Blender 2.8 Modeling Excavator : Finish the Arm

Here is the next part for modeling an excavator with Blender 2.8 - in this video I finish modeling the arm and create a connection part for the syringe to lift it.

I use my fast carve addon again for boolean operations and for creating primitive shapes.

Fast carve suggestion:
I've made some simple one slot screw heads, by making a rectangle, extruding,
make a loop and delete bottom part of rectangular box then boolean operation.

Is it possible to make a phillips head screw head with fast carve add-on?
