Eyelets are rings that are inserted into holes of other materials to reinforce the hole or shield objects from the sharp edges of the hole (in the case of metals). They are especially useful in cases where a hole is punched in hard material, leaving sharp edges, particularly when ropes, cords or electrical wires need to be passed through the hole.

Eyelets are sometimes called grommets, and the two terms are used interchangeably by some. Technically, grommets have larger flanges and diameters. The eyelet and grommet are both used in the apparel, shoe, candle and stationary industries.

Grommets or eyelets come in two parts: the trumpet portion and the washer portion. When using an eyelet, certain tools are required. First, some object must be able to punch through the material that needs a hole. Second, the trumpet and washer must be crimped together in order to secure the fabric. This is where a tool comes into play. A hammer can be used for lighter duty applications, however, for heavier grommets a special crimping tool is usually required. Self-piercing eyelets or grommets are specially designed to eliminate the need to pre-cut holes. This kind of grommet has a sharpened barrel, which allows them to cut their own holes as they are driven through fabric or other mediums, and are especially popular because they cut down on labor time and money spent on a hole-punch.

Eyelets can be composed of rubber, plastic, brass, stainless steel or a myriad of other substances. In certain circumstances, the material chosen can make a difference. For example, steel and aluminum degrades when brought into contact with water. To avoid this problem, one hundred percent stainless steel, nickel or brass is recommended.

Finally, as with any other product, grommets can fail. A loose or corroded crimp can result in breakage. To avoid this problem, there are specially designed grommets that have inner and outer teeth. These eyelets, once they are punched into fabric, are in permanently.
