Confused By Eyebolt Standards? Let’s clear it up.

In 1960, when ANSI first published the B18.15 standard on forged eyebolts, they stated “that it would be impossible to develop an ANSI standard which would agree with even a small percentage of the standard products (eyebolts) being produced.” This forced them to attempt to come as close as possible to an average value for forged eyebolts.

eyebolts image blog .jpegCurrently there are two standards that cover forged eyebolts; ANSI/ASME B18.15 “Forged Eyebolts” and ANSI/ASME B30.26 – 2015 “Hardware” (if you are wondering which OSHA regulation covers eyebolts capacities, well OSHA does not address them). Most companies will adopt to follow ANSI/ASME standards to any OSHA requirements that may exist. However, in the case of eyebolts this can cause some issues, because there are two conflicting ANSI/ASME standards.

  • B18.15 has a capacity table with reductions for 30, 60, and 90 degreeangular loads.
  • B30.26 does not list eyebolt capacities, but they do state that “each eyebolt shallbe marked to show size or rated load” and B0.26 requires angular load reductions.

So if we use the guidance from B18.15 for eyebolts used at 90 degrees they will be significantly higher in value than what is recommended in B30.26. So which standard should you follow then?

The safest way to determine the eyebolt capacity is to ask the eyebolt manufacturer, and this should always be the first choice.

But if the manufacturer states that you cannot use their eyebolt at 60 degrees and you decide to follow the ANSI standards instead and the eyebolts fail then you will be considered at fault because you didn’t follow the manufacturer’s instructions. We had to get real there for a second.
