Eyebolts BS 4278

One of the most commonly used items of lifting accessories, but only those that are to the agreed standard should be used. The most common type found in the industry is the collar eyebolt, the collar eyebolt should have a thread that is run out and recessed under the collar, so that it can seat correctly against the load.

Where more than 1 eyebolt is to be used they should have the same SWL. The SWL of an eyebolt is for a vertical lift, if we have to use a pair of eyebolts they must be used along with shackles and a 2 legged sling or 2 independent slings but the SWl must be rated accordingly.

One of the things we have to be very careful with when using eyebolts is the selection of the SWL and the correct threads, if there is a mismatch of threads and the eyebolt is forced to mate a serious problem arises in that the eyebolt and load threads are now unfit for purpose. In such an instance the eyebolt will need to be quarantined and the appropriate procedures followed, and the department involved informed of the damage to the threaded hole(s).

Never lift any loads with the eyebolt if it is not fully seated onto the load. If for any reason the eyebolt is prevented from seating on the collar it is at risk from damage through

At no time use excessive force to secure the eyebolt that will not seat correctly with normal tightening. Over tightening can lead to stretching of the threaded shank resulting in hidden damage.
