Interchangeable Dies for Snaps, Grommets, and Specialty Fasteners

The Pres-N-Snap® system is only as versatile as the dies you choose — and HooVer Products offers one of the most comprehensive die catalogs in the industry. With over 50 years of innovation, our interchangeable die sets allow you to quickly and accurately install a wide range of fasteners across canvas, vinyl, leather, and other materials.


From marine snaps to prong rings, from turn fasteners to self-piercing grommets, we engineer dies that perform flawlessly — whether you’re in the field or on the production line.

Built for Compatibility, Engineered for Performance

Pres-N-Snap dies are designed to install fasteners from leading brands like DOT™, Fasnap™, Stimpson™, YKK™, Surefas™, and more. Every die set is made from high-strength steel and features a quick-change design that allows users to swap dies in seconds using a twist-and-pull motion.


For optimal results, we always recommend matching the correct die set to the brand of fastener you’re using, as small differences in fastener design can affect installation quality.
