Hillman Fasteners 47267 Self-drilling Screw 1/4-14 X 10.5 in 12pk

Product Description

The HILLMAN FASTENERS 47267 is a 1/4-14 x 10.5-inch zinc hex washer head self-drilling screw supplied with an integrated neoprene washer. Designed for metal-to-metal or metal-to-substrate fastening, this screw drills its own pilot hole and taps its own thread in a single pass, eliminating a separate drilling step. The hex washer head accepts a standard hex driver bit or nut driver for fast, repeatable installation. The neoprene washer creates a weather-resistant seal at the fastener head, making it well suited for exterior panels, roofing substrates, and HVAC sheet-metal enclosures. Licensed tradespeople and sheet-metal mechanics rely on this type of fastener for structural and weather-tight connections.

This screw is commonly used in commercial and residential construction applications where sheet metal, light-gauge steel framing, or roofing panels must be secured quickly and reliably. Typical install scenarios include HVAC equipment enclosures, metal roofing and wall panel systems, and light structural steel assembly. The neoprene washer helps prevent water infiltration at penetration points, which is critical for exterior and rooftop applications. Each box contains 12 screws, suitable for small-run repairs or kept as bench stock on a service vehicle.

Key Features

• Self-drilling tip eliminates the need for a separate pilot hole in compatible light-gauge steel
• 1/4-14 thread form provides strong thread engagement in sheet metal substrates
• 10.5-inch length accommodates deeper fastening applications such as thick panel stacks or insulated metal panels
• Zinc finish provides corrosion resistance for exterior and semi-exposed installations
• Hex washer head accepts standard nut drivers and hex-shank power driver bits
• Integrated neoprene washer seals the fastener penetration against moisture intrusion

Compatibility

Designed as an OEM-style replacement or general-use fastener for hex washer head self-drilling screw applications in sheet metal, light-gauge steel framing, and metal panel systems requiring a 1/4-14 thread profile.

Installation Notes

Installation is performed with a hex nut driver or impact driver fitted with a 1/4-inch hex bit; do not overtighten, as excessive torque will compress the neoprene washer past its sealing threshold and strip the drilled thread. Ensure the substrate gauge is within the rated capacity for self-drilling fasteners before driving. Follow applicable building codes and manufacturer panel specifications for fastener spacing and edge distance. Wear appropriate eye protection when drilling into metal substrates.
