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. Use shoulder eye bolts for vertical or angle loading. Be aware that lifting eye bolts at an angle reduces the safe load.
What is a lifting eye bolt?
Shoulder Pattern Lifting Eye Bolt
Shoulder patterned lifting eye bolts, often called machinery eye bolts, collared lifting eye bolts or lifting eyes, feature a shoulder under the eye that provides greater stability for angular lifts by reducing stress on the shank.
What is a shoulder eye bolt?
These eye bolts are designed with a shoulder at the point where the eye and the shank come together . This shoulder design reduces bending stresses on the shank and allows the eye bolt to be used for angular lifting if the shoulder is properly seated in the load.
How does an eye bolt work?
Eye bolts are threaded to structures such as wood or steel posts and often supported by a nut. They are designed to have a rope or cable fed through the ring in order to lift objects . The ring can be drop forged (one single piece, the eye being entirely closed) or bent to form a loop.
What is the difference between a ring bolt and an eye bolt?
Unlike eye bolts, which remain stationary for the duration of a lift, hoist rings can pivot 180° and/ or swivel 360° from the screw's axis to accommodate load movement. Unlike eye bolts, the WLL of a swivel hoist ring is not impacted by angular lifts.
Can you use eye bolts for swings?
The hooks, screws eyes or eye bolts should be installed 2 to 4 inches wider than the swing's length — i.e., for a 48-inch swing, space the hangers 50 to 52 inches apart. This ensures even weight distribution and prevents the chains from rubbing against the swing.
How is eye bolt capacity calculated?
| Shank Diameter (in) Weight Capacity (lbs) | 3/4 5,200 | 7/8 7,200 | 1 10,000 | 1-1/4 15,000 |
|---|
What is a ring bolt used for?
An eyebolt is a mechanical fastener with a threaded shaft and a head forming a ring. Eyebolts are used to attach an eye to a structure , through which rope, cable or shackles can be secured.
How do you bolt an eye in the ceiling?
Screw the eye bolt into the pilot hole by hand. If the hook is difficult to turn, insert the shaft of a screwdriver into the eye of the hook . Use the handle and shaft of the screwdriver as a handle to turn the eye bolt. Turn the hook until the threaded portion is completely within the ceiling.
How do I choose an eye bolt?
Size Designation of Eye Bolts
The 1⁄2” measurement references the diameter of the shank. The 6” measurement refers to the length of the shank. The larger the diameter of the shank, the larger the working load limit. A longer shank length allows you to go through thicker objects.
How do you hang a hammock with eye bolts?
Drill 3/8 -inch pilot holes into both anchor points. Screw in heavy-duty eye-bolts that are long enough to have at least 2 inches screwed into the solid wood joists. Attach chain, ropes, or cords to the end-loops of the hammock to get your desired length and sag.
Can I hang a swing from my ceiling?
If you have a finished ceiling, you will need to remove some of the trim or paneling on the ceiling to determine the joist depth. To hang a swing from a single joist or beam, it needs to be a 2 x 8 joist or 4 x 4 beam.
How long should a beam be for 3 swings?
If you want 3 use a 12 ft beam . Your swing hangers will be 18 or 20 inches apart, and you want 20 plus inches between swings. 3 of 3 found this helpful.
