Machinery-style eye bolts are the most popular style of eye bolt we sell. They are designed to thread into a pre-tapped hole, although many of our customers choose to install them through a drilled hole and put a nut and washer on the end of the threaded shank. These eye bolts feature metric threads (see spec sheet at right for details). Made from forged carbon steel with a self-colored finish and shoulder pattern. Ratings are shown in both kg and lbs for easier reference. Their Working Load Limit is based on a safety factor of 5:1 for straight, in-line loading. Angular loading should be avoided as it reduces the Working Load Limit.
