You can learn more about hoist rings here. If you need to hold a load at extreme angles, consider using hoist rings instead. However, one key difference between eye bolts and hoist rings is that eye bolts are NOT designed to carry loads at extreme angles (45 degrees and above). Eye Bolts vs Hoist RingsĮye bolts have many handy applications. Some materials such as carbon steel are not safe to use in cold weather conditions, so it is important that you check with the bolt manufacturer to make sure your bolts are rated for safe use in the expected weather conditions. Eye Bolts In Cold Weatherįor the purpose of defining standards, “cold weather” is typically defined in this context as working conditions that are below 30 degrees F or -1 degrees C. When determining the maximum weight capacity for an eye bolt based on our table above, the “shank diameter” is the measurement of the diameter of the part of the bolt that has screw threads. Reduction In Maximum Weight Capacity By Angle Of Pull (Degrees)Ĥ6°+ = not safe to use an eye bolt consider a hoist ring instead How Are Eye Bolts Measured? Compare these percentages to the weight numbers shown in the table at the top of this page. Use the list below to help you determine how much of a load the bolt can hold depending on the angle of the pull.
However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the “straight pull” weight capacity). 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 just 15 degrees, the weight capacity is reduced by 20%. If the angle is less than 5 degrees, the weight capacity stays pretty much the same. The greater the angle, the less weight an eye bolt can hold. It’s very important to know that the degree of angle that the load is pulling from impacts how much weight the eye bolt can hold. Got Questions?

There are some additional things you need to consider to ensure the safety of your equipment and your staff, which we’ll share next. Please note that the above table should only be used as a general guide. In case you didn’t already know, an eye bolt’s “rated capacity” describes how heavy of a load a single eye bolt can support when the load is angled at 0 degrees through the eye bolt’s shank.Ĭheck with the bolt manufacturer to confirm exact weight capacity limits, but following is a helpful table that shows how much weight most eye bolts can hold.Įye Bolt Working Load Chart (Straight Pull, No Angle) Shank Diameter (in) Our support team often gets the question “how much weight can an eye bolt hold?” so we decided to provide an answer publicly for everyone to benefit from.
