Prym Sew On Metal Snap Fasteners - Gunmetal

These snap fasteners are made from high-quality brass.

They are designed to be sewn onto fabric using a needle and thread, utilizing the fixing hole on the stud and stitching around the edge of the socket.

Yes, the brass material is generally safe and durable. However, always ensure they are securely attached according to sewing best practices.

While primarily designed for fabric, they can be sewn onto thinner leather or faux leather. For thicker materials, alternative attachment methods like rivets might be more suitable.

The 'flanged stud' is the part that connects to the socket, and it has an integrated hole which makes it easier and more secure to sew it onto the fabric.

The product description indicates there are 2 pieces per pack, meaning one set (one stud and one socket).

The gunmetal finish is applied to the brass. With normal wear and care, it should be durable. Frequent rubbing or harsh cleaning methods could potentially affect the finish over extended periods.

Ensure both halves are securely sewn onto the fabric. Check if the fabric is too thin or stretchy; consider adding a small piece of interfacing behind the attachment points for reinforcement.

This can happen with thin fabrics. Ensure the thread is not pulled too tightly and consider using a stronger fabric or adding interfacing. Make sure the 'protective edges' are functioning as intended by sewing evenly.

Use a heavier-duty needle and a strong polyester thread. Pre-punching small holes in very thick materials might help, but be cautious not to damage the fabric.

Verify that the stud and socket are correctly aligned and fully engaged. If the issue persists, the sewing may not be secure enough, or the fabric may be deforming under pressure.
