Hex bolts have hexagonal heads and machine threads for use with a nut or in a tapped hole. Also known as hex cap screws or machine bolts.
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.
U-bolt is a bolt bent into the shape of the letter “u.” It's a curved bolt that features threads on each end. Because the bolt is curved, it fits nicely around pipes or tubing.
An anchor bolt is a heavy-duty fastener that’s used to connect objects to concrete. Steel poles, for example, are often mounted onto concrete surfaces using anchor bolts. The anchor bolts are driven through the base of the pole and into the concrete itself. Thanks to the unique design of anchor bolts, the pole remains stable and secure.
