Dynamic Fastener Dynamic Fastener’s 14-20 by 1 1/2-inch Fenderhead T-5 has a built-in fender washer-like face under the head. The 5/8-inch outside diameter (OD) washer face provides pullover strength. It also creates additional bearing area compared to a 7/16-inch (OD) washer face. The fastener’s stout head height eliminates wobble and transfers screw-gun torque efficiently to the screw’s drill tip. It can self-drill through 5/8-inch-thick steel and is offered in seven lengths: 1 1/2-, 2 1/4-, 3-, 4-, 5-, 6- and 8-inch. All Fenderhead fasteners have Dyna-Coat 1,000-hour salt spray coating. |

They attach metal panels to light steel girt, purlin and wood. The #10 diameter fasteners are available in lengths 1 inch to 4 inches. The low-profile #12 Truss head is well-suited for exposed fastener residential roofing. The fasteners’ high hex washer heads drill and tap to 16-gauge-thick metal. Their drilling capability eliminates dimpled panels. |

ST Fastening Systems ST Fastening Systems’ WOODBINDER ZXL fasteners have molded (not capped) ZAMAC 5 zinc-aluminum alloy heads, which provide lifetime protection against red rust on the heads. They have EPDM rubber washers that fit into cavities under the molded heads to prevent washer over-driving. WOODBINDER ZXL fasteners also have a MB micro-bit point. The point drills steel panels consistently, generates small metal chips and eliminates pig-tails common with sharp point screws. Their KWIKSEAL thread pattern provides holding strength in wood substrates. |
