WHEEL NUT INDICATORS

When fitted on the wheel nut it will indicate a loosening by
movement of the pointer. Suitable for wheels with exposed
nuts. To suit 4x4, light commercial and mine specification
applications.

The Wheel Nut Indicator is fixed to the wheel nut by gripping the six
corners of the hexagon. When the wheel is being fitted out the Indicator
pointers should be aligned and set in a recognisable pattern. Should a
wheel nut loosen off, the Indicator has no option but to move with the nut
and so break the pattern, thus indicating the wheel nut has begun to rotate
and therefore loosen.

be cleaned using any of the available vehicle cleaning agents, detergent
solutions or paraffin’s.

The Indicators are not attacked by road salts or petrochemicals. The
pointer being large, it is highly visible even when coated with road or
operational grime.

Advantages:
• Reduces the risk of wheel detachment accidents, which protects the
Safe - pattern maintained Unsafe - pattern broken public and helps prevent property and load damage.
• Vehicle wheel safety checks are made simple by making them visual.
• Quickly identifies a hot wheel condition, possibly caused by bearing
failure or brake drag.
• Assists in fleet maintenance and safety.
• Decreased equipment down time and operational costs.
• Demonstrates a fleet operator’s commitment towards vehicle safety.
• Facilitates easy roadside inspections.
• Easy to install.

Application:
1. Torque wheel nuts to required specifications.
2. Ensure correct Indicator size by measuring nut from flat to flat.
