Snap fasteners (also known as press studs or snaps) fasten with a single press and do not require a buttonhole. They are perfect for jackets, children's clothes, bags, and garments made of fabrics where making a buttonhole is difficult. The method of attachment depends on their type.
Parts of a snap fastener
Most metal snap fasteners consist of 4 parts: a cap and a "stud" part for the top fabric, and a socket and a "female" part for the bottom. The cap is the visible decorative part, while the other three provide the fastening.
Sew-on snap fasteners
These are sewn like a regular button – through the small holes along the edge. Sew the "male" half onto the wrong side of the top layer, and the "female" half onto the right side of the bottom layer, exactly opposite it. No tool is needed.
Attachment with a tool or press
- Mark the exact positions on the top and bottom fabric.
- Punch a small hole (for thick fabrics) or push the prong of the cap through the fabric.
- Place the "male" part onto the prong and press it with the manual tool or press until the prong flares out.
- In the same way, attach the base and the "female" part to the bottom fabric.
- Check the fastening – a clear "click" should be heard.
For mass production, a press with appropriate dies is used, while for single pieces, a hand tool with a hammer is used.
How to remove snap fasteners
Using pliers, carefully open the flared prong from the wrong side and remove the parts. The hole in the fabric usually remains – the new snap can be placed in the same spot or slightly to the side.
