®
ITW BUILDEX TEKS SELF-DRILLING SCREWS
Structural steel framing supporting the steel deck panels
(such as bar joists and structural steel shapes) must be
manufactured from code-compliant steel having minimum
strength requirements of ASTM A36, ASTM A572 Grade
50, or ASTM A992-11(2015).

2.0 USES
®
The ITW Buildex TEKS self-drilling tapping fasteners
(screws) are used in connections of bare and concrete
filled steel deck diaphragms. The #12-24 TEKS/4,
TEKS/4.5, and TEKS/5 are used to connect steel deck
panels to supporting framing. The #10-16 TEKS/1 &
TEKS/3 and #12-14 TEKS/1 & TEKS/3 are used to
connect steel deck panel sidelaps.
3.0 DESCRIPTION
3.1 TEKS:
As recognized in ESR-1976, the TEKS fasteners are case
hardened from carbon steel conforming to ASTM A510,
Grade 1018 to 1022; have hex washer heads (HWH);
comply with the material, process, and performance
requirements of ASTM C1513-13; have threads complying
with ASME B18.6.4; have proprietary drill points and flutes
designated as TEKS/1, TEKS/2, TEKS/3, TEKS/4,
TEKS/4.5, and TEKS/5; and are coated with a corrosion
®
preventive coating identified as Climaseal , which
complies with the minimum corrosion resistance
requirements of ASTM F1941-15. See Table 1 for TEKS
Fastener Selector Guide.
Concrete fill must be either normal weight [(145 lb/ft )
3
3
3
(2323 kg/m )] or lightweight [(110 lb/ft ) (1762 kg/m )]
specified in accordance with the applicable code and have
a minimum 28-day compressive strength of 3,000 psi
(20.7 MPa). Concrete reinforcement must comply with the
applicable code.
4.0 DESIGN AND INSTALLATION
4.1 Design:
For symbols and definitions, see the American Iron and
Steel Institute’s North American Standard for the Design of
Profiled Steel Diaphragm Panels (AISI S310-13).
4.1.1 Diaphragm Shear and Stiffness by Calculations:
Diaphragm shear and stiffness by calculations may be
determined in accordance with AISI S310-13 while using
Tables 1 through 9 and the following safety and resistance
factors.

4.1.2 Diaphragm Shear and Stiffness by Tabulated
Values: Diaphragm shear and stiffness may be
determined per Tables 10 through 21.
4.1.3 Uplift/Tension:
For
designs
considering
uplift/tension forces, the #12-24 TEKS pullout and pullover
strength, when installed through steel decks and into
support steel, are provided in Tables 23 and 24, while the
tension strength of the #12-24 TEKS alone are provided in
Table 25.
4.1.4 Shear: For information regarding the TEKS shear
strength installed in different gages of steel and installed
through different gages of steel and into supports, see
ESR-1976.
4.2 Installation:
Steel deck panel ends must overlap a minimum of 2 inches
(51 mm). End lap and corner lap conditions of two- and
four-deck layers must be snug and tight to one another and
the supporting steel frame, prior to frame fastener
attachment.
The TEKS at supports perpendicular to the deck panels
spans must be spaced per the layout in Figure 1. For
spans greater than 5 feet, the TEKS at perimeter supports
and sidelaps must not exceed 36 inches on center. The
TEKS must penetrate through the supporting steel with a
minimum three threads protruding past the back side of the
support steel.
5.0 CONDITIONS OF USE
Steel deck diaphragms comprised of steel deck panels
attached to steel supports with TEKS as described in this
report, comply with, or are suitable alternatives to what is
specified in, those codes listed in Section 1.0 of this report,
subject to the following conditions:
5.1 The fasteners are manufactured, identified and
installed in accordance with this report, the
manufacturer's instructions and the approved plans. If
there is a conflict, this report governs.
5.2 The base metal thickness for deck panels delivered to
the jobsite must be at least 95 percent of the design
metal thickness.
5.3 The minimum loads of IBC Section 1607 must be
considered by the design professional based on the
specific occupancy or use, as applicable.
5.4 Special inspection shall comply with IBC Chapter 17.
5.5 Calculations and details demonstrating that the loads
applied to the deck panels comply with this report
must be submitted to the code official for approval.
Calculations and drawings, must be prepared, signed
and sealed by a registered design professional where
required by the statutes of the jurisdiction in which the
project is to be constructed.
5.6 The Diaphragm Flexibility Limitations in Table 22
must be considered.
5.7 Concrete-filled sections must not be used to support
loads that are predominantly vibratory, such as those
for operation of heavy machinery, reciprocating
motors and moving loads.
5.8 When the steel deck panels are used as roof decks,
the panels must be covered with an approved codecomplying roof covering.

FIGURE 1—TEKS SUPPORT FASTENER LAYOUT
Notes:
1. For nestable-type decks, support fasteners on the sides are installed through both connecting steel deck panels and into the supporting framing.
2. For interlocking-type decks, equal numbers of support fasteners on the sides must be installed on each side of the sidelap and into supporting
framing.

Diaphragms are to be investigated regarding their flexibility and recommended span-depth limitations.
Diaphragms supporting masonry or concrete walls are to have their deflections limited to the following amount:

Δwall =

fc

H 2 fc
0.01 Et
Unsupported height of wall in feet.
Thickness of wall in inches.
Modulus of elasticity of wall material for deflection determination in pounds per square inch.
Allowable compression strength of wall material in flexure in pounds per square inch.
For concrete, fc = 0.45 f’c. For masonry, fc = Fb = 0.33 f’m.
The total deflection Δ of the diaphragm may be computed from the equation: Δ = Δf + Δw
3
where:
Δf
Δw
=

Flexural deflection of the diaphragm determined in the same manner as the deflection of beams
The web deflection may be determined by the equation:
Δw =
q ave L F

where:
L

qave =
F
=
4
Distance in feet between vertical resisting element (such as shear wall) and the point to which the deflection is to be determined.
Average shear in diaphragm in pounds per foot over length L.
Flexibility factor: The average micro-inches a diaphragm web will deflect in a span of 1 foot under a shear of 1 pound per foot.
When applying these limitations to cantilevered diaphragms, the allowable span-depth ratio will be half that shown.

Notes for Tables 23-25
1
For tension connections, the lower of the fastener pull-out (Table 23), pullover (Table 24), and fastener tension strength (Table 25) must be used for
design.
2
For ASD, divide the tabulated values by 3.0.
3
For LRFD, multiply the tabulated values by 0.5.
4
For Fu = 58 ksi, multiply values by 1.29; for Fu = 65 ksi, multiply values by 1.44.
