This #3 self-piercing rolled rim grommet and small tooth washer set is made to support holes in a range of fabrics. It will puncture most fabrics without pre-punching a hole, while installing the grommet and washer in the same step. The grommet's sharpened edge delivers maximum piercing power while the small teeth lock in for exceptional hold. Made of heavy-gauge brass, these small but resilient parts can endure any type of climate, even those that encounter movement. Easily install the metal grommet and washer with the proper setting tools.
While ideal for curtains, drapery, and vinyl banners, they also work well in custom upholstery, outdoor awning, and marine jobs. Specific uses consist of awnings, seats, boat covers, flags and banners, luggage, privacy drapes, safety gear, signs and media, outdoor tents, and tarpaulins.
The inner diameter of the hole is 7/16". Comes standard in a pack of 500.
