1/4" ZAC® Type AB Self-Tapping Screw, Zinc Alloy Capped HWH | ZTABMP-14

• Zinc alloy cap head that will never red rust
• Assembled EPDM sealing washer for a consistent weather tight seal
• Long life fastener limited warranty

Metal panel to medium metal applications or metal panel to wood applications

• Tools metal to metal application;  install fasteners with 0–1000 rpm screw gun equipped with depth sensing nose piece.
• Tools metal to wood application; install fasteners with 0–2500 rpm screw gun equipped with depth sensing nose piece.
• Use of impact guns or hammer drill is not recommended.
• Self-drilling metal thickness: sheet 0.018"–0.030" (0.46 mm–0.72 mm)
• Metal thickness/drill bit size
• 0.065"–0.085" (1.65 mm–2.16 mm);  drill bit size #8 (5.05 mm)
• 0.085"–0.115" (2.16 mm–2.92 mm);  drill bit size #7 (5.11 mm)
• 0.115"–0.375" (2.92 mm–9.53 mm);  drill bit size #1 (5.79 mm)
• 0.375"–0.500" (9.53 mm–12.7 mm); drill bit size #1 or larger depending on hardness of steel
• The hole size determines installation performance and pull out strength. Thickness is based on normal, single thickness purlin/girt or multiple material thickness combined for total.
• Special care needs to be taken when installing into wood substrate less than 1" in thickness. Stripping or partially stripping the fastener out during installation compromises the clamp load and can affect the performance of the fastener.
• Thickness is based on normal, single thickness purlin/girt or multiple material thickness combined for total. Minimum depth penetration into wood substructure 1" (25.4 mm)
