Our self-piercing grommets and fasteners are made from high-quality solid brass. Solid brass grommets will not rust! Brass will not stick to a magnet. If your existing grommets stick to a magnet then they are only brass plated steel and they will rust. Stock finishes available in Antique Brass, Brass, Nickel, or Black Oxide.
These self-piercing grommets function together with our specially designed setting dies. This combination enables the grommet setting machine to pierce the material and set a grommet in a single action without pre-punching a hole. Excellent results are obtained on many materials including vinyl banners.
Choosing a Grommet Size:
If you are using a grommet press for thin applications, such as banners, posters and laminate, then standard self-piercing grommets are needed.
If you are using a grommet press for thicker applications, such as foam core or corrugated plastic Coreplast boards, then you will need long neck self-piercing grommets where the length under the flange is bigger.
If you will be doing both thin and thick materials, it is recommended that you get both kinds of grommets. The reason for this is that if you use the long neck grommets on the thinner materials, the neck is too long to roll over onto the washer and you will be left with a grommet that spins in place.
