This British Standard covers three types of eyebolt as follows:
- collar eyebolt, in the range 0.25 tonnes to 30 tonnes SWL;
- eyebolt with link, in the range 1.0 tonnes to 6.3 tonnes SWL;
- dynamo eyebolt, in the range 0.25 tonnes to 10.0 tonnes SWL.
Guidance on the selection of appropriate forgings and of SWL ratings when screwing eyebolts with imperial threads (see 4.1(b) and 4.1(c)) is given in appendix A.
Recommendations on the correct selection and safe use of eyebolts are given in the foreword and appendix B.
