Measure length for locking bolt and insert locking bolt
Measure the length for the locking bolt with the Depth
Gauge for Locking Bolts (357.791). The length of the locking
bolt is determined by adding at least 2, but not more than
4 mm to the length read from the depth gauge.
Insert the locking bolt using the hexagonal screwdriver.

Insert end cap
The use of the turquoise End Cap for Locking Screw
(451.896) is mandatory.
It fulfills two functions: It prevents
bone ingrowth into the nail and blocks the distal Locking
Screw
6.0 mm thus providing a stable angle.
Remove the insertion instruments.
Using the hexagonal screwdriver, align the end cap with the
nail axis and fix it by means of the holding sleeve. To minimise
the chance of cross-threading, turn the end cap counterclock-
wise until the thread of the end cap aligns with that of the
nail. By turning clockwise, completely screw the end cap into
the nail, so that the locking screw is fixed. The last turns will
offer some resistance caused by a groove in the thread which
prevents the screw from loosening. Tighten the end cap
firmly.
Alternative
The end cap can also be inserted after step 14 (page 14).
