(1) Steel maillons are stamped with a "Working Load Limit" (WLL) corresponding to 20% of their breaking strength (BL).

(2) The WLL is the maximum load the manufacturer guarantees will not deform the maillons, allowing opening of the screw closure with fingers.

(3) When using steel maillons, double-check and triple-check that they are screwed shut properly as part of every pre-flight check.
