There are several different types of eye bolts, including standard, shoulder, and swivel. Standard eye bolts have a smooth shank and a loop that is perpendicular to the shaft. Shoulder eye bolts have a shoulder or collar below the loop, which helps to distribute the load more evenly. Swivel eye bolts have a loop that is mounted on a ball bearing, which allows it to rotate freely.
Eye bolts are made from a variety of materials, including steel, stainless steel, and brass. They are available in a range of sizes and thread pitches to suit different types of applications and loads. It is important to choose the appropriate size and material for the specific application, as the eye bolt must be strong enough to support the load without breaking or deforming.
