AS 2317.1 – 2018 Lifting Points Part 1: Collared Eyebolts and Collared Eyenuts – Grade 4
This Standard was prepared by the Standards Australia Committee ME-025, Lifting Tackle, to supersede AS 2317—1998, Collared eyebolts.
This Standard is intended to promote the safety of collared eyebolts and collared eyenuts.
This edition includes the following technical changes from the superseded edition:
- (a) The inclusion of collared eyenuts.
- (b) A definition for a competent person has been included.
- (c) The definitions for working load have been amended.
- (d) The permitted types of screw threads have been extended to include a wider range of threads.
- (e) The range of nominal sizes for eyebolts has been extended. The working load limit (WLL) values and testing regimes have been altered to align more closely with ISO.
- (f) The requirements for testing of mechanical properties have been revised.
- (g) WLL marking requirements have been included.
- (h) The marked WLL is the transverse (or trunnion) loading.
This Standard is Part 1 of the AS 2317, Lifting points, series. When complete the series will include other parts that provide requirements for high tensile lifting points.
This standard covers:
Section 1 Scope and general
Section 2 Design and manufacture.
Section 3 Testing .
Section 4 Care and use of eyebolts and eyenuts
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.
