20.5.5 Collar Eyebolt

Before the introduction of the eyebolt with link, the collar eyebolt was considered as the general purpose type. It is however more limited in its use than the eyebolt with link. Although the SWL in axial loading is greater than that of the eyebolt with link, it is markedly reduced in angular loading and alignment of the eye is important.

Collar eyebolts may be used up to the marked SWL provided that the load is in line with the axis the SWL is reduced by the appropriate factors. In non-axial loading the load should be applied within ±5° of the plane of the eye. (See Figure 20.5.5-1 )

Collar eyebolts are not suitable for direct connection to a hook; a shackle is normally used as an intermediate link. For guidance on the selection and use of shackles see SECTION 19 of this code.

Collar eyebolts may be used for trunnion lifting.
