TWH-N Accessories

Easy to fit square drive conversion kits
Extended reaction arms with choice of length
Removable handle kits

Hi-Force SDC square drive conversion kits, suitable for Hi-Force TWH-N hexagon drive hydraulic torque wrenches are available for all models, excluding TWH430N. All models are supplied complete with an easily attachable reaction foot and a standard hexagon AF size adaptor, suitable for fitment to a commonly used size of imperial or metric ratchet head, per tool type (see table below for more details). These SDC kits provide the most flexible and cost effective method of converting a female hexagon drive hydraulic torque wrench into a square drive wrench and are available in 1", 1 1/2" or 2 1/2" square drive sizes.

Manufactured from aluminium, the lightweight extended reaction arms offer in-line reaction outside of the standard range of reaction points, thus increasing accessibility of TWH-N wrenches for applications in confined spaces.

Removable handle kits allow users to better support the tools during operation.
