* For two legged slings with angles greater than 90 degrees, use an intermediate
link such as a master link or bolt type shackle to collect the legs of the slings. The
intermediate link can be placed over the hook to provide an in-line load on the hook.
This approach must also be used when using slings with three or more legs.
• Never use an eye bolt if eye or shank is bent or elongated.
• Remove from service the hexagon body if internal threads
are corroded beyond 20% of the eye bolt or hoist hook
shank’s threaded engagement lengths.
• Hexagon body with nicks or gouges may be repaired by
grinding lengthwise.
• Inspect the spiral pin holes on the hoist hook, hexagon
body and eye bolt. At assembly, the spiral pin must engage
with a press fit.
