Snaps are not one-size-fits-all. If your snaps are too long for your fabric, they won't close properly. If they're too short, they'll fall off. For this reason, it's important to choose the proper size / length for your material.
Which size works best for you will depend on a number of variables, such as the fabric you are using, its density and compression levels, how hard you are able to press, and your own personal preference. For these reasons, we are unable to provide specific size recommendations for every scenario.

Size 24 is our largest, strongest snap and should only be used in very heavy duty applications with thicker material such as canvas tote bags, nylon webbing, dense leather and thick jackets. Because the grip is so strong, it can tear through more commonly used fabric.
