51-00-12 Single Wire Safe Tying
Insert the wire through each part consecutively in the direction that will prevent the part from
loosening. Draw the wire tightly around each bend and twist the ends into a tight pigtail close to one
of the safe tied parts. Cut the pigtail square, leaving a minimum of three twists. Bend the pigtail over
against the part being safe tied to prevent snagging. You should not use safety wire longer than 24
inches for single wiring three or more parts as a group.

51-00-13 Double Wire Safety Wiring By Hand
Pull the wire through the first bolt. Bend one end of the wire around the head of bolt #1 toward bolt
#2, in a direction such that a pull on the twisted wire toward bolt #2 would cause bolt #1 to tighten.
Twist the outer wire under the other wire close to bolt #1. Continue twisting the wire clockwise,
keeping the strands wide apart to ensure a tight even twist. When the twisted pair reaches bolt #2
without slack, insert the wire in the bolt hole in a direction so that bolt #2 cannot loosen without
pulling bolt #1 tight. Bend the free wire around the head of bolt #2, and twist the wires counter
clockwise. Continue twisting counter clockwise beyond the bolt to form a pigtail. Cut the pigtail
square, leaving a minimum of three twists. Bend the pigtail over against the part being safe tied, to
prevent snagging.
