Drywall Screws in Joist Hangars

How many do you want?

R104.9 Approved materials and equipment. Materials,
equipment and devices approved by the building official shall
be constructed and installed in accordance with such
approval

R106.1.2 Manufacturer’s installation instructions.
Manufacturer’s installation instructions, as required by
this code, shall be available on the job site at the time of
inspection.

R502.6.2 Joist framing. Joists framing into the side of a
wood girder shall be supported by approved framing
anchors or on ledger strips not less than nominal 2 inches
by 2 inches (51 mm by 51 mm).
 
Looks like the hanger is fastened to the web of an i-joist. Don’t think the mfgr allows that.
 
R106.1.2 in regards to the SST hanger, drywall screws would not be permitted but SST screws would. So the hanger would not be installed correctly per manufactures instructions. I believe the correct hanger is being used for a 1.5 width framing lumber unless the plans state otherwise. GP and TJI allow both USP and Simpson hanger usage with this type LVL beam.
 
Those don't look to be the correct Simpson hard nails for the hanger, appear to be 2 different types of nails as well.
