In order to tighten your kitchen faucet handle, you must be ready with a dowel rod 6 inches long. And its thickness should be either 1 inch or ¾ inch. Since the softer Woods wear out easily, don’t go for that. Try to use a hardwood dowel, like- oak.

You don’t have to cut the dowel perfectly, just make the incision in half long ways. It would be much better if you cut it closer.

Fit Your Allen Wrench:

Strike the center of one-half of the dowel. Then see where the short side of your Allen wrench is so that you can remove wood from it. To do so, you will need a small chisel. If the wood is not removed from your Allen wrench, it may fail to fit into the slot.

Put The Handle Together:

In the next step, you will need to insert the screws. But before that, drill some holes at the end of your handles. When you are doing it, make sure the grill does not reach both sides, the other side should remain apart.

Now it’s time to insert the screws. Go for that excuse that has a shorter dimension than the handle’s width.

Make It Smooth:

Now make the screws smooth enough using a grinder or a file and remove all the splinters with sand. This is all. Your handle is all set to use.
