Hillman Fasteners 47263 Self-drilling Screw 12-14 X 1.5 in Box 12

Product Description

The HILLMAN FASTENERS 47263 is a zinc-plated hex washer head self-drilling screw with an integrated neoprene washer, sized 12-14 x 1.5 inches. The self-drilling point eliminates the need for a pilot hole, speeding up installation in metal-to-metal or metal-to-substrate applications. The hex washer head provides a broad bearing surface for consistent clamping force, while the neoprene washer creates a weather-resistant seal at the fastener point. These screws are sold in a box of 12 and are suited for trade professionals working on roofing, cladding, HVAC enclosures, and light-gauge metal framing assemblies.

These self-drilling screws are commonly used in residential and light commercial construction and mechanical service work where sheet metal panels, flashing, or equipment enclosures must be fastened securely without pre-drilling. Typical applications include HVAC equipment panels, metal roofing, and ductwork access covers. The neoprene washer is especially valuable in exterior or exposed installations where moisture intrusion at the fastener point is a concern.

Key Features

• Self-drilling point eliminates pilot hole requirement on light-gauge metal
• Zinc plating provides corrosion resistance for interior and light exterior use
• Integrated neoprene washer seals the fastener point against moisture
• Hex washer head accepts standard hex driver bits for fast installation
• 12-14 thread size suits light-gauge sheet metal fastening
• Sold in a box of 12 for convenient jobsite quantities

Compatibility

Designed as a general-purpose self-drilling fastener for light-gauge metal applications including sheet metal panels, roofing, and equipment enclosures where a sealing washer is required.

Installation Notes

Installation is performed with a hex-head driver bit in a variable-speed drill or impact driver — avoid over-driving, which can compress the neoprene washer beyond its effective sealing range. Power down any equipment and de-energize panels before fastening into or adjacent to electrical enclosures or HVAC units. Follow applicable building codes for fastener spacing on roofing and cladding assemblies.
