We now offer Shoulder Eye Bolts at very competitive prices!! All sizes are in stock and ready to ship.

Shoulder Eye Bolts are used in vertical as well as angular lifts. The shoulder feature of these eyebolts provides more stability when lifting loads, keeping the shank of the eyebolt from rocking particularly when the load is heavy. Sierra Pacific Engineering and Products offers a large selection of eyebolts with shoulders which come in multiple sizes to suit our every customer’s needs. Each size is load-rated based on straight vertical lift. It is important to note that the rated capacity of eye bolts is substantially reduced when loading at an angle. Thus, loading must never be made at an angle that is greater than 45 degrees from the bolt center line. Otherwise, the rated capacity is reduced to ¼ of the eye bolt rating.

To ensure Stainless Steel eye bolt’s durability when exposed to the elements such as rigging or marine environment and for a high luster finish, each SPEP Stainless Steel shoulder eye bolt is passivated and  electropolished.

Now also available in 316SS material.
Other materials also available in stock, such as forged steel, 304SS and forged steel with zinc plated finish.
