K3 Basic Pliers & Plastic Snaps Starter Kit

Choosing the Right Plastic Snap Size

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.

Dimensions of Size 20 Snap Parts

The 3 most commonly used sizes, in the order of popularity, are:

Size 20 regular length
Size 20 extra long (for thicker material)
Size 16 regular length (for thinner material)

Size 20 (12.4mm or 1/2" cap diameter)

Size 20 Regular Length (5.6mm prong) is often used for lightweight to mid-weight fabric that isn't prone to tearing including baby diapers, menstrual pads, bibs, regular clothing, and household projects. This is the most popular size of plastic snaps and is a good size to start with for most projects since most commonly used fabric fall within the desired thickness for this length. This size has a strong grip so if you're working with more delicate fabric at risk of tearing, consider size 16.

Size 20 Extra Long (6.2mm prong) is recommended for slightly thicker & denser material like double layers of standard marine vinyl for key fobs, medium weight leather, and chinese prefold diapers. (Some versions of these material may be so thick that they'll need larger/longer snaps.)

Size 16 (10.7mm or 7/16" cap diameter)

Size 16 Regular Length (4.6mm prong) is most commonly used for projects that require a looser grip, such as doll clothes or reinforced stretch jersey.

Size 16 Extra Long is available in lengths ranging from 5.2mm - 7.2mm long for thicker material.

Size 22 (14.1mm or 9/16" cap diameter, 7.0mm prong)

A larger snap which can be used in similar situations as size 20 long-prong, or in situations where size 20 long-prong is still a little too short.

Size 24 (14.8mm or 9/16" cap diameter, 7.5mm prong)

Our largest, strongest snap which 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.

How to Attach Plastic Snaps

Best Snap Kit Ever

I purchased 2 other kits, which I returned, before I decided to go with KAMsnaps. There was no need to look any further. The shipping was amazing! I practiced with one snap set and that was all I needed. This snap kit is the BOMB! I only screwed up half a set and it was my fault...put it on backwards to the mate. I will never use another brand. These beautifully colored snaps are being used on the harnesses that I make for my little rescue Chiweenie. She's a hard fit so I custom make these for her. The colors of the high quality snaps are gorgeous and the attachment tool is easy on the hands, requires a medium grip, and you're finished! Instructions are clear and concise. Their dedication to animal rescue, foster and support is the absolute icing on this cake! We so appreciate their being a voice for the voiceless and helper for the helpless. We have been involved in rescue and transport for many years now and we're getting up in age but can't bear to leave it. We are proud to support this company in our own small way. Thank you so much! For some reason they red and white one with the white snaps would not upload. So I just showed a picture of the front of one of the others so you would know what the front looked like.
