The 9point8 TorqueKey
is an innovative, inexpensive alternative to costly torque wrenches. Currently available in 4mm Allen hex, one
of the most common sizes on bicycles.
The TorqueKey operates
by correlating the deflection of the key to a known torque scale. The more the key defects, the more torque
is being applied to the fastener.
The Torque can be read
off the scale, when the bottom edge of the key aligns with the scale
value. This fastener is at 6Nm.
