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. However you use them, just know these eye bolts are made in the U.S.A. from drop forged Type 316 stainless steel. This makes them ideal for use on boats, in marine environments and food processing plants. 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.
