Flat-head brass eyelets with washers are durable fasteners meant to reinforce holes through leather, fabric, canvas and upholstery to help prevent fraying or tearing of any craft material. Flat-head brass eyelets with attached washers are made of rust-resistant brass, allowing for a polished finish while providing a firm hold with the washer. These eyelets commonly used in bags, belts, curtains, tarpaulins, sewing and craft projects for attachments.
