Common Nailing Errors
Wrong Angle
When a nail is driven into the bottom ange of the
wood I-Joist parallel to the glue lines, separation
of veneers can occur which substantially reduces
the design loads of the connection.
Nail Too Long
When using nails longer than MiTek’s recommended
nails, bottom ange splitting may occur. Also, this
can raise the wood I-Joist off the seat, resulting
in uneven surfaces and squeaky oors along with
reduced design load.
Left skew
Drive nails at angle
Right skew
Obround Holes:
For ease of nailing at a tight location;
always ll.
Dimple Holes:
Guide double shear nails into the joist
and header at a 30° to 45° angle
Use specified standard length common nails.
16d common and 10d common
nails are 3-1/2"and 3" long respectively.
