How much weight will an eye bolt hold?
For example, an eye bolt with a 1/4 inch shank can typically hold up to 600 pounds at a straight pull (no angle). However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the “straight pull” weight capacity).
What is the safe working load of a 1 eye hook?

How is eye bolt capacity calculated?
– Plain eyebolts must be engaged to within one-half turn from the eye end of the threads to get rated capacities given by the calculator. – Tapped holes for plain pattern (straight shank) eye bolts are threaded for the full length of eyebolt engagement….FORGED EYE BOLT CAPACITY AND STRENGTH.

What is the difference between a ring bolt and an eye bolt?
An eye bolt functions as a straight, stationary lifting point, while a hoist ring functions like an eye bolt, but with the added capability to swivel and pivot. Hoist rings are often used in place of an eye bolt when an overhead lift is angular or requires manipulation of the load.
How much weight will a 1/4 inch screw hold?
A single 1/4″ Grade 5 lag bolt, in a configuration like this, will fail at roughly 13,000 lbs. Even 1/8″ lag screws (well down into “numbered” screw sizes) will have a shear strength of over 3,000 pounds.
How much weight can a Grade 8 1 4 bolt hold?
The tensile strength of a grade 8 bolt is 150,000 pounds per square inch. Tensile strength is the maximum load in tension (stretching) that a part can carry without breaking.
How much weight can a 3 inch screw hold?
If you have room for a second or a third screw, just add more. Two screws can hold 160-200 pounds. Three screws can hold 240-300 pounds.
What’s the weight limit for an eye bolt?
In this case, the catalog working load limit of this 3/8th inch eye bolt is 1,550 pounds. At 15 degrees, the working load limit is reduced by 20% and the effective working load limit of the eye bolt becomes 1240 pounds, which is 80% of the original rated capacity.
How to adjust the load on eye bolts?
1.After the loads on the eye bolts have been calculated, select the proper size eye bolt for the job. For angular lifts, adjust working load as follows: Direction of Pull Adjusted Working Load 45 degrees 30% of rated working load 90 degrees 25% of rated working load
When does an eye bolt diminish in capacity?
As soon as a lift begins to occur at any other angle, referred to as angular lift, the rated capacity of the eye bolt begins to diminish. The greater the angle the more drastically the rated capacity is reduced. The chart below shows the impact the direction of pull has on rated capacity:
What should I know before using eye bolt assemblies?
Read, understand and follow information in diagrams and charts below before using eye bolt assemblies. Work Load Limit (Kgs.) Regular Nut and Shoulder Nut Eye Bolt-Installation for In-Line Loading. Always stand clear of load. Always lift load with steady, even pull – do not jerk. not at an angle.
