This #1 grommet and tooth washer set is made to reinforce holes in a range of fabrics. Made of heavy-gauge brass, these small yet resilient pieces of hardware can withstand any type of setting. The tooth washer features interlocking teeth for a stronger hold than a standard washer. Just cut a hole into the fabric then install the metal grommet and washer with the right setting tools.

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

The hole's inner diameter is 9/32". 1 gross = 144 grommets and 144 washers (288 total pieces).

Install by hand with DOT Hand Tool and Die Set #223532.
