Specific torque specifications are provided by most
component manufacturers to prevent over tightening
and under tightening of bolts and nuts. Park Tool TW-5
and TW-6 Torque Wrenches are high quality, ratcheting,
click type torque wrenches that accurately measure and
apply the proper amount of torque to a bolt or nut.
TORQUE WRENCH USE
1. Determine required torque for threaded fastener
(consult component manufacturer for recommend-
ed torque specifications).
2. Flip ratchet lever to the right if turning wrench in a
clockwise direction. Flip ratchet lever to the left if
turning wrench in a counter-clockwise direction.
3. Pull locking ring to "unlock" position.
4. Turn locking ring until desired torque setting is
displayed by cursor (red line) in scale window.
For the TW-5, major graduations on the scale are
in two Newton Meter increments. For the TW-6,
major graduations on the scale are in four Newton
Meter increments.
5. Push locking ring to "lock" position.
6. Install desired bit (not supplied) onto square head
of torque wrench. The TW-5 accepts 1/4" drive bits
and 3/8" drive bits (with the included adapter).
The TW-6 accepts 3/8" drive bits.
7. Place bit and wrench onto bolt or nut to be
tightened. Grasp handle of torque wrench and
turn with steady force until a "click" is heard and/
or felt. Immediately release force from torque
wrench after "click" .
8. Dial torque setting to lowest point on scale after
each use. Also, dial setting to lowest point when
storing torque wrench.

TORQUE CONVERSION
TABLE AND FORMULAS:
measure torque in Newton Meters, which is the force
of one Newton on a lever that is one meter long. A
table on each wrench can be used to quickly convert
from Newton Meters to Inch Pounds, another common
unit of measure. Conversion formulas for converting
Newton Meters to Foot Pounds, Inch Pounds, and
Centimeter Kilograms are listed below:
