Made from heat-treated C1022 steel with a case-hardened finish, each screw features a 1\/4-inch across-flat high-hat hex washer head with an assembled EPDM (Ethylene Propylene Diene Monomer) washer that conforms to the surface and creates a lasting weatherproof seal. The twin-lead Type 17 point and hi-lo thread pattern deliver faster drive times and increased pull-out resistance. All screws carry a 1,000-hour salt spray rating with a dacro base coating. Sold in packs of 250.\u003c\/p\u003e\u003cp\u003eThese screws are suited for residential and light commercial roofing and siding installations where a reliable metal-to-wood connection is required. The EPDM washer seals around the fastener on contact, making them a standard choice for attaching metal roofing panels, corrugated cladding, and metal siding to wood framing or decking. The hex washer head allows use with standard hex-drive power tools for efficient installation across large surface areas.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSelf-piercing design eliminates the need for pre-drilling in typical roofing and siding applications\u003c\/li\u003e\n\u003cli\u003eHeat-treated C1022 steel construction with case hardening for strength and durability\u003c\/li\u003e\n\u003cli\u003eAssembled EPDM washer seals against moisture infiltration and conforms to irregular surfaces\u003c\/li\u003e\n\u003cli\u003eTwin-lead Type 17 point with hi-lo threads for faster drive time and greater pull-out resistance\u003c\/li\u003e\n\u003cli\u003eDacro coating rated to 1,000 hours of salt spray exposure for corrosion protection\u003c\/li\u003e\n\u003cli\u003e1\/4-inch across-flat hex washer head compatible with standard power drivers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style fastener for metal-to-wood roofing and siding applications where a self-piercing, sealing screw with an EPDM washer is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by roofing or siding contractors using a hex-drive bit sized to the 1\/4-inch across-flat head. Avoid overtightening, as excessive torque can compress the EPDM washer beyond its sealing range and reduce effectiveness.
