Metal snap fasteners for firm fabrics — jackets, bags and workwear hold with them even under strain. The size comes to Ø 15 mm. Inside the pack are 10 pieces. Made from brass.
On bags, cases and pouches they hold a flap shut without anyone sewing where strain will later build. They are set from both sides of the fabric; only then does the fastening sit tight. A test on a scrap shows whether the layer holds. Before setting, look at the spot: two layers plus interfacing hold better than one single layer of thin cloth.
What Prym Nähfrei-Druckknopf Anorak, 15mm, alteisen 390310 is suitable for
- Cuffs, hoods and necklines
- Flaps on bags and cases
- Alterations to finished garments
Frequently asked questions
What tool do I need?
Prym offers pliers and tool sets to match each size. The pliers work more quietly than hammer and anvil and hit more accurately, because the part sits in the insert and cannot slip while pressing.
Which fabrics do they suit?
From jersey to denim, most things work. Thin cloth needs a reinforcement under the fastening, or it will tear out over time. Two layers plus interfacing make the safe build-up.
Can a badly placed fastener be removed?
Yes, there is removal tooling for that. It rarely comes off without a trace, so test on a scrap first until position and pressure are right.
What spacing should I keep?
As a rule of thumb the first one sits about its own width from the edge, the rest at even intervals. Marking with chalk or a pen keeps the row straight.
