In the absence of a wrench, what can be used as an alternative?

All of it seems to be very straightforward, doesn’t it?

What happens, incase you don’t have the right tools for this work or are unable to book a visit to your local home improvement store to get them?

Don’t be concerned; this does not imply that you will be unable to complete the task.

There are a variety of alternatives that could be found all across house that could be used to complete the task.

Take advantage of your inventiveness and imagination to use the following methods to fasten the bolts and restore functionality to your faucet.

Duct tape

Duct tape has a surprising number of uses, which you might not expect at first glance.

You might be even more amazed to realize that it could be very effective when it comes to securing the bolts on the faucet in your kitchen.

1. Make some room for yourself

  • Keep in mind that having the appropriate workspace to work in is just as crucial as any other.
  • In order for the duct tape to be effective, it must be applied to an appropriate amount of space.
  • That entails making the most of the available space underneath the sink, so you’ll have as much room to move your arms around as possible.

2. Take your strips and tear them

  • After you’ve cleared the area, you have to tear off your strips.
  • It is suggested to try with strips that are approximately a foot in length.
  • Ensure that you trim the strip down the middle, so you’ll have two thin, twelve-inch strips to function with.
  • Attach one strip to the rear of the other to form a single, very long and durable piece.

3. Curl across the nut

  • Use the thickest section of your new tape and curl it across the nut of the faucet.
  • Be careful to keep a tail of almost 7-8 inches at the tip of the tape, pushing the tape hard against the nut to verify that it sticks correctly to the nut.

4. Yank the tail as hard as you can

  • Next, yank on the tip of the duct tape to secure the nut .
  • It’s safe to remove the tape after you’re certain that the night cannot be turned any farther without overtightening it.
  • Prior to putting anything aside, just check to see that the fixture is steady and not dripping any more water.

Zip ties and coins are two of the most commonly used items

You may also complete the task using either a zip tie or a few coins that you have lying about your home.

It may take a little more time and work than some of the other approaches, but it is still possible to complete the task.


  • When you consider how many things could be secured with zip ties, you may be amazed at how many of them there are.
  • Nonetheless, they go beyond simply organizing cables and affixing hubcaps to the wheels.
  • All that is required is that you place the zip-tie across the faucet’s nut and tighten it as much as you possibly can.
  • Next, you have to grasp onto the end of the zip-tie and pull, much like you would with duct tape.
  • Continue to pull on the zip-tie till the nut is securely fastened.


  • In the event that you are serious about not going to the shop and do not have any of the items indicated above, there is one final option: two coins.
  • To be precise, a set of coins (assume quarter-sized) may be useful considerably more often than you would imagine.
  • All that is required is that you set them on each side of the faucet nut.
  • Once you’ve done that, place the coins between your knuckles with the help of your index and middle fingers.
  • This is intended to provide you with more grip as you rotate.
  • Next, rotate the coins in a way that should enable the nuts to become more tight.
  • Continue rotating until you are unable to spin any more, and then test the faucet to check that it is secure enough to prevent leakage.
