon Reel Gear Grease. This high-tack grease provides a waterproof barrier that prevents the aluminum cap from seizing to the side plate threads, especially in brackish or saltwater environments.

• For the Internal Shim/Spool Tip: Use a single drop of Deuthlon Power Cast Oil. This ultra-low friction oil ensures that the spool shaft rotates freely against the internal friction shim, maximizing casting distance even when tension is applied.

Why Choose Genuine Shimano 10KK2 Parts?

Using the original BNT2476 (10KK2) ensures that the thread pitch and depth match your reel's frame perfectly.

• Avoid Cross-Threading: Generic or "universal" caps often have slight thread variances that can permanently damage your reel's side plate.

• Corrosion Protection: The specialized anodized finish is designed to resist the "tea-staining" and oxidation common with aftermarket hardware.

• Precision Tension: Maintains the factory-calibrated pressure required to stabilize the spool during high-speed rotation.
