I used eye bolts through a beam for 2 swing’s over 30 years ago. Big washers on top and nylock nuts so they would not back off. Now my grand kids use the swings and they still work fine.

Can you use eye bolts for swings?

Shipping calculated at checkout. Most arborists agree that the best way to hang your tree swing is to insert a stainless steel eye bolt into the branch. This will ensure that the rope is not rubbing the branch and potentially causing damage to the tree.

How much weight will eye bolts hold?

Quote from Youtube video: You could do it this old-fashioned way by using the screwdriver as a lever. But there's a better. Way. After drilling a pilot hole.

What are eye bolts used for?

Eye bolts can be used as a connection point for rigging, anchoring, pulling, pushing, or hoisting applications. Although eye bolts are commonly used in industrial applications, they’re also commonly misunderstood or used incorrectly.

How much weight can a M12 eye bolt take?

Never exceed Work Load Limits specified in Tables 1 & 2. Never use regular nut eye bolts for angular lifts.

Metric Size Work Load Limit (Kgs.)
M12 1,000
M16 1,800
M20 2,500

What is the difference between a ring bolt and an eye bolt?

The eye bolt has a single ring forged to the top of the shank, while the ring bolt has an additional ring that articulates around this first forged ring. This means that the eye bolt is designed to accommodate forces from straight above or below, while the ring bolt can handle forces coming from an angle.

What can I use instead of an eye bolt?

Like eye bolts, hoist rings can be used as a connection point for rigging, anchoring, pulling, or hoisting applications. They are often used to lift items like: Plates of steel.

How do you secure an eye bolt?

Quote from the video:
Quote from Youtube video: The eye bolts are threaded to UNC standard and as such the hole needs to be tapped accordingly to ensure the shoulder will be firmly seated against the object to be lifted.

How do you calculate load carrying capacity of a bolt?

Tensile strength is the maximum tension-applied load the fastener can support prior to fracture. The tensile load a fastener can withstand is determined by the formula P = St x As.

How much force can a bolt take?

Steel bolts are graded according to newtons per millimeter squared for bolt tensile strength as compared to yield strength. For example, a steel bolt with a rating of 5.5 will provide roughly 500 newtons/mm2 of bolt tensile strength and approximately 400 newtons/mm2 of yield strength.

How do I know what size bolt I need?

What is the strongest bolt?

Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.

How can you tell the strength of a bolt?

You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.

What grade bolt do I need?

Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt. For most home and automotive applications, you won’t need anything more than a grade 8 bolt strength or metric class 10.9.
