How to Make a Spanner Wrench

A spanner wrench is one of the most useful tools in any workshop. It’s a handheld tool that you can use to turn nuts and bolts. But what if you need to tighten or loosen a nut but don’t have access to your workshop? In this guide, we will show you how to make a spanner wrench with your household objects.

What Is a Spanner Wrench?

A Spanner Wrench is an eight-inch long, one-inch wide flat metal bar that usually has two holes drilled in it for use with bolts or nuts. It can be used to remove and install threaded fasteners by turning the head of the bolt back and forth against its threads until tight enough to loosen or tighten them.

Oftentimes, you may find yourself looking at wrenches in different stores wondering which one will work best for your needs without breaking your budget. Fortunately, there are many kinds of wrenches on the market today all designed specifically to meet individual’s requirements whether it’s plumbers tools or automotive mechanics tools as well as ones made from other materials like plastic.

What a Spanner Wrench is Used For

A spanner wrench can be used to tighten or loosen nuts and bolts. It’s also very useful when you need a tool that’s portable, as it allows you to use the same force on all kinds of different sizes of objects. This means you don’t have to buy multiple tools to do the same job.

Steps for Making Your Spanner Wrench

Step 1

Create a loop in one of the pieces of wire, and place it over your fingers. Then bend the ends of both wires so that they form an “X.” Leave about four inches on each side. The idea is to create two pairs of loops with space for a hook connecting them together at their center point. If you want to be precise, use pliers or wire cutters to remove any excess from these bends.

Place this set under the other piece of wire and press down firmly with your left hand (or right if you’re left-handed). This step will ensure that the hooks are secure enough not to slip out when manipulated later on during assembly steps.

Step 2

Cut a length of wire from the second piece that is about eight inches in length. Hold it between your left thumb and forefinger while simultaneously pressing on one end with a small pair of needle-nose pliers (you may also use wire cutters). Slowly pull down so as to create a looping motion as you do this, then place an index finger at the top coil for extra support. Be sure not to let go of the other side yet!

Step 3

Grasping firmly onto both ends, take hold of these loops with your right-hand fingers, and twist them together until they merge into one continuous strand. The process should be relatively easy if done correctly; just make sure to keep pulling steadily downwards using even pressure all around. This should produce a tight braid, which should start to resemble the pattern of our finished product.

Step 4

When you’ve got it done and wrap your fingers around the now braided steel wire, release the loops from one hand in order to create two separate pieces that are each about eight inches long.

Step 5

Place them together so they overlap evenly with both ends pointing upwards this time; then take hold of these two new coils using needle nose pliers or any other type of pincer grip tool as before (this will be much easier if you’re using the latter). This time when twisting them together into one single strand, make sure not to let go until you achieve an even consistency once more – otherwise, we might end up with a messy, uneven, and probably useless-looking result.

Step 6

Now take one of the loops in your left hand (assuming you’re right-handed) and wrap it tightly around both ends to make a loop at least an inch long; then do the same with the other end.

Take hold of these two coils again by using needle nose pliers or any appropriate grip tool for removing nails from woodwork blobs etc. But this time uses them to twist once more – only this time we’ll try not to let go until we’ve created what resembles a small rope about eight inches long!

Step 7

Trim off the excess wire so that our new spanner wrench will be just less than four feet in length when done, threading on some sort of eyelet or hook to one end so that we can hang it on a nail and then snip off the other.

Step 8

Now take your first loop from the left hand (the one you made by wrapping tightly around both ends) over the second coil in your right hand, which is still coiled loosely; likewise with the next two loops, and finally last two coils of wire. Hold onto these four loops again using needle nose pliers etc., but this time twist them together as tight as humanly possible while pulling hard enough for everything else to stay put!

Frequently Asked Question

How to Figure Out the Size of Spanner Wrench?

The size of the wrench depends on the size of the bolt or nut you need to turn. The general rule of thumb is that you can use a spanner wrench with an opening size that’s about one-half the size of a bolt or nut.

Why Are Some Wrenches So Expensive?

It’s because when they’re made by hand at the factory level (or sometimes even in your garage), each one takes hours to produce. That means more production time and more money coming out of your pocket! Lucky for us, we have this handy guide on how to create a cheap version using household items – no tools required!
