DOT Grommet with Tooth Washer #1 offers strong hole reinforcement through durable brass construction designed to resist corrosion and endure high-stress environments. With a 9/32 inch inner hole diameter and a heavy-gauge design, this hardware set features interlocking teeth on the tooth washer for a secure grip, especially effective on woven materials. Packaged as 1 gross containing 144 grommets and 144 washers, it suits a variety of indoor and outdoor uses such as banners, marine applications, upholstery, tents, tarps, covers, and signs. Installation requires cutting a hole in the material and using proper setting tools, making it ideal for reinforcing holes in fabrics subjected to frequent movement or strain.
