Attaching Snap Fasteners: A Step-By-Step Guide

how to apply plastic snap fasteners

Plastic snap fasteners, also known as KAM snaps, are a fun, colourful, and inventive alternative to buttons. They are easy to install and can be used on a variety of items, from baby bibs and clothing to purses, bags, and pillow covers. They are a great option for baby items as they are easy to open and close, even for little hands, and provide a strong hold. With no sewing or complicated buttonholes required, these plastic fasteners offer a simple and sturdy closure that can be installed in less than a minute. This introduction will guide you through the process of applying plastic snap fasteners and the various tools needed for a successful installation.

Mark where you want your snap

Marking the position of your snap fastener is an important first step in the installation process. You should carefully consider the placement of your snap fastener, as the fabric will be marked by the hole you poke to attach it and you will not be able to use the snap again. If you are installing snap fasteners for the first time, it is recommended to practice on a scrap piece of fabric first. This will allow you to get a feel for the process and how the pliers work.

When marking the position of your snap, consider the overall design and functionality of your project. Snap fasteners consist of two identical caps (front and back), a stud, and a socket. The caps generally go on the outside of the project, while the stud and socket are on the inside. The stud and socket connect to form a sturdy closure. Mark the position of each component of the snap fastener, ensuring proper alignment and spacing between the pieces.

For accurate marking, you can use tailor's chalk or a fabric marker to indicate the exact location of the snap. Place a small dot or cross where each hole will be poked. You can also use a ruler or measuring tape to ensure precise spacing and alignment between the snaps. If you are working with a patterned fabric, you may want to position the snaps in a way that complements the design. For example, you could centre the snaps within a specific motif or align them with the repeat of the pattern.

When marking the position of the snap, consider the thickness and structure of the fabric. If your fabric is not firm enough, you may need to reinforce it with interfacing before placing the snap. This will provide a stronger base for the snap fastener and help ensure a secure attachment. By taking the time to carefully mark the position of your snap fastener, you can achieve a neat and professional finish for your project.

Poke a hole where you will position your snap

When applying plastic snap fasteners, it is important to carefully poke a hole where you want to position your snap. This is a crucial step in ensuring the snap is secure and properly attached. Here's a step-by-step guide to help you through the process:

Start by marking the desired location of the snap on your fabric. Use a fabric marker or tailor's chalk to indicate the exact spot where you want the snap to be placed. This will serve as your guide for the next step.

Take an awl or a sharp tool and carefully poke a hole through the fabric at the marked location. Make sure the hole is not too big, just large enough for the prong of the snap to fit through. Be gentle and precise during this step to avoid damaging the fabric or creating an oversized hole.

It is important to note that the fabric will likely be marked by the hole you create, so ensure you are confident about the placement before proceeding. The hole will be necessary to securely attach the snap, and the snap typically cannot be removed and reused without leaving a hole.

After poking the hole, it's time to insert the snap. Choose the appropriate snap prong for your project, considering the thickness of the fabric. Position the snap backing piece with the prong through the hole, with the flat side facing down onto the fabric. Ensure the prong protrudes through the fabric.

Once the snap prong is in place, you can proceed to secure it in place following the specific instructions of your snap fastener kit. Remember to test the snap once it's attached to ensure it opens and closes with a satisfying "snap" sound, indicating it has been placed correctly.

By carefully poking a hole and following these steps, you can confidently attach plastic snap fasteners to your desired items, creating a secure and functional closure.

Push the prong through the hole

To apply plastic snap fasteners, you will need to purchase snap fastener pliers, which are a small initial investment. You can find these at Amazon, eBay, or smaller fabric and patchwork shops. You will also need to purchase the plastic snap fasteners themselves, which come in a variety of colours and sizes. For standard size 20 snaps or smaller, use the smallest rod (A). The widest one is for snaps size 22.

Now, to the process of pushing the prong through the hole:

First, mark where you want your snap fastener to be positioned. Then, poke a hole where you will place the snap. You can pierce the fabric with the plastic pin (prong) of the cap, or you may need to use an awl. Take one of the caps and push the prong through the hole. The caps generally go on the outside of the project, but this depends on what you are sewing. The stud and socket are on the inside of the snap pair. Place a stud over the post of the cap on the other side of the fabric. When you are closing something, push the stud into the socket, and when you are opening it, pull it out.

Now, take your pliers to attach the socket and the cap: put the flat piece of the cap inside the black tray (the divot) of the pliers. It must fit inside the divot. Make sure no part of the button sits outside of the divot. Now, match the socket with the other end of the pliers, ensuring that the indentation is away from the prong. Press down and squeeze with both hands. You will feel the prong flatten. The pliers will smoosh down the plastic prong, securing the snap.

To ensure your snaps are placed properly, there should be a clicking sound when you open and close them. If your fabric is not firm enough, reinforce it with interfacing before placing the snap.

Attach the socket onto the prong

To attach the socket to the prong, start by marking where you want your snap to be positioned. Then, poke a hole where the snap will be placed. In some cases, you can pierce the fabric with the plastic pin (prong) of the cap, but often, you will need to use an awl. Next, take the cap and push the prong through the hole. The caps are generally placed on the outside of the fabric, but this may vary depending on the project. With the prong through the hole, attach the socket to the prong from the other side of the fabric. Now, get your pliers and place the flat piece of the cap inside the black tray (divot) of the pliers, ensuring it fits securely. Then, match the socket with the other end of the pliers, making sure that the indentation is facing away from the prong. Check that no part of the socket sits outside of the divot. Now, press down and squeeze the pliers with both hands. You should see the prong flatten, securing the snap in place. You will hear a clicking sound when opening and closing the snap if it has been attached correctly.

Secure the snap with pliers

To secure the snap with pliers, follow these steps:

  • Mark where you want your snap to go, and poke a hole through the fabric. You can use the plastic pin (prong) of the cap to do this, or you may need to use an awl.
  • Push the prong of the cap through the hole from the top side of the fabric, then attach the socket onto the prong from the other side.
  • Take your pliers and attach the socket and the cap: place the flat piece of the cap inside the black tray (the divot) of the pliers, ensuring it fits securely.
  • Match the socket with the other end of the pliers, making sure the indentation is away from the prong.
  • Check that no part of the snap is sitting outside of the divot. Now, press down and squeeze the pliers with both hands.
  • You should see the prong flatten. The pliers will smoosh down the plastic prong, securing the snap in place.
  • You should hear a clicking sound when opening and closing the snap to ensure it has been placed properly.

If this is your first time installing plastic snap fasteners, it is recommended to practice on a scrap piece of fabric first to get a feel for the process and how the pliers work.
