At a listed 1.3 kg with IP56 sealing, it suits mobile mechanics, tyre fitters and anyone who wants a light, weatherproof wrench for vehicle work.

Our take
Right sized torque
HiKOKI quotes up to 380 Nm for tightening and 700 Nm for nut busting, with a working range up to M20 bolts. That comfortably covers car and van wheel nuts, brake calipers and most suspension fixings. It will not match the high torque models on large plant bolts, but it is quicker and lighter in daily use.
The listing gives a length of 15 cm and a weight of 1.3 kg.
Low weight also matters when you work at arm's length under a raised vehicle. A wrench that is easy to hold steady reduces the chance of rounding a nut or dropping the tool.
Auto Stop and Auto Slow
There are four modes, with optional Auto Stop and Auto Slow. Auto Stop stops the tool after a preset time to prevent overtightening. Auto Slow reduces speed automatically once loosening is detected, so a nut does not fly off the end of a stud and disappear under the car. For wheel work, that is one of the most practical features in this guide.
Weather protection
IP56 is listed for protection against harsh weather and dust. Mobile mechanics and roadside recovery crews often work in rain, so a sealed tool is a sensible choice. It matches the bigger WR36DE on this point.
Kit and batteries
The listing supplies the body in a Stackable System Case 2, without battery or charger. It runs on HiKOKI 36 V MultiVolt packs. A smaller pack keeps the overall weight down for overhead or under car work.
The system case stacks with HiKOKI's other cases, so the wrench, sockets and a spare pack can be carried together.
When to choose something bigger
If you regularly crack seized fixings on trucks, trailers or plant, the HiKOKI WR36DE or DeWalt DCF900P2T offer far more breakaway torque. The DeWalt DCF891N is a middle ground with four speeds and around 1,000 Nm of breakaway.
Verdict
The WR36DH is a smart pick for HiKOKI users who mainly work on cars and vans and want a light, sealed wrench with Auto Slow to stop nuts flying off. For heavier fixings choose the HiKOKI WR36DE, and DeWalt owners should consider the DCF891N.
