Important Eyebolt Information

Working Load Limit - WLLs are applicable when the stated load is applied along the vertical axis of the eyebolt.

Safe Working Load - SWLs are applicable when used for specific lifting configurations under different working conditions.

Safety Factor - Both metric & imperial eyebolts have a safety factor of 6:1.

All thread forms must be checked prior to installation.

Thread Selection - Extreme care must be exercised in ensuring that an eyebolt's thread form & the thread form in the corresponding hole or nut is the same.

Collar & Face Seating - In order to achieve the WLLs shown, the collar face & the contacting face must be flat, smooth, & must be perpendicular to the threaded hole.

Eyebolt Maintenance - When eyebolts are reused, it is strongly recommended that they are critically examined periodically for wear on the thread form or for any bruising.

Correct Fitting of Eyebolt Pairs - When using eyebolts in pairs, it is essential that care be taken to properly align them. Eyebolts must not be forced into alignment as over stressing will reduce their safe working load.

Should misalignment occur at the first fitting, the following actions should be taken:

machine the underside of the eyebolt by no more than half the pitch of the thread; or
fit a steel shim with a thickness of no more than half the pitch of the thread.
