2 Dril-Flex Structural Self-Drilling Fasteners Offers virtual immunity to hydrogen-assisted stress corrosion cracking for maximum performance in the field Dril-Flex fasteners are specially designed and processed to help prevent hydrogen-induced brittle failures. Each fastener undergoes the unique Flex Technology dual-hardening process to ensure the optimal combination of ductility and hardness required for maximum performance in the field. Testing of this product, in accordance with ASTM standards, has proven that Dril-Flex fasteners provide the same resistance to hydrogen-assisted cracking (HAC) as a Grade fastener. Unique Hardening and Finishing Processes Provide High Performance Hydrogen-Assisted Stress Corrosion Cracking (HASCC) refers to a time-delayed failure that is aggravated or accelerated by hydrogen generated in the application. This is most often encountered and associated with dissimilar metal applications through the galvanic corrosion process. Most self-drilling fasteners, including 40 fasteners, are case or similarly hardened, which provides the necessary hardness for drilling and tapping, but leaves the screws vulnerable to HASCC due to their high surface or core hardness. Dril-Flex fasteners offer the unique Flex Technology dual-hardening process. The self-drilling point and lead tapping threads are selectively hardened to a minimum of HRC 2. The load-bearing portion of the screw is held at or below the critical HRC 34 level. This reduced hardness level also meets SAE J429 Grade and ASTM A449 strength and ductility standards. Dril-Flex fasteners are then coated with silver Stalgard finish to provide superior corrosion resistance and enhanced galvanic compatibility. Fasteners coated with Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces even after 000 hours of % neutral salt spray exposure (ASTM B7). The combination of this unique dual-hardening process and Stalgard finish results in a strong, reliable fastener that can be used where other selfdrillers would fail. Dril-Flex self-drilling fasteners are the ideal fastening solution for demanding construction applications.

4 COMPARISON TO STAINLESS STEEL FASTENERS 300 series stainless steel fasteners will not rust, and, because of their low hardness, they also provide high resistance to hydrogen embrittlement failures. However, because plain-finished stainless steel is galvanically incompatible with certain building materials including steel and aluminum it can cause other problems (see chart) when combined with these materials. Stainless steel fasteners trigger a sacrificial action in the aluminum or steel panel, which can lead to degradation of the panel and loosening of the fastener. The dual-hardening process allows Dril-Flex fasteners to provide high strength and resistance to hydrogen embrittlement failures. Their unique Stalgard finish provides corrosion resistance several times greater than other commonly-used finishes. Fasteners coated with Stalgard finish typically show no red rust or other base metal corrosion on significant surfaces even after 000 hours of % neutral salt spray exposure (ASTM B7). If the environment is corrosive enough to significantly affect the Stalgard finish, the potential for significant degradation of the aluminum/stainless steel assembly would also exist. Galvanic Series Anodic End Metal/Alloy EMF (v) Magnesium Zinc Alum (000, 000, 7000) Iron, Low Alloy Steels Alum (2000) Lead % Chromium Steel Naval Brass Brass, Bronze Austenitic Stainless (300 Series) Nickel Silver... 0 Gold... + Cathodic End In the presence of moisture, materials higher on the list will be sacrificial to materials lower on the list. The greater the EMF differential, the greater the sacrificial action of the anode to the cathode in a galvanic cell. EMBRITTLEMENT TESTING Embrittlement testing of Dril-Flex fasteners was performed in accordance to ASTM F4-0, Standard Test Method for Measurement of Hydrogen Embrittlement in Steel by the Incremental Loading Method. Fastener lots were tested to determine their Threshold Stress Limits for both Internal Hydrogen Embrittlement and Environmental Hydrogen Embrittlement. Threshold Stress Limit is the stress level below which no time-dependent cracking will occur. Above this level, subcritical cracking that leads to time-delayed fracture or embrittlement may occur if the fastener is exposed to a hydrogen environment. Embrittlement Test Results Dril-Flex fasteners have a hardness range of HRC 28 34, which is roughly equivalent to a SAE Grade fastener (HRC 2 34). Dril-Flex fasteners showed resistance to the effect of hydrogen-assisted cracking when loaded to 7% of their tensile strength. This is within accepted industry guidelines for in service loading conditions. Dril-Flex fasteners showed no degradation or failures in tensile strength below their Ultimate Tensile Strength.

Design of the connections must comply with Section E4 of AISI S00 (AISI-NAS for the 200 IBC). Nominal and available fastener tension and shear strengths for the screws are shown in Table 2. Available connection shear, pull-over and pull-out capacities are given in Tables 3, 4 and, respectively. For tension connections, the lowest of the available fastener tension strength, pull-over strength and pull-out strength, in accordance with Tables 2, 4 and, respectively, must be used for design. For shear connections, the lower of the available fastener shear strength and the shear (bearing) strength, in accordance with Tables 2 and 3, respectively, must be used for design. Design provisions for tapping screw connections subjected to combined shear and torsion loading are outside the scope of the report. The connection shear strength is for connections where the connected steel elements are in direct contact with one another. For screws used in framing connections, in order for the screws to be considered fully effective, the minimum spacing between the fasteners and the minimum edge distance must be three times the nominal diameter of the screws, except when the edge is parallel to the direction of the applied force, the minimum edge distance must be. times the nominal screw diameter. When the spacing between screws is 2 times the fastener diameter, the connection shear strength values in Table 3 must be reduced by 20 percent (Refer to Section D. of AISI S200). For screws used in applications other than framing connections, the minimum spacing between fasteners must be three times the nominal screws diameter and the minimum edge and end distance must be. times the nominal screw diameter. Additionally, under the 2009 and 200 IBC, when the distance to the end of the connected part is parallel to the line of the applied force, the allowable connection shear strength determined in accordance with Section E4.3.2 of Appendix A of AISI S00-07 (AISI NAS for the 200 IBC) must be considered. Connected members must be checked for rupture in accordance with Section E of AISI S00- for the 20 IBC (Section E of AISI S00-07/S2-0 for the 20 IBC; Section E of AISI S00-07 for the 2009 IBC).
