Hillman Fasteners 47265 1/4-14x1 Zinc Hex Washer Sd Screw 12pk

Product Description

The HILLMAN FASTENERS 47265 is a 1/4-14 x 1 inch zinc-plated hex washer head self-drilling screw with an integrated neoprene washer. Sold in a box of 12, these fasteners are designed to drill, tap, and fasten in a single pass — no pre-drilling required. The hex washer head allows standard hex-driver installation, and the neoprene washer creates a weatherproof seal at the fastening point. Zinc plating provides corrosion resistance for exterior and semi-exposed applications. This combination of sealing washer and self-drilling point makes these screws a common choice for metal panel, roofing, and light structural assembly work.

These screws are suited for light commercial and residential construction applications where a weather-resistant fastener is needed. Typical uses include attaching metal roofing panels, corrugated metal sheeting, HVAC sheet metal enclosures, metal trim, and similar substrates. The neoprene washer compresses under the hex head to prevent moisture ingress at the fastener hole. Installers working on metal-to-metal or metal-to-light-gauge applications will find the self-drilling point reduces labor time compared to standard machine screws.

Key Features

• Self-drilling point eliminates need for pre-drilling in compatible gauge materials
• Hex washer head accepts standard 1/4-inch hex driver bits
• Integrated neoprene washer creates a compression seal against moisture
• Zinc plating provides corrosion resistance for exterior-rated applications
• 1/4-14 thread form designed for metal fastening applications
• Packaged in a box of 12 for jobsite use

Compatibility

Designed as a standard hex washer head self-drilling screw for use in metal roofing, sheet metal enclosure, and light structural panel fastening applications.

Installation Notes

Installation is performed with a power drill or impact driver fitted with a 1/4-inch hex driver bit. Apply consistent axial pressure when starting the self-drilling point to prevent walking on smooth metal surfaces. Do not overtighten — excess torque will compress the neoprene washer beyond its sealing range and can strip the fastener hole. Follow applicable building code requirements for fastener spacing and pull-out ratings on structural panel applications.
