An eye bolt is a bolt with a loop at one end and used to firmly attach a securing eye to a structure, so that ropes ,chain or cables

may then be tied to its loop. Some eye bolts also feature the ability to pivot or swivel.

As eye bolts are typically used to attach ropes, string or chains to objects, Many people string wire from eye bolts on the back of picture frames, for instance, to allow them to rest on hooks or nails on a wall.

Eye bolt thread sizes are available in standard inches and metric millimeters. Common sizes in standard measurements range from ¼ inch all the way to 2 ¼ inches in diameter. Common sizes in metric measurements range from 6 mm to 64 mm in diameter, and are available in 1 mm increments.

Several different types of eye bolts are available in a number of materials. Inspect eye bolts regularly to check for wear and effectiveness. Eye bolts are manufactured out of several materials including aluminum, bronze, hardened and stainless steels, brass and titanium.

Some common types of eye bolts are forged eye bolts, screw eye bolts and shoulder eye bolts. Each type of eye bolt has its practical applications. Forged eye bolts offer higher load ratings than most eye bolts. Screw eye bolts are often used for lifting and rigging.The shoulder feature provides more stability to the base of the eye and therefore, makes it the recommended choice for angular loading. 

All of these basic types that Qingdao Sail Rigging offers are manufactured in the drop forged process to ensure greater strength and have a hot dip galvanized finish.

1.Use plain or regular eye bolts (non-shoulder) or ring bolts for vertical loading only. Angle loading on non-shoulder bolts will bend or break them.

2.Use shoulder eye bolts for vertical or angle loading. Be aware that lifting eye bolts at an angle reduces the safe load.

3.Follow the manufacturer's recommended method for angle loading.

How should you use eye bolts safely?

Orient the eye bolt in line with the slings. If the load is applied sideways, the eye bolt may bend. Pack washers between the shoulder and the load surface to ensure that the eye bolt firmly contacts the surface. Ensure that the nut is properly torqued.

Engage at least 90% of threads in a receiving hole when using shims or washers.

Attach only one sling leg to each eye bolt.

1.Inspect and clean the eye bolt threads and the hole.

2.Screw the eye bolt on all the way down and properly seat.

3.Ensure the tapped hole for a screw eye bolt (body bolts) has a minimum depth of one-and-a-half times the bolt diameter.

4.Install the shoulder at right angles to the axis of the hole. The shoulder should be in full contact with the surface of the object being lifted.

5.Use a spreader bar with regular (non-shoulder) eye bolts to keep the lift angle at 90° to the horizontal.

*Use eye bolts at a horizontal angle greater than 45°. Sling strength at 45° is 71% of vertical sling capacity. Eye bolt strength at 45° horizontal angle drops down to 30% of vertical lifting capacity.

*Use a swivel hoist ring for angled lifts. The swivel hoist ring will adjust to any sling angle by rotating around the bolt and the hoisting eye pivots 180°.
