20.5.1 Working Load Limit
An eyebolt must have a working load limit at least equal to the total load that will be imposed on it and each pattern of eyebolt has its own limitations in this respect. It is therefore important to ensure that the correct type of eyebolt and maximum load rating are selected to suit the application. Details of the permissible applications of each type of eyebolt are given in this subsection. Further details of angular load ratings are given in 20.A1 APPENDIX - 1 EYE NUTS AND BOW NUTS.
It is sometimes preferable to have a permanent link inserted into the eye of collar eyebolts rather than use a shackle. Such eyebolts must still be rated and used only as collar eyebolts and under no circumstances must they be considered as ‘eyebolts with links’. (See section 20.5.4 Eyebolt with Link)
