   Are these cranks? Do you have crank clearance?

   Don't these have a groove routed into the window? Mine all did and I just milled up some wood with a matching tongue, glued it in with trim glue, and put up the casing. No fasteners required on the extensions.

   You're looking to nail them to the window jamb.

   Don't.

   Use glue there as previously stated, then shim them and nail them to the RO, as you would a door jamb.

   I haven't installed Andersen windows in a few years so I need to ask you a few questions, to make sure that we're talking about the same window.  It'll help others here too.

   Are the Andersen jambs groved 5/4" stock?  Is there a piece of stop nailed to the jamb, extending slighty past the it on the inside?  Are the windows already permanently installed?

   Windows permanently installed.  Vinyl clad awnings.  Bought the andersen pre-made jamb extensions, 5/4 clear pine with tongue milled on one edge, fits into matching groove at window jamb.  Ext. jambs have pre-drilled holes through the width, presumably to nail or screw into window jamb.

   Excellent. That's the best, having the Andersen jamb extensions.  Using a 4 1/2" extension, I think I'd double drill them straight through for a shorter fastener.  You could use 8d finish nails and glue.  That would mean drilling the initial hole large enough to insert the driving tool, stopping at the proper depth.  Then drill a second, smaller hole completely through, one which makes a tight fit for the fastener.

   Another option, one I used when I made my own 3/4" pine jamb extensions for Andersen windows, was to pre-drill nail holes in the outside of the extension, angled toward the center.  Then I'd insert the 8d finish nails, place the extension tight against the stop and, using a long pin punch to get in next to the framing, drive the nails.

   I'd call around to find a long pin punch, to drive the nails.  It's a machinist's tool.  You could also try a long drill bit of the proper diameter. You may have to come up with your own driving tool but I'm sure you'll figure it out.

   same with any other brand with a wider that inch or so extension jamb.

    

   build the box first ... glue/shoot it together ...

   usually I'll case it too.

    

   don't care if it's traditional or picture framed ...

    

   then use a scrap as a guage ... and set the shims to the rough framing.

   leave them just a hair loose ...

    

   shoot the shims in where U are holding them.

    

   then ... slip the whole unit in as a prebuilt / precased deal.

    

   Just make sure there's enough "shimmage" on the bottom ... as wider rails make for drunk party guest seating.

   I find it's quicker for me to prebuild everything I can.

   used to have a pic on the old computer ... I'll see if it ever made it to the new one.

   This is a perfect job for Kreg pocket screws and glue...

   Carefully.

   Why didn't you get the window made to the specs needed to do the job right? Was there a salesman involved or was this a yard sale window?
   Andersen sells extension jambs.... Check with the lumber yard

   I actually bought 6" trim heads for exactly the same thing(they do make them), but ended up doing as Tashler said. Using Anderson extensions, I fit them into the grooves and trim nailed to rough opening.

   The GRK trimhead screws go up to 5" long
