What should I look for in a torque wrench?
Here are a few things you’ll want in a good-quality torque wrench:
- A robust lever arm for torque applications of 20 to 150 lb-ft.
- A grippy handle for situations where grease or oil has made things slippery.
- An ISO 6789 accuracy certificate (plus or minus 4 percent for up to 25,000 cycles).
How do you maintain a torque wrench?
Always keep your torque wrench dry and store it in an appropriate case to protect it from chemicals, grime and dust. Before storing, make sure to wipe down your wrench with a clean cloth as residue liquid could damage or corrode the wrench over time if left unattended.
