Product Description
Shimano 10QUC Handle Bolt Plate (TGT0973 & TT 0002A)
The Shimano 10QUC Handle Bolt Plate is a critical external safety component designed for Shimano’s most powerful offshore trolling reels. This plate acts as a locking retainer for the handle bolt, ensuring that the heavy-duty handle remains securely attached to the drive shaft even under the immense vibration and torque generated when fighting giant game fish like tuna and marlin.
The 10QUC is the current global part number that consolidates and replaces legacy specifications, including TGT0973 and TT 0002A. If your reel schematic lists any of these older numbers, the 10QUC is the official factory-direct replacement.

Technical Tip: This plate is secured by two small Handle Bolt Plate Screws (TGT0003). Because it is located at the very end of the handle assembly, it is highly susceptible to salt spray. If the plate is missing or cracked, the handle bolt can slowly loosen, which may lead to the handle falling off mid-fight—a catastrophic failure in big-game fishing.
Maintenance & Installation Recommendation
The area behind the handle bolt plate is a common "salt trap." To maintain the integrity of your handle assembly, we recommend Deuthlon Lubricants:
-
For the Mounting Screws: Apply a tiny amount of Deuthlon Reel Gear Grease to the threads of the two small locking screws. This prevents the stainless steel screws from "cold-welding" to the aluminum handle, allowing for easy removal during your next service.
-
Under the Plate: Wipe a thin film of grease on the underside of the 10QUC plate before installation. This creates a hydrophobic barrier that prevents salt crystals from forming in the gaps, which can cause the plate to "pit" or corrode over time.
Why Choose Genuine Shimano 10QUC?
-
Precision Indexing: Machined to fit the hexagonal head of the handle bolt with zero "slop," ensuring it can't rotate even a fraction of a degree.
-
Offshore Durability: Features a specialized anti-corrosive coating specifically tested for the high-salinity environments encountered in blue-water trolling.
-
Safety Redundancy: Provides the final layer of security for the reel's primary power transfer point, protecting both the gear system and the angler.
