We carry all Hiker self piercing grommets, including standard and long barrel grommets. The long barrel grommets (available for #2 hole size only) can be used for grommeting thick materials such as 10 mm thick coroplast. All Hiker grommets are made with high quality brass material. Available colors are brass, nickel-plated (over brass material) and chemical black (coated over brass material).
Self-piercing grommets eliminate extra steps and save time, thus save you money! The tip of the barrel on each grommet is sharper and the material is more rigid, which allows the grommet to cut its own perfect sized hole every time, therefore eliminates the need to punch holes separately. These self piercing grommets can even penetrate aluminum plates.
