Understanding How Lobster Clasps Work

Lobster clasps are commonly used in jewelry making as a secure way to fasten bracelets and necklaces. Understanding how these clasps work can help you fix any issues that may arise, such as a faulty spring mechanism.

Let’s take a closer look at the basic components of a lobster clasp and how the spring mechanism functions.

Basic Components of a Lobster Clasp

A lobster clasp consists of several key components that work together to ensure a secure closure. These include:

  • The clasp body: This is the main body of the clasp that attaches to one end of the jewelry piece.
  • The lever: Located on the side of the clasp, the lever is used to open and close the clasp.
  • The spring mechanism: This is the component responsible for the clasp’s ability to automatically close and lock.
  • The ring: The other end of the jewelry piece is attached to a ring, which is then secured inside the clasp body.

Now that we have a better understanding of the basic components, let’s dive into how the spring mechanism works.

How the Spring Mechanism Works

The spring mechanism is the heart of the lobster clasp, providing the necessary tension to keep the clasp closed. It consists of a small spring inside the clasp body that is compressed when the lever is opened.

When the lever is released, the spring expands, causing the clasp to close and lock securely.

If you’re experiencing issues with a lobster clasp spring, it’s important to first check for any debris or dirt that may be preventing the spring from functioning properly. Gently clean the clasp using a soft cloth or a toothbrush to remove any buildup.

If cleaning doesn’t solve the problem, you may need to replace the spring altogether. It’s a good idea to consult a professional jeweler who can assist you with this process. They have the expertise and tools necessary to fix or replace the spring, ensuring your lobster clasp functions as good as new.

Gathering Necessary Tools and Supplies

When it comes to fixing a lobster clasp spring, having the right tools and supplies is essential. Here are some of the items you will need:


Pliers are a must-have tool for fixing a lobster clasp spring. They come in various sizes and shapes, but needle-nose pliers are especially useful for this task. These pliers have a long, narrow tip that allows for precise movements, making it easier to work with small components like springs.

You can find pliers at your local hardware store or online.

Replacement Springs

If your lobster clasp spring is broken or damaged beyond repair, you will need to replace it. It’s a good idea to have some replacement springs on hand before attempting to fix your clasp. You can find these springs at jewelry supply stores or online.

Make sure to choose a spring that matches the size and style of your lobster clasp.

Jeweler’s Screwdriver (Optional)

While not absolutely necessary, a jeweler’s screwdriver can come in handy when working with delicate jewelry components like lobster clasps. This tool allows you to tighten or loosen screws that may be holding the clasp together.

If you don’t have a jeweler’s screwdriver, you can use a small flathead screwdriver as an alternative.

Magnifying Glass (Optional)

If you have trouble seeing small details or if you want to ensure precision while working on your lobster clasp spring, a magnifying glass can be a helpful tool. It can help you spot any tiny cracks or imperfections in the spring that may not be visible to the naked eye.

You can find magnifying glasses at hobby stores or online.

Remember, having the right tools and supplies will make the process of fixing a lobster clasp spring much smoother and more efficient. So, gather everything you need before getting started!

Removing the Broken Spring

Prying Open the Clasp

When it comes to fixing a lobster clasp spring, the first step is to carefully pry open the clasp. This can be done using a small flathead screwdriver or a pair of needle-nose pliers. Gently insert the tool into the small gap between the clasp and the ring, and apply slight pressure to separate them.

Be cautious not to apply too much force, as this may cause damage to the clasp or the spring.

Removing the Spring

Once the clasp is open, the next step is to remove the broken spring. The spring is usually located inside the clasp, and it may be loose or tangled. Carefully untangle or remove the damaged spring from the clasp.

If the spring is broken into pieces, make sure to collect all the fragments to avoid any future complications.

Cleaning Out Debris

After removing the broken spring, it is important to clean out any debris or dirt that may have accumulated inside the clasp. This can be done by using a small brush or a toothpick to gently remove any particles. Cleaning the clasp will ensure that the new spring fits properly and functions smoothly.

Remember, repairing a lobster clasp spring requires patience and precision. If you are unsure about the process, it is always recommended to seek assistance from a professional jeweler. They have the expertise and tools necessary to fix the clasp without causing further damage.

Finding the Right Replacement Spring

Measuring the Original Spring

When it comes to fixing a lobster clasp spring, the first step is to accurately measure the original spring. This is important because finding a replacement spring that matches the dimensions of the original one is crucial for a successful fix.

To measure the spring, you can use a ruler or a caliper to determine its length, width, and thickness. It’s essential to be as precise as possible to ensure a proper fit for the replacement spring.

Matching Dimensions and Gauge

Once you have measured the original spring, the next step is to find a replacement spring that matches both the dimensions and the gauge of the original. The dimensions refer to the length, width, and thickness of the spring, while the gauge refers to the wire thickness.

It’s important to note that different lobster clasps may have different sizes and gauges, so it’s crucial to find a replacement spring that matches the specific lobster clasp you are working with.

Material Considerations

When looking for a replacement spring, it’s important to consider the material of the spring. Lobster clasp springs are typically made of stainless steel or brass, as these materials offer durability and resistance to corrosion.

Stainless steel springs are known for their strength and longevity, while brass springs are preferred for their aesthetic appeal. Consider the material that was used for the original spring and try to find a replacement made from the same or a similar material for the best results.

It’s worth noting that there are various online retailers and jewelry supply stores where you can find replacement springs for lobster clasps. These websites often provide detailed product descriptions and specifications, making it easier for you to find the right replacement spring for your lobster clasp.

One such website is Fire Mountain Gems, which offers a wide selection of jewelry findings, including replacement springs for lobster clasps. Remember to check the dimensions, gauge, and material of the replacement spring to ensure a proper fit and successful fix for your lobster clasp.

Installing the New Spring

Once you have obtained a replacement spring for your lobster clasp, it’s time to install it. Follow these steps to ensure a successful installation:

1. Inserting the New Spring

Begin by opening up the lobster clasp. Take the new spring and position it inside the clasp, making sure it aligns with the existing mechanism. Gently slide the spring into place, ensuring that it is securely inserted. Take care not to force it too much, as this could damage the clasp.

It’s worth noting that different lobster clasps may have slightly different mechanisms, so be sure to consult the manufacturer’s instructions or seek guidance from a jewelry professional if you encounter any difficulties.

2. Testing the Mechanism

After inserting the new spring, it’s important to test the clasp to ensure that it is working properly. Close the clasp and observe if the spring provides enough tension to keep it securely closed. Open the clasp and repeat the process several times to ensure that the spring is functioning smoothly.

If you find that the clasp is still not closing properly or feels loose, you may need to readjust the spring or consider replacing it with a different one. Remember, a properly functioning lobster clasp should securely hold your jewelry in place without any risk of it accidentally opening.

3. Closing Up the Clasp

Once you are satisfied with the installation and testing of the new spring, it’s time to close up the clasp. Ensure that the spring is in its correct position and that the clasp is aligned properly. Gently push the two sides of the clasp together until you hear a click or feel it securely close.

It’s always a good idea to give the clasp a final inspection to make sure it is properly closed and that the spring is still in place. This will help prevent any potential accidents or loss of your jewelry.

Remember, if you are unsure about any of these steps or encounter difficulties during the process, don’t hesitate to seek advice from a professional jeweler. They have the expertise and tools to assist you in properly fixing your lobster clasp spring.


With the right tools, some patience, and a new spring, you can get your lobster clasp working again in no time. Understanding how the spring mechanism functions is key, as is finding an accurate replacement spring. Take your time removing the old spring and installing the new one.

With some care and a steady hand, you can save yourself the cost and hassle of replacing the whole lobster clasp.

Avoid exposing your jewelry to chemicals and moisture, store pieces properly when not in use, and consider having clasps professionally repaired or reinforced if needed.
