We get a lot of questions regarding the differences between our line 16 Glove and Segma snaps (B0162 and B0163 respectively).
There are a couple differences in the two snaps:
The button studs are different sizes. The Glove snap is #21 and is the smaller of the two, and the Segma is a #22.
The length of the flange is different. For the Glove, 0162, the length is 1/8”, but for the 0163 Segma, the length is 3/16”. The length of the segma is the reason this snap is used primarily for belts.
The 0163 Segmas have a “finished” cap on both sides of the snap, while the 0162 only has a finished cap on the front side.
They require different setters. Glove snaps need #8103 Segma Snap Setter, while the Segma needs #372768 setter.
