In theory, plain pattern and shoulder pattern-lifting eyes are equally suitable for vertical lifts. When a shoulder pattern-lifting eye is properly seated in the receiving hole, the shoulder bears against the seat and reduces bending stress on the shank. Each type comes in different sizes and finishes.Ī regular nut eye bolt, also known as a plain pattern eye bolt, should not be used when applying angular loads as this procedure can bend or break them.Ī shoulder nut eye bolt can be used when applying angular loads, while keeping in mind the rated capacity is drastically reduced when loading at any angle. All three types come in two styles: plain and shoulder. The most common types of eye bolts used in industrial applications are: nut eye bolts, machinery eye bolts and screw eye bolts. These eyebolts are generally less expensive and ideal for use in low load applications.

Unrated eyebolts are, as the name implies, tools that have NOT been tested to ensure compliance against any governing standards. Rated eye bolts provide users with peace of mind that quality and stated rated lifting capacities are as assured as possible. Rated eye bolts have been independently laboratory certified to ensure with performance and mechanical property compliance against a governing standard such as ASME and ASTM. Bent eye bolts should only be used in light duty applications and should never be used to execute angular lifts.Įye bolts are available in two forms: rated and unrated. The ring can be drop forged (one single piece, the eye being entirely closed) or bent to form a loop. They are designed to have a rope or cable fed through the ring in order to lift objects. Eye bolts are threaded to structures such as wood or steel posts and often supported by a nut. One of the most commonly used pieces of hardware in material handling, an eye bolt has a simple design, consisting of a threaded shank with a ring/eye at one end. For this reason, selecting and using eye bolts correctly can make the difference between a safe work environment and one that puts people’s lives at risk. There are certain tools whose proper selection and use go beyond making your job faster and easier and actually affect workplace safety.Įye bolts are such tools. Selecting the right tool for the job can make a huge difference in productivity and quality of work.
