Comparing Different Torque Wrenches / Wheelbolt Indicators - Expert Analysis

The four products in this range split into wheel bolt indicators (three variants) and one torque wrench kit — each doing a different job.

17mm vs 19mm indicators

Both use the same directional-arrow design to show bolt movement at a glance, and both fit AL-KO and BPW standard bolts — the only difference is the hex size, so check which size your wheel bolts use before ordering.

Bailey-compatible indicators

A separate pack specifically for Bailey-compatible bolts, also fitting AL-KO and BPW standards, in the same pack-of-10 format.

Torque wrench safety kit

Unlike the indicator packs, this is a complete kit — wrench, socket, extension bar and 20 indicators — for torquing wheels yourself rather than just monitoring them afterwards. It explicitly isn't suitable for Bailey caravans, which need product code 2875 instead.

Which to choose

If you already torque your own wheels correctly, indicators alone are enough to monitor them. If you don't have a suitable torque wrench, the safety kit gives you everything needed to do the job properly, plus indicators to check afterwards.
