The knurl is important; otherwise, wheel studs spin during tightening.

Furthermore, wheel studs cannot be welded.

Once the wheel stud has commenced spinning, the hole has been oversized.

The drum now requires replacement. It is not to insert new wheel studs into old stud holes.

If a replacement is necessary, then we recommend a drop of red locktite.

wheel nut indicatorsWhen rough roads loosen wheel nuts, the wheel rim acts as a hammer on the high tensile studs, causing them to break.

It is common for wheel nuts to work their way loose and require tightening immediately.

A simple remedy is to check the nuts every morning or, better still, insert wheel indicator tags for increased safety.

These tags quickly identify even a slight loosening of the wheel nuts.

Once the identification process is made, the simple remedy is to tighten the loose nuts.

Wheel tag indicators provide an easy visual inspection method to ensure fleet safety.

How to install wheel nut indicators

  • Re-tighten the wheel nut immediately and replace the tab in the correct position.

  1. Robert Simpson

    Yes appears to be great indicator but one still needs to do the Wheel Nut Check with your Wheel brace especially a CROSS Wheel Brace or similar like the Ttype supplied by JACO CARAVANS which was supplied with our New 2019 Jaco Journey, it is Quite good to uuse and Store in the Tunnelle Boot with the JACK ETC.

    Couplemates wheel nut indicators are great, they have saved my nuts on several occasions when towing my 6.5m boat over corrugated and rough roads in north Queensland. Checking my wheel nuts is now easier because I don’t need to get the wheel brace out and check each one, just a quick visual check and your good to go.
