Product Description
Hardy 1403970 Marquis LWT Trout Regulator Button Screw
The Hardy 1403970 Marquis LWT Trout Regulator Button Screw is a precision-machined fastener designed to secure the regulator adjustment knob to the internal drag mechanism. This screw is a critical link in the "click-and-pawl" system of the Hardy Marquis series, ensuring that the external regulator button remains firmly attached to the internal cam while allowing for smooth, rotational adjustment of the drag tension.
Manufactured in Alnwick, England, this screw features the exact thread pitch and head geometry required for the modern Marquis LWT (Lightweight) series. Because the regulator button is frequently handled for on-the-fly adjustments, this screw is engineered to resist loosening from vibration while maintaining the refined tactile feel that Hardy anglers expect.

Maintenance & Lubrication
The regulator button screw is a common point for "hidden" corrosion and grit accumulation. To ensure your drag adjustment remains smooth and to prevent the screw from seizing over time, we recommend using Deuthlon high-performance lubricants:
-
Anti-Seize Protection: Apply a small amount of Deuthlon Power Grease to the threads of the 1403970 screw before installation. This acts as a waterproof barrier and ensures the screw can be easily removed for future maintenance or deep cleaning.
-
Smooth Operation: A drop of Deuthlon Reel Gear Oil on the underside of the screw head will reduce friction against the regulator button, resulting in a crisper, more effortless adjustment feel.
