WHCT series
Built for the recess.
When the nut sits inside a recessed flange or hard against a wall, the standard hollow head will not go on. The WHCT keeps the same power head and pump, with a working head machined thinner.
What it solves
- Thinner working head clears recesses and adjacent studs that stop a standard hollow wrench.
- The same power head as the XLCT, so a second head is an addition, not a new tool.
- H series thin body and W series body cover different access angles.
- Nut range 36 mm to 190 mm, torque up to 139,463 N·m.
Selection
Pick the size, not the pressure.
Every model in a range runs at the same working pressure, so the choice comes down to the torque or load the joint needs. The target should sit inside the model range with headroom on both sides.
| Model | Torque range (N·m) | Nut range (mm) |
|---|---|---|
| 1WHCT | 233 to 2,326 | 36 to 60 |
| 3WHCT | 345 to 3,446 | 41 to 60 |
| 4WHCT | 540 to 5,399 | 46 to 80 |
| 6WHCT | 769 to 7,691 | 55 to 85 |
| 8WHCT | 1,212 to 12,116 | 70 to 105 |
| 15WHCT | 1,992 to 19,919 | 80 to 115 |
| 25WHCT | 3,363 to 33,629 | 90 to 130 |
| 35WHCT | 5,385 to 53,851 | 120 to 145 |
| 50WHCT | 7,522 to 75,221 | 130 to 180 |
| 95WHCT | 13,946 to 139,463 | 155 to 190 |

Next step
Send the joint, not the model.
Bolt size, grade and target torque is enough. The answer comes back as a model, a pump, a socket and a price.
