Sirius A2 304 Stainless Steel Nyloc Nuts

The Sirius A2 304 Stainless Steel Nyloc Nut in M18 is a heavy-duty locking fastener suited to specialist industrial, structural and mechanical engineering applications. The M18 size is less commonly stocked than standard metric sizes, making it a particularly valuable option when specific thread diameters are demanded by design specifications or replacement requirements in machinery and heavy equipment.

Manufactured from A2 304 stainless steel, this nut provides reliable corrosion resistance in both indoor and outdoor environments, including damp and exposed conditions, without the need for additional surface protection. The nylon insert locking mechanism resists loosening under vibration, shock and dynamic loading, maintaining a secure threaded connection throughout the service life of the assembly.

The standard hexagon profile is compatible with heavy-duty spanners and sockets for efficient, high-torque installation.
