FAQ
Q: How often should I calibrate my torque wrench?
A: Torque wrenches should be calibrated annually, or more frequently if used heavily or in critical applications.
Q: What is the difference between a click-type and beam-type torque wrench?
A: Click-type wrenches provide an audible and tactile “click” when the preset torque is reached. Beam-type wrenches use a visual indicator on a beam to show when the torque is reached.
Q: How do I choose the right drive size?
A: Choose a drive size appropriate for the fasteners you’ll be working with. 1/4″ is for small fasteners, 3/8″ for general use, 1/2″ for larger fasteners, and 3/4″ for very large and heavy-duty fasteners.
Q: What does ±3% accuracy mean?
A: This indicates the wrench’s potential deviation from the set torque value. A ±3% accuracy means the actual torque applied could be within 3% above or below the set value. Lower percentages indicate better accuracy.
Q: Can I use a torque wrench on all types of fasteners?
A: While torque wrenches work on many fasteners, it’s crucial to use the correct socket size and type for the fastener to avoid damage.
Q: How do I maintain my torque wrench?
A: Keep your wrench clean and store it in a safe place, away from moisture. Regular calibration is crucial for maintaining accuracy. Avoid dropping or impacting the wrench as this could damage the internal mechanism and compromise its accuracy.
