USE OF ADAPTORS, EXTENSIONS AND UNIVERSALS
Anytime an adaptor, extension or universal is used with a torque wrench in such a way that fastener
distance is different than torque wrench square drive distance at calibration, an adjustment to head
length is required to get a proper fastener torque reading.
When using wobble extension or a universal, do not exceed more than 15 degrees of offset from
perpendicular drive. Do not use a long extension with flex-drive at full flex.
CALIBRATION
Contact your Snap-on sales representative for calibration services.
CERTIFICATION
This TechAngle

Steel Micro wrench was calibrated at factory using torque measurement
instruments that are traceable to National Institute of Standards and Technology (N.I.S.T.). Torque
parameters comply with ISO 6789-2003 and ASME B107-28-2010. Note: no U.S. or International
Standards exist for angle wrenches. Angle calibration was performed on an angle gage with ±1
degree accuracy at each 45 degree indexing point throughout 180 degrees of rotation.
