Itw Buildex 560090 Hex Washer Head Sheet Metal Screw 100pk

Product Description

The ITW BUILDEX 560090 is a Type AB hex washer head sheet metal screw designed for fastening metal-to-metal and metal-to-light-gauge steel applications. Built from stainless steel, this screw delivers corrosion resistance suited to outdoor, coastal, and high-moisture environments. The 17-14 thread size and 1 inch length under head make it a standard choice for ductwork, metal panels, electrical enclosures, and HVAC equipment housings. The hex washer head provides a broad bearing surface for secure clamping without a separate washer. Installers use a hex driver or nut driver for installation. Sold in a pack of 100.

This screw is well suited for light commercial and residential sheet metal work where a corrosion-resistant fastener is required. Common applications include HVAC duct assembly, sheet metal panel attachment, metal framing connections, and electrical enclosure fabrication. The Type AB point is a dual-purpose point that works with both sheet metal and light-gauge steel, making it versatile across trade disciplines including HVAC, electrical, and plumbing rough-in work involving metal components.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or plumbers securing sheet metal components during rough-in or equipment installation. Use a hex driver or nut driver sized to the hex washer head to avoid stripping. De-energize any electrical equipment and shut off HVAC systems before fastening enclosures or duct sections. Do not overtighten stainless steel screws, as the material is susceptible to galling under excessive torque.
