(2) Screw pins must be:
(a) Fully engaged, with the shoulder in contact with the shackle body (see Figure 27, Typical Shackle Components).
(b) Rigged in a way that keeps the pin from unscrewing while in use.
(c) Secured from rotation or loosening if used for long-term installations.

(4) If the shackle is side loaded, reduce the rated load, according to the recommendations of the manufacturer or a qualified person (see Figure 28, Side Loading).
