This #4 grommet and tooth washer pair is designed to support holes in a range of fabrics. Made from heavy-gauge brass, these small yet resilient parts can withstand any kind of climate. The nickel plating gives added abrasion resistance and a silver finish. The tooth washer features interlocking teeth for a stronger hold than a plain washer. Simply perforate a hole into the fabric then install the metal grommet and washer with the proper setting tools.

While great for drapery, curtains, and vinyl banners, they also operate well in marine, custom upholstery, and outdoor awning jobs. Specific applications include signs and media, awnings, seating, boat covers, flags and banners, luggage, privacy drapes, safety gear, outdoor tents, and tarps.

The hole's inner diameter is 1/2". 1 gross = 144 grommets and 144 washers (288 total pieces).
