No‑sew heavy duty snaps sized 15mm (5/8") for firm, heavyweight fabrics. The kit includes a setting tool and clear instructions so you can install caps, sockets, studs and posts without a press. Rust‑resistant finish offers durable performance on jackets, outerwear, bags and canvas projects. Use on two fabric layers or through a reinforced tab and test on a scrap to confirm the best placement before committing.
