Sirius Nyloc Lock Nuts Bright Zinc Plated

The Sirius Nyloc Lock Nuts Bright Zinc Plated in M20 are heavy-duty self-locking fasteners designed for large-scale structural, civil engineering and industrial applications. The M20 size provides substantial clamping force and is commonly used in steel frame construction, heavy plant and machinery, bridge work, and other applications where large-diameter, high-integrity fixings are specified.

The nylon locking collar maintains a firm grip on the bolt threads to resist loosening under significant vibration and dynamic loads, while the bright zinc plated finish offers reliable corrosion resistance for both indoor and outdoor environments.

Requires appropriately sized spanners or sockets and is suited to professional engineers, structural contractors and specialist fabricators.
