The Problem:
Improper torqueing, poor mating surfaces, vibration, temperature changes create vehicle loose wheel nuts.
The Solution:
SafetyTrim Loose Wheel Nut Monitoring System
Detects and Locks Loose Wheel Nuts.
How it Works:
SafetyTrim nut pot covers with an attached extended indicator arm move freely in a fixed circular wheel trim plate.
Individual alternate split taper nut splines (some having tapers, others straight), on installation, allow each wheel nut to be fully covered and held in any position.
Each nut pot cover moves freely inside the wheel trim fixture or fixing plate. As an individual wheel nut moves (loosens) its indicator arm moves into an observation window in the trim plate indicating a loose nut situation.
The edge of the circular wheel trim has a retaining lip or shoulders which "locks" or stops additional indicator arm movement arresting further nut loosening action.
The Only Loose Wheel Nut Indicator That Prevents Further De-Torqueing
Where Used:
