This #4 grommet and tooth washer set is used to support holes in a range of fabrics. Forged from heavy-gauge brass, these compact yet resilient parts can stand up to any type of environment. The finish gives a matte black look and assists in abrasion resistance. The tooth washer features interlocking teeth for a stronger hold than a standard washer. Simply perforate a hole into the fabric then position the metal grommet and washer with the suitable setting tools.

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

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