Shoulder bolts (also known as stripper bolts) feature an unthreaded shoulder that allows for smooth rotation or sliding of adjacent parts, making them ideal for use in linkages, pivots, and pulleys.

Eye bolts are designed with a looped head to secure cables, ropes, or chains for lifting and rigging applications. Ensure you choose shoulder-pattern eye bolts for angular load lifting to prevent bending.

U-bolts are measured by the inner diameter (width between the legs), the length of the legs, and the thread size. They are commonly used to clamp pipes, tubes, or round bar configurations to flat surfaces.

Stud bolts provide stronger clamping force, more uniform tension distribution, and are easier to assemble/disassemble in heavy duty industrial connections, such as flange joints.

J-bolts are hook-shaped fasteners typically embedded in concrete to anchor structural supports, while carriage bolts feature a smooth dome head and a square neck underneath to lock into wood or metal joints without spinning.
