holes for these anti-rotation pins. Then, reinstall the sex bolt head,
install some Threadlock
from the capsule on the sex bolt base plate threads and screw in the base plate
Next, install the roll pin bushings into the holes previously prepared for them and install the long
(2”) roll pins into the strike plate.
Do not use the shorter roll pins delivered with the
Magnalock
. Then, place the flathead strike mounting screw through its plastic bushing and
through the strike plate. On the other side of the plate, push three rubber washers and one
steel washer onto the strike mounting screw as shown in Figure 1. To screw this complete
assembly into the MXD sexbolt, you have to follow a
special procedure
to prevent the female
threaded shaft in the MXD sexbolt from spinning. First,
apply Threadlock
onto the strike
mounting screw threads and then Insert the screw into the MXD sexbolt and turn it a couple of
times to catch a few threads. Then pull on the strike plate so that the spring loaded female
threaded shaft in the sexbolt comes out. Hold it out against its spring pressure by rotating the
strike a bit so that the roll pins no longer go into their bushings but hit the permanent magnet
bracket. This will allow you to get a vise grip onto the female threaded shaft in the MXD sexbolt.
Turn the strike mounting screw a couple of more turns and then re-rotate the strike so that its
roll pins again insert into their bushings. Then finish tightening the strike mounting screw but
don’t over-tighten so that the rubber washers become compressed.

2.5 MOUNTING THE SUB-PLATE
Using the template, you should have previously marked and drilled mounting holes for the sub-
plate. You have been supplied with an array of fasteners and because doors and stops will
vary, the selection of fasteners will vary from installation to installation. Note the following
points, however: Machine screws into blind nuts are much stronger than sheet metal screws so
they should be used for primary mounting with the sheet metal screws in a “helping” role.
Review the section on magnet mounting in your Magnalock manual to see how to mount and
collapse the blind nuts. Also, note that the hole preparation on the sub-plate allows for the use
of flat head or socket cap screws without the need for any washers.
