Hillman Fasteners 47206 Hex Washer Head Self-drilling Screw

Product Description

The HILLMAN FASTENERS 47206 is a No. 8 by 3/4 inch zinc coated hex washer head self-drilling screw sold in a box of 12. The self-drilling point eliminates the need for a pilot hole, allowing direct fastening into light-gauge metal, sheet metal, or similar substrates. The hex washer head provides a broad bearing surface and is driven with a standard hex driver or nut driver. The zinc coating offers basic corrosion resistance for general interior and light exterior applications. This fastener is used by HVAC technicians, sheet metal workers, electricians, and general contractors for panel attachment, ductwork assembly, and light structural fastening tasks.

The 47206 is suited for light-gauge metal-to-metal and metal-to-substrate fastening in residential and commercial construction and mechanical applications. Typical uses include securing sheet metal panels, HVAC duct sections, electrical enclosures, and similar assemblies where a self-drilling fastener speeds installation. The zinc coating makes these screws appropriate for dry or occasionally damp interior environments. Each box contains 12 screws, supporting small repairs and targeted installations.

Key Features

• Self-drilling point eliminates pilot hole requirement for faster installation in light-gauge metal
• Hex washer head provides broad bearing surface and positive driver engagement
• Zinc coating delivers basic corrosion resistance for interior and light exterior use
• No. 8 diameter at 3/4 inch length suits thin-material fastening applications
• Sold in a box of 12 for small-quantity and service repair needs

Compatibility

Designed as a general-purpose self-drilling screw for light-gauge metal fastening applications in HVAC, electrical, and sheet metal work.

Installation Notes

Self-drilling screws are installed by sheet metal workers, HVAC technicians, and electricians using a hex driver bit in a standard drill or screw gun set to an appropriate clutch setting to avoid overdriving. Ensure the workpiece is secured before driving. Do not exceed the material thickness rating for the self-drilling point, as overloading will prevent proper thread engagement. Follow applicable mechanical and building codes for fastener spacing and pull-out requirements in structural or pressure-boundary applications.
