**************************************************************************
Screws shall be [of the] [self-drilling self-tapping]type, size, and
location shown on the drawings. Screw penetration through joined materials
shall not be less than three exposed threads. Minimum spacings and edge
distances for screws shall be as specified in AISI SG02-1. Screws covered
by sheathing materials shall have low profile heads.

Anchors
**************************************************************************
NOTE: TI 809-07 provides suggested capacities of
expansion and power type anchors. Power driven
anchors can be used to attach tracks to structural
steel and concrete floors and foundations. Power
driven anchors will not be used to anchor shear
walls.
**************************************************************************
Anchors shall be of the type, size, and location shown on the drawings.

INSTALLATION
3.2.1
Tracks
Provide accurately aligned runners at top and bottom of partitions. Anchor
tracks as indicated in design calculations. Butt weld joints in tracks or
splice with stud inserts. Fasteners shall be at least 75 mm 3 inches from
the edge of concrete slabs.
3.2.2
Studs
Cut studs square and set with firm bearing against webs of top and bottom
tracks. Position studs vertically in tracks and space as indicated in
design. Do not splice studs. Provide at least two studs at jambs of doors
and other openings 600 mm 2 feet wide or larger. Provide jack studs over
openings, as necessary, to maintain indicated stud spacing. Provide
tripled studs at corners, positioned to receive interior and exterior
finishes. Fasten studs to top and bottom tracks by welding or screwing
both flanges to the tracks. Framed wall openings shall include headers and
supporting components as shown on the drawings. Headers shall be installed
in all openings that are larger than the stud spacing in a wall. In
curtain wall construction, provide for vertical movement where studs
connect to the structural frame. Provide horizontal bracing in accordance
with the design calculations and AISI SG-973, consisting of, as a minimum,
runner channel cut to fit between and welded to the studs or hot- or
cold-rolled steel channels inserted through cutouts in web of each stud and
secured to studs with welded clip angles. Bracing shall be not less than
the following:
