SPK  PRE-SET TORQUE WRENCHES
Audible and tangible "CLICK" when the set torque is reached,
assuring a securely tightened joint. This series is well-suited for production line use.
FEATURES
A single function wrench, used for a single setting combination of fastener size and torque setting.
Most suited for tightening multiple same-size fasteners at the same torque in a production line.
Setting confirmation unnecessary.
Can be used effectively in confined spaces.
Tightening to set torque only in the direction of the arrow indicator, but can be used    for general tightening in the other direction as well.
Accuracy: +/-3% of pre-set value.
USING AN SPK WRENCH
With the wrench head completely engaging the fastener, and your grip centered on
the groove in the wrench handle, pull the wrench in the direction indicated by the
arrow on the wrench.
When the pre-set torque is reached, there will be an audible and tangible "click" and
for a split second the wrench will suddenly require less force to pull.
Continuing to pull the wrench further will add torque over the setting.
