Acorn SW-MW2FG250 Metal to Wood Screw Forest Green 250ct

Product Description

The ACORN SW-MW2FG250 is a 2-inch metal-to-wood self-piercing, self-tapping screw designed for roofing and siding applications. Manufactured from heat-treated C1022 steel with case hardening, each screw features a 1/4-inch across-flat high-hat hex washer head with an assembled EPDM (Ethylene Propylene Diene Monomer) sealing washer. The twin-lead Type 17 point combined with hi-lo threads reduces drive time and increases pull-out resistance. A dacro base coating provides 1,000-hour salt spray corrosion protection, with a forest green powder coat applied over the dacro for color-matched installations. Sold in a 250-count pack.

These screws are suited for attaching metal panels, roofing sheet, and siding to wood substrates in both residential and light commercial construction. The EPDM washer conforms to irregular surfaces, creating a weatherproof seal at each fastener point. The hex washer head drives cleanly with a standard hex driver bit, making them practical for high-volume panel installation work. Roofing contractors, siding installers, and general contractors are the primary users of this fastener type.

Key Features

• Heat-treated C1022 steel construction with case hardening for durability in roofing and siding use
• 1/4-inch across-flat high-hat hex washer head with assembled EPDM sealing washer for a weatherproof seal
• Twin-lead Type 17 point and hi-lo threads for faster drive time and increased pull-out resistance
• 1,000-hour salt spray tested dacro base coating for corrosion resistance
• Forest green powder coat over dacro base for color-matched panel applications
• 250 screws per pack for efficient job-site stocking

Compatibility

Designed as an OEM-style metal-to-wood fastener for roofing and siding panel systems requiring a color-matched, sealing hex washer head screw into wood structural members.

Installation Notes

Installation is performed by roofing and siding contractors using a hex driver bit sized to the 1/4-inch across-flat head. Drive screws perpendicular to the panel surface to allow the EPDM washer to seat and seal correctly — angled driving can compromise the weatherproof seal. Do not overdrive; excessive torque will distort the EPDM washer and reduce sealing effectiveness. Follow applicable building codes and panel manufacturer fastener spacing requirements for the specific application.
