but the torque range is still a bit high. Most other fastenings on a
bike are pretty easy to tighten "by feel" if you have mechanical
sympathy.

Torque Screwdrivers are also available (used a lot in electronic
and mechanical production environments). These have much lower
torque ranges than a wrench.

RS Components do a range, but many (not all) have no dial and
have to be set up using additional measurement equipment.
