The nut indicator is a molding made of special plastic material with an indicator edge,
which is placed on the nuts of the car wheels so that the edge always points towards the center
of the adjacent screw.
If the nut loosens while the car is in operation, the relative position of the adjacent blades will change
indicators and this change can be easily detected visually and the defect can be removed immediately.
The use of mother indicators in the Czech Republic was approved by the Ministry of Transport of the Czech Republic by issuing a Certificate of
approval of the technical qualification of the type of equipment and vehicle components No. 2944
