3 MECHANICAL CHARACTERISTICS & MOUNTING
The central threaded recess accepts a metric M3 threaded bolt. The recess is approximately 4 mm deep (4.32 +/-
0.08 mm). The following drawings show example geometries for mounting hardware in case you wish to design
your own custom mount. Figure 5 shows mounting geometry for a mount formed from steel sheet metal that is 1.15
mm thick. Figure 7 shows similar mounting geometry for mount formed from aluminum sheet metal that is 1.25 mm
thick. Use caution when tightening the mounting bolt. Tightening the mounting bolt can cause the mount to pull
tight directly against the metal insert, not against the plastic housing, which would tend to pull the insert out of the
plastic. Figure 6 shows the dimensions of our GPS 18x Flush Mount, part number 010-10453-00.
