The 72-tooth internal gear requires only a 5-degree swing arc, allowing for mechanical fastening in confined or tight engine spaces.
Laser-etched Dual Range lines ensure effortless reading even in low-light garages
Chrome vanadium steel contains chromium, which naturally helps the tool surface resist rust and corrosion during daily storage
Shaped to match natural hand positioning, providing a secure hold during high-torque applications
Are these torque wrenches pre-calibrated, and how do I verify the accuracy?
Yes. Every wrench in this 3-piece set is pre-calibrated to ±3% accuracy. You can verify this using the individual, serialized calibration certificate included inside the storage case.
Will using the included extension bars change the torque reading?
No. Straight extension bars do not change effective lever length. The torque reading remains exactly the same. It ensures accuracy for deep spark plugs.
What are the specific measurement units for the smallest 1/4" drive wrench?
It features a 20–220 in-lb scale. It provides precision for bicycles, carbon fiber components, and electronics, preventing over-tightening on fragile fasteners.
What is the best way to store these wrenches to maintain their precision?
Reset the scale to its lowest setting after each use (e.g., 10 ft-lb for 1/2" drive). This relieves internal spring tension and preserves factory calibration.
How will I know when I have reached the preset torque?
You will hear a "click" and feel a physical impulse. Stop applying force immediately. It remains distinct even in noisy garages.
