<br />2.0 USES
<br />The ITW Buildex TEKS® Self -drilling Fasteners described in
<br />this report are used in engineered or code -prescribed
<br />connections of cold -formed steel framing and of sheet steel
<br />sheathing to cold -formed steel framing.
<br />3.0 DESCRIPTION
<br />3.1 General:
<br />ITW Buildex TEKS® Self -drilling Fasteners are self -drilling
<br />tapping screws complying with the material, process, and
<br />performance requirements of ASTM C1513. The screws
<br />have either a hex washer head (HWH), an HWH with
<br />serrations, or a Phillips° (Type II) pan head. The screws are
<br />fully threaded with threads that comply with ASME B18.6.4,
<br />and the screws' drill points and flutes are proprietary and are
<br />designated as TEKS/1, TEKS/2, TEKS/3, TEKS/4,
<br />TEKS/4.5, TEKS/5.0 and TEKS/5. The screws have nominal
<br />sizes of No.10 (0.190 inch), No.12 (0.216 inch), and inch
<br />(0.250 inch), and lengths from inch to 4 inches (12.7 mm
<br />to 102 mm). See Figures 1 through 3 for depictions of the
<br />screws. Table 1 provides screw descriptions (size, tpi,
<br />length), nominal diameters, head style, head diameters,
<br />point styles, drilling capacity ranges, length of load -bearing
<br />area, minimum required protrusion lengths and coatings.
<br />Reissued July 2022
<br />This report is subject to renewal July 2024.
<br />3.2 Material:
<br />ITW Buildex TEKS° Self -drilling Fasteners are case-
<br />hardened from carbon steel conforming to ASTM A510,
<br />Grades 1018 to 1022, and are heat -treated and case-
<br />hardened to give them a hard outer surface necessary to cut
<br />internal threads in the joint material. Screws are coated with
<br />corrosion preventive coating identified as Climaseal°, or are
<br />plated with electrodeposited zinc (E-Zinc) complying with
<br />the minimum corrosion resistance requirements of ASTM
<br />F1941.
<br />3.3 Cold -formed Steel:
<br />Cold -formed steel material must comply with one of the
<br />ASTM specifications listed in Section A3.1 of AISI S100
<br />(Section A2.1 of AISI S100 for the 2015 and 2012 IBC) and
<br />have the minimum specified tensile strengths shown in the
<br />tables in this report.
<br />4.0 DESIGN AND INSTALLATION
<br />4.1 Design:
<br />4.1.1 General: Selection of screw length must be based
<br />on the thickness of the fastened steel members plus the
<br />minimum required protrusion past the back of the supporting
<br />steel. Point selection must be based on the drilling capacity
<br />of the screw. See Table 1 for minimum required protrusion
<br />lengths and drilling capacities.
<br />When tested for corrosion resistance in accordance with
<br />ASTM 13117, the screws meet the minimum requirement
<br />listed in ASTM F1941, as required by ASTM C1513, with no
<br />white corrosion after three hours and no red rust after 12
<br />hours.
<br />4.1.2 Prescriptive Design: ITW Buildex TEKS Self -drilling
<br />Fasteners described in Section 3.1 may be used where
<br />ASTM C1513 screws of the same size and head
<br />style/dimension are prescribed in the IRC and in the AISI
<br />standards referenced in IBC Section 2211 for steel -to -steel
<br />connections.
<br />4.1.3 Engineered Design: ITW Buildex TEKS° Self -
<br />drilling Fasteners may be used in engineered connections
<br />of cold -formed steel construction. Design of the connection
<br />must comply with Section J4 of AISI S100 (Section E4 of
<br />AISI S100 for the 2015 and 2012 IBC), using the nominal
<br />and allowable fastener tension and shear strength for the
<br />screws, shown in Table 5. Allowable connection strength for
<br />use in Allowable Strength Design (ASD) for pull-out,
<br />pullover, and shear (bearing) capacity for common sheet
<br />steel thicknesses are provided in Tables 2, 3, and 4,
