Corbin Russwin 483F35-8 Spindle Adjusting Bolt

The Corbin Russwin 483F35-8 is a genuine OEM Spindle Adjusting Bolt designed exclusively for use within the 499F83-8 Spindle Assembly. This bolt is a vital internal component of the Corbin Russwin ML2000 Series Mortise Lock, serving as the adjustment mechanism that sets the depth and tension of the spindle between the interior and exterior levers. As a factory-certified Grade 1 part, the 483F35-8 ensures that the mechanical connection between your levers and the lock case remains tight, precise, and responsive.

Institutional Grade Features

• Precision ML2000 Integration: Specifically engineered to fit inside the 499F83-8 Spindle, providing the threaded adjustment required for various door thicknesses.
  
• Eliminates Lever "Play": The primary hardware solution for removing excess horizontal movement or "slop" in the lever handles, ensuring the spindle is perfectly centered within the mortise hub.
• High-Torque Durability: Manufactured from high-strength steel to resist the constant rotational stress and vibrations found in high-traffic commercial and institutional environments.
• Direct OEM Replacement: The exact factory-spec bolt used in new ML2000 installations, ensuring 100% mechanical compatibility and maintaining the lock's UL fire-rating.
• Fine-Thread Adjustment: Allows for microscopic adjustments to the lever's seating, preventing the levers from binding against the rose or falling out of alignment.
