Monel 400 Hexagon Lock Nut with Vespel Insert

Our Monel 400 hexagon lock nut is machined from Monel 400 (UNS N04400) nickel-copper alloy and fitted with a Vespel polyimide insert. The Vespel insert keeps the prevailing-torque locking action working at higher temperatures, while the Monel 400 body delivers outstanding resistance to seawater, hydrofluoric acid, sulfuric acid and alkali. Together they are built for higher temperature or corrosive applications.

Key Selling Points

Vespel Insert — polyimide non-metallic insert for reliable prevailing-torque locking.
Higher Temperature — Vespel insert keeps locking up to 260°C continuous, far above standard nylon-insert nuts.
Corrosive Applications — Monel 400 body resists seawater, acids and alkali.
Reusable Locking — vibration-resistant, can be reused several times with consistent torque.
Non-Magnetic — suitable for sensitive instrumentation.
