Sealey Torque Stick Set - 5 Pcs - 1/2"" Square Drive

These torque sticks are designed to prevent over-tightening of fasteners, specifically wheel nuts, when used with an impact wrench. They are calibrated to 'break' or limit the applied torque at a specific value.

Each torque stick is color-coded and rated for a specific torque value. You should consult your vehicle's service manual for the manufacturer's recommended torque specification for wheel nuts and select the torque stick that matches or is closest to that value.

No, these torque sticks are specifically designed for use with powered impact wrenches (air or electric). They function by the controlled flexing and breaking of the stick under the rapid impact force.

The twist distortion marking is a visual indicator of the torque stick's serviceability. If the marking shows significant twisting or distortion, it suggests the stick has been stressed beyond its intended limit and may no longer provide accurate torque, indicating it's time for replacement.

While each stick is manufactured to precise specifications and color-coded for specific torque values, they are not typically individually calibrated for a specific tool's output. Their accuracy relies on the manufacturing tolerance and the correct usage with an appropriate impact wrench.

It is recommended to store the torque sticks in the provided case. This protects them from damage, keeps them organized, and helps prevent premature distortion that could affect their accuracy.

The product information states a 'Lifetime guarantee*'. Please refer to the specific warranty terms and conditions provided by Sealey for details on coverage and exclusions.

Verify that the correct torque stick is selected and fully engaged with both the impact wrench and the socket. Ensure the impact wrench itself is functioning correctly and not set to maximum power if it has adjustable settings. Check the torque stick for visible distortion, as a compromised stick may not break at its rated torque.

Inspect the torque stick for excessive twisting or distortion. A stick that has been overused or misused may lose its calibration. Also, ensure the impact wrench is providing adequate power; some wrenches may have variable power settings that need to be adjusted appropriately.

Ensure you are using a 1/2" square drive impact wrench and socket. Check for any debris or damage in the drive square of the impact wrench or the torque stick's receiving end, and clean if necessary. Do not force the fit.
