Product Description
Shimano 10P5T Handle Screw Cap (RD 1442) | Protective Side Cover
The Shimano 10P5T Handle Screw Cap (RD 1442) is a genuine OEM external component for Shimano spinning reels. This cap threads onto the side of the reel housing opposite the handle, serving two primary functions: it protects the internal drive gear and handle threads from dust, salt, and debris, and it provides a finished aesthetic while helping to keep the handle assembly secure.
Precision-molded from high-impact, UV-stabilized polymer, the 10P5T is the current global part number that consolidates and replaces the older RD 1442 and BR 0313 specifications. It is designed to be easily removed by hand, allowing for quick handle side swaps or basic maintenance.

Technical Tip: This cap is often the first part lost during transport or when switching the handle from right-hand to left-hand retrieve. If the cap is missing, moisture can easily enter the main gear bearing, leading to premature gear "grind." For the exact orientation, consult the PDF schematics at www.reelschematic.com.
Maintenance & Protection Recommendation
Because the handle screw cap is frequently handled and exposed to the elements, the threads can become caked with salt or sand. To ensure a lifetime of easy removal and a perfect seal, we recommend Deuthlon Lubricants:
-
For the Threads: Apply a light film of Deuthlon Reel Gear Grease to the internal threads of the cap. This high-tack, waterproof grease prevents "cold-welding" (seizing) and blocks moisture from entering the gearbox.
-
For the Internal Bearing: While the cap is removed, add a single drop of Deuthlon Power Cast Oil to the drive gear bearing visible inside the housing to maintain ultra-smooth rotation.
Why Choose Genuine Shimano 10P5T?
-
Factory Thread Match: Eliminates the risk of cross-threading the drive gear or side plate.
-
UV Stability: Shimano’s specific polymer blend won't become brittle or "chalky" after prolonged exposure to the sun.
-
Seamless Fit: Provides a flush seat against the reel body, preventing line snags during the cast or retrieve.
