HIKER BLACK SELF PIERCING GROMMETS Self-piercing grommets eliminate extra steps and save time, which saves you money! How? The tips of the barrels on each grommet are sharper and the material is more rigid, which allows the grommets to cut their own perfect sized holes every time. This eliminates the need to 'pre-cut' holes, saves labor hours and provides the framework for a quality grommet setting with every insertion. Having the grommets cut their own holes also eliminates the extra cost of purchasing and maintaining a separate hole-punch and allows significant savings ($1,600 on average), on electric presses because fewer moving parts are necessary. The benefits of self-piercing grommets at HIKER's industry low prices will make a positive impact on your company's bottom line.
