An eye bolt is a bolt with a loop at one end. They are used to firmly attach a securing eye to a structure, so that ropes or cables may then be tied to it. Wire eye bolts (also referred to as bent or turned eye bolts) are used for light duty applications, and should not be used for angular loads. Drop forged eye bolts are significantly stronger than wire eyes and are available in larger sizes. These bolts should not be used for angular loads. Drop forged machinery eye bolts are fully threaded. Machinery eye bolts without a shoulder should not be used for angular loads.
