But now it’s time we change that! At Antiques Know How, we respect your money and returns! So, we made a step-by-step guide to identify and value an antique wrench! So, get your pencil and magnifying glass, and let’s do it together!

Key Takeaways

  • If you want an old, precious wrench, look for cast iron bodies, fixed jaw ends, and geometric cuts on both edges.
  • Pick jagged or alligator wrenches with an s, l, or t-shaped shaft for an old make. You can also look for brown, black, or gray wrenches to raise the value.
  • Uplift your style game, and go with branded wrenches like ‘Keen Kutter,’ ‘Deere,’ or ‘Stanley’ wrenches. These are larger, sturdier, and costlier than the rest!
  • You can get four types of wrenches: chain, monkey, pipe, or combination. Of these, pipe wrenches are costly, while the rest value up to $70.

What to Look for in Antique Wrenches?

Let’s be honest! Old wrenches are neither artistic nor carved! But it’s their solid metal parts and fixed screws bodies that make them strong! You’ll also notice a wood or ceramic grip handle at their shafts.

But what if the wrench is missing the handles? Yes, they can happen, too! So, I’ll tell you some more features to look for!

  • Central metallic shaft with round handles, and a warm screw at the top
  • 1 – 2 torque heads with fixed and adjustable ends on both sides
  • ¼ or ⅜ inch sockets with an 8 – 10 inch body below it
  • An abstract, geometric, or triangle shaped cut out on the heads and shaft
  • Signed trademarks, brand names, and sizes on the shafts and wrench head

History & Evolution of Antique Wrenches

It’s rare to have two inventors for the same tool, right? But, antique wrenches have two makers, Henry King (1832) and Solymon Merrick (1834). But Henry’s model was small and stiff, while Merrick made it flexible.

It was in the 1840s that Merrick made the first screw-adjust wrench. He added a ‘c’ opening and a notched hole on its shaft. Plus, he built nut-shaped sockets to hold the screw! But, its thin post slipped easily and needed a grip. So, down went its use, needing more designs!

Then entered Loring and Aury Gates Coes from the 19th Century! They improved the prior stuff and made the first Monkey wrench with an open-end clamp. But, these became popular and easy to get. So, you obviously won’t get high returns for them.

4 Types of Vintage Wrenches & Their Valuation

Vintage wrenches are pretty diverse! So, if you are planning to get one for your toolkit, you must know how each one works. So, let’s discuss the four main types of antique wrenches and their cost.

1. Chain Wrench

As you might guess, chain wrenches are the ones with chain sockets! They are smaller and more adjustable than others. They also have rivet joints which help you rotate and dismantle pipes easily.

But chain wrenches have more misuse and friction! So, they rust easily, lowering the value only to $50 – 60.

2. Monkey Wrench

Monkey wrenches look exactly like the vernier calipers you see today! They have a big jaw, an adjustable spanner, and a screw wrench. Plus, you get them with wood or steel handles, costing $60 – 70. So, you won’t have to worry about the cost, grip, and durability of this one!

3. Pipe Wrench

Pipe wrenches are like flat spanners that fasten or loosen pipes. They have flat threads and a 6-9” handle with a groove on each side. And, if you want to check whether your pipe wrench is antique or not, look for a nut in its groove! This will raise the value to $100 – 200.

4. Combination Wrench

Combination wrenches are multi-fold! Like, they have a U-shaped spanner at one end and a closed loop at the other. So you can use them for both pipes and screws!

They are also sturdy! And you rarely see a polished ¼ inch socket with antique models! But since these wrenches are modern and machine-made, they cost only around $40 – 50.

6 Factors to Identify & Value an Antique Wrench

Now that you know your wrench type, let’s move on to the costs! Here, we’ll discuss the age, designs, and other factors that impact a wrench’s value!

1. Old Wrench’s Date & Age

Remember how the old 1830s pipes had no fixed size? So, you’ll see flexible jaws and handles on old wrenches. Many might even have a shaft and a curved torque to mend hard-to-reach places. Plus, these have a full hand-cast iron body, making them precious!

But do you know that even the 1870s machine-cast wrenches are valuable? It’s because of their brands and box-end cuts that make the job easy!

Next are the post-modernization pieces from the 1900s. Usually, they are cheaper, but you can get self-adjusting pieces for high value.

Here are other cues for tracing your wrench’s age correctly!

How Do You Know If Your Wrench Is from the 1830s?

If your vintage wrench has a swivel head spanner and a twelve-point fastening, it’s from the 1830s. You’ll even notice that they are thin, unpolished, and have a poor grip. Ring spanners or pointed-end sections are also common in most models!

But these won’t have any logos, just like old plows. But you can still check for an engraved date on its handle! But if not, look for small threads on each jaw! These models are valued at around $200 – 300.

How Do You Spot Vintage Wrenches from the 1870s?

Look for rotating sockets and adjustable screws to spot these models! And since most of them evolved after the Industrial Revolution, they will be lighter and more flexible than others. You’ll also see a universal open-end design that hikes the value to $120.

How Do You Check If Your Wrench Is from the 1900s?

Check if your wrench has adjustable handles, straight shafts, and grooves. If yes, it’s from the 1900s! Most would also have a casting logo and patent number on their handles. So, you can verify the brand and price them for $40 – 100.

Here are some wrench patent numbers for reference!

1871151 years119596Monkey Wrench$90 – 100
1890s132 years254862Chain Wrench$60 – 90

Try to get non-cylindrical, jagged jaw wrenches for an old make.

2. Antique Wrench Head Style

Antique wrenches were not always slim and U-shaped. In fact, most older models use natural snapping heads, just like an alligator. And you might even see curved or jaw-like heads in these early 1840s models.

The next 1870s models evolved after the Industrial Revolution. It was during this period that open-end designs were famous. So, if you spot one, price it for $70 – 80.

In contrast, you’ll see minimal, flared heads and threaded collars with the 1900s models. But I advise avoiding these thin, pin-face models, as they are cheaper!

Wrench’s Head ShapeAverage Valuation
Cylindrical or Socket Shape$200 – 240
Alligator Jaw Head$100 – 120
Serrated or Jagged Head$90 – 100
C-hook Jaws$70 – 80
Open-end, U-shaped Head$40 – 50
Flared or Tube Shape$15 – 20
Crowfoot or S-curve Head$12 – 15

Pick wrench heads with a 6-point or 8-point recess for high returns.

3. Old Wrench Colors

You only see gray or chrome wrenches these days! But you’ll be surprised to know that antique wrenches had more colors. Brown, White, Copper, you name it, and you have it!

Of these, you’ll need to pay more for the oxidized black and brown wrenches. But you’ll get painted red or blue wrenches for as low as $15!

Wrench’s ColorAverage Valuation
Brown, Gray or Black$90 – 100
White or Beige$70 – 80
Copper or Orange$50 – 60
Lemon Yellow or Ochre$20 – 30
Bold Red, Navy Blue$15 – 20
Polished or Galvanized Wrenches$8 – 10

An aged, white wrench might look brown with time. So rub your finger and check for a crude, powdery finish before buying.

4. Branding

If you are confused between 2-3 antique wrench models at the auction, get the branded one, like ‘Stanley,’ ‘Wayne’ or ‘Keen Kutter.’ Why? Because their sturdy, durable designs raise the value by 10 – 20%.

But how do you check the wrench’s brand? Just rotate its shaft and look for embossed logos, signs, or trademarks. You can also get tape and measure the wrench’s shaft. If it’s more than 12-13 inches, it’s most likely branded!

Here are some antique wrench brands for your info!

5. Old Wrench Handle Style

Bare metal, handleless wrenches are cheaper than ones with handles as they hurt the fingers and loosen the grip. So wooden or metal handle wrenches are valued at around $80 – 90. Here, you can pick Oak or Ash wood handles for a superior finish.

And if you like it colored, choose ceramic handle wrenches from the 1870s. You can value these handmade handles for as high as $60.

Avoid getting wrenches with cracked handles as they lose their value by 10-12%.

6. Old Wrench Shaft Style

We are all familiar with straight, linear wrenches, right? So, it’s obviously the unique s, l, or t shaft wrenches that interest antique lovers! These wrenches also boost the user’s torque and work best in hard-to-reach places.

Here, you can value s-shaft wrenches for $200, l-wrenches for $230, and t-ones for about $300.

Which Antique Wrench Company Is the Best?

You can get good-quality, branded wrenches from Stanley, John Deere, Keen Kutter, and Wayne. Most of these cost around $200 – 250.

How Do You Clean an Old, Rusty Wrench?

You can clean a rusty wrench by soaking it in a 1:4 solution of salt and vinegar. This will soften the rust, and you can clean it with a toothbrush.

How Do I Lubricate Old Wrenches?

You can lubricate old wrenches by coating them with white lithium grease, vaseline, or WD-40 lubes.

We know how small and rusty wrenches are. That’s why we stress checking their brands, shapes, and colors to verify them. As we saw above, you can pick curved wrenches for better value. And if you want to resell them, you must keep them free from dust and mold!

Tightening or loosening screws with a wrench is okay! But won’t you need a hammer to strike them first? Join me, and I’ll tell you all about identifying vintage hammers!
