An anchor that combines looks and toughness, the DOT Rolled Rim Grommet with Spur Washer #4 in government black brass gives outdoor and marine fabrics a strong, long-lasting edge. Made for the demands of patio, tent, awning, and marine hardware, these #4 grommets feature a rolled rim for durability and a spur washer with interlocking teeth for a secure, rust-resistant hold--far stronger than standard washers. The heavy-duty brass construction and matte black finish resist corrosion while blending into upscale outdoor decor. Each 1-gross pack includes 144 grommets and 144 washers, designed to reinforce 9/16-inch holes in fabric, leather, and upholstery for reliable reinforcement with a clean, finished look. Built to meet military and government specifications, these grommets are the trusted upgrade for industrial, marine, or sophisticated backyard projects.
