A measuring tape is an essential tradies’ tool, providing accurate measurements for mechanics, construction workers, plumbers, electricians, and more.

So when something goes wrong, and your tape won’t wind or unwind, you’ll want to fix the issue quick-smart!

Follow our step-by-step guide on how to fix broken measuring tape, and you’ll be back to work in no time.

1. Identify the issue

The first step in fixing a broken measuring tape is identifying the cause of the problem. One of the most common reasons for tape measure issues is corrosion. If water, dirt, or grime has entered the case, over time, the tool will corrode and fail to function as expected.

If the blade can’t retract automatically, corrosion is the most likely reason.

Another issue involves a broken connection between the tape measure’s blade and spring. This can occur if somebody pulls too hard on the blade, splitting the two parts apart.

You can determine if a broken connection is the issue by pulling the blade out entirely. If it’s broken, it will detach from the case. 

The third possible cause is a detached hook. If you pull out the tape too far and it retracts wildly, the hook can break apart from the blade. The best solution, in this case, is a blade replacement.

2.  Repair corrosion

A homemade solution of equal parts water and white vinegar may be suitable for removing small patches of rust. If you don’t mind surface scratching, use steel wool or a wire brush dipped in the solution to clean the blade.

If the entire blade is rusty, you can scrub it down with a rust remover, such as oxalic acid. Make sure to wear rubber gloves to protect your skin! Once done, clean the blade with a lint-free rag.

3. Replace a broken spring

If you’ve identified a broken spring as the cause of the issue, thankfully, the solution is simple and takes less than ten minutes!

You’ll need:

• Replacement clock spring
• Phillips screwdriver
• Large needle-nose pliers

Start by removing all three screws from the tape measure cover’s clip side with your Phillips screwdriver. Take off the metal clip and pull apart the shell.

Next, pull upward to remove the spring housing from the plastic axle. Unravel the tape and remove the end from the attached metal tab.

Pull open the spring housing by removing the top plate. This may require significant force, but make sure not to pull too hard—the plastic tabs may break.

Now, use your needle-nose pliers to remove the old clock spring. Use the same process in reverse to place the new spring. Line up the plate so the spring aligns with the teeth and press down until it clicks in.

Feed the end of the spring sideways through the tape’s hole, twisting the housing until the tape aligns with the slot. Wrap the tape carefully around the housing, maintaining tension.

Finally, replace the blade housing, ensuring all parts line up, and re-screw using your Phillips screwdriver.

Conclusion
