AS 2317.1:2018 PDF
This Standard specifies requirements for Grade 4 forged collared eyebolts and collared eyenuts used for lifting.
Eyebolts are used in lifting, tensioning and staying systems to connect the systems to a tapped hole or through a hole into a nut. Eyenuts are used in lifting, tensioning and staying systems to connect to a threaded stud.
In any lifting, tensioning or staying system, the working load of each component needs to take account of the conditions (such as the classification of load application as specified by AS 1418.1) and be compatible with any loads inherent in and applied to the system, and each component should readily connect with each adjacent component. Therefore, it is important that components of lifting, tensioning or staying systems be quickly and positively identified in service for size, lifting capacity and quality grade.
Only one grade of fitting is detailed in this Standard because the materials into which the eyebolts are fitted may have low mechanical strength properties. The material specified in this Standard is equivalent to the quality Grade 4 (previously referred to as Grade M) materials used for the manufacture of other types of lifting components. Eyebolts and eyenuts of a quality grade material greater than 4 are not excluded from use, provided they are interfaced with compatible materials and meet the required performance criteria.
