Strict Quality
Control

Standard for low/thin-type prevailing-torque hexagon lock nuts.

General-purpose corrosion resistance, suitable for indoor and outdoor fixings.

Creates a prevailing-torque lock that resists loosening from vibration, without needing a separate lock washer.

Without damaging the bolt thread, unlike a fully deformed all-metal lock nut.

Throughout the range.

Hex across-flats size matches a standard hexagon nut of the same thread diameter.

Lasting deformation typically starting above ~130-140°C.

Covering the majority of general engineering and construction fixings.
