Troubleshooting Common KAM Snap Problems

If you've watched the instructional videos on how to install your plastic KAM snaps but still have problems, the following troubleshooting tips may help.


1a. Snaps Not Closing (Shortening the Prong)

1b. Snaps Not Closing (Increasing Fabric Thickness)

 

2. Snaps Stopped Closing After Wash/Dry
The factory recommends heat less than about 104 F / 40 C. The heat from your dryer may cause the plastic to expand ever so slightly.  If your snaps were attached securely, this won't make a difference. But if they were on the brink of being unsecure, then the tiny bit of expansion will result in your flattened prongs sticking out too much so that they now get in the way when you try to close your snaps. Refer to Tip #1 (Snaps Not Closing).

 

3. Snaps Falling Off Fabric

 

4. Snaps are Cracking
This happens when the cap does not sit properly within the cap (bottom) die.  First, check that you are using the correct cap die.  When placing the cap on the bottom die, the cap should sit completely inside the inner cup of the die. Cracking can happen if any part of the cap is resting on the raised outer edge of the die. Refer back to the instructional videos to ensure you are using the correct die and setting the cap on the die properly.

 

5. Snaps are Uneven
If you are using basic pliers, a slightly uneven press is normal but should not affect the functionality of the snap.  If your flattened prongs are severely uneven, tighten all 3 metal screws. These screws should be checked and tightened periodically.

 

6. Snaps are Hard to Open
KAM plastic snaps are industrial grade, which means they have a very strong, secure grip. For this reason, it is always recommended that you reinforce any thin, delicate or stretchy fabric (like knits) with a sturdier material (like twill or fleece) to avoid ripping over time. Size 16 plastic snaps have a slightly gentler grip compared to the more popular size 20 if you want something a little less tight.Snapping and unsnapping several times may help loosen the snaps a tad.  Another suggestion is to use a tiny drop of Tri Flo Teflon lubricant on a q-tip to swab the interior sides of the snaps.

 

7. Tool No Longer Applies Enough Pressure
If you've been using your pliers or table press for a while with good results, then one day they just don't seem to work as well or your newly installed snaps won't close, it may be time to replace some of the parts. Just like any mechanical tool, parts may wear out over time.

Basic Pliers: The tension spring, rubber head, and cap die will wear down the most with continued use. If any of the metal screws are significantly loose, those should be replaced as well. Parts are available for K1 or K2 pliers.

Table Press: Any rubber or springs on the dies will lose their elasticity with continued use, so dies will need to be replaced periodically. Dies are available here.
