Sargent 13-0180 Mortise Cylinder Nut | For ET Trim & Key Switches

The Sargent 13-0180 is a genuine OEM replacement mortise nut designed to provide a secure, vibration-resistant mount for threaded mortise cylinders. As a fundamental component in Sargent’s architectural hardware ecosystem, this nut ensures that the cylinder remains perfectly aligned and stationary, preventing the lock from spinning or backing out during key rotation. Whether used in high-traffic exit device trim or sensitive electronic key switches, the 13-0180 is built to factory specifications for a precision fit.

Multi-Application Versatility

• 700 Series ET Trim: The primary locking nut used to secure cylinders within Sargent’s heavy-duty Extra Thick (ET) outside lever and pull trim.
• Cylinder Dogging Assemblies: Essential for anchoring the dogging cylinder in exit devices, allowing the pushpad to be locked in the retracted position.
• Access Panels & Key Switches: Provides a low-profile, high-strength mounting solution for cylinders used in electrical key switches and security access panels.
• Hardened Thread Design: Manufactured to match standard mortise cylinder threading, ensuring a smooth install without the risk of cross-threading.
• Corrosion Resistant: Built from high-quality materials to withstand the environment and frequent use in commercial and institutional settings.

The Sargent 13-0180 is a "must-have" spare part for any commercial locksmith or facility manager. Because these nuts are thin by design to fit into tight housings, they can occasionally become rounded or stripped if over-tightened with improper tools. For a secure installation, ensure the cylinder is threaded through the trim and the nut is tightened flush against the internal mounting surface.

Installation Note: In high-vibration applications, such as on a 700 Series ET trim, the stability of the entire trim assembly is just as important as the cylinder nut. Always verify that the ET trim is anchored to the door using high-strength thru bolts. If the trim is loose on the door, it can cause the cylinder to vibrate against the 13-0180 nut, eventually loosening the assembly and leading to mechanical failure.
