Product Description
Hardy 1329260 HREUN005SP32 Main Shaft Lock Nut
The Hardy 1329260 Main Shaft Lock Nut (Hardy Style No: HREUN005SP32) is a critical structural fastener used in the modern Hardy Ultralite series. This nut is responsible for securing the main spindle (the shaft upon which the spool rotates) to the reel’s frame or "back plate." Because the spindle must withstand significant axial torque and vibration while fighting fish, this lock nut is engineered with precise threads and a high-strength profile to ensure the reel’s foundation remains rock-solid.
In modern Hardy architecture—especially the Ultralite CC (Clicker) and certain DD (Disc Drag) models—this part ensures that the spindle does not back out or develop lateral play, which would otherwise lead to spool misalignment or catastrophic mechanical failure.

Models This Part Fits
The 1329260 lock nut is a core component for Hardy's precision "Large Arbor" clicker and disc drag reels:
-
Hardy Ultralite CC (Clicker) Series: 1000, 2000, 3000, 4000
-
Hardy Ultralite DD Series: (Verified fit for specific mid-size frame configurations)
-
Hardy Ultralite CA DD: (Compatible with specific spindle assemblies)
Technical Note: This is the primary nut that keeps the "spine" of your reel attached to the frame. If you notice your spool has developed a "clunk" or if the spindle tip appears to be moving, check the torque on this lock nut immediately. You can find the exact torque orientation and assembly sequence for your reel at www.reelschematic.com.
Key Features
-
Vibration Resistance: Designed with tight thread tolerances to prevent loosening under the rhythmic vibration of the clicker or drag systems.
-
Corrosion-Proof Construction: Built to withstand constant exposure to wet fly lines and humid storage without seizing.
-
Low-Profile Design: Engineered to stay flush with the internal frame housing, ensuring it does not interfere with the spool's rotation or the drag stack.
-
OEM Integrity: Unlike standard nuts, this part matches the specific British thread standards used in Alnwick-designed reels, preventing damage to the spindle's threads.
Maintenance & Installation
Because this nut is the final point of security for the spindle, it should be checked during your annual deep clean. We recommend using Deuthlon high-performance lubricants during service:
-
Seize Prevention: Apply a small amount of Deuthlon Power Grease to the spindle threads before threading on the 1329260 nut. This acts as a waterproof barrier and anti-seize agent, ensuring that the nut can be removed for future maintenance without stripping the spindle.
-
Environmental Seal: Once the nut is tightened, a light wipe with Deuthlon Reel Gear Oil over the exposed metal will help shed water and prevent grit from accumulating in the thread gap.
