Hillman Fasteners 47214 Hex Washer Self-drilling Screw 1in No.10

Product Description

The HILLMAN FASTENERS 47214 is a zinc-coated hex washer head self-drilling screw sized at 1 inch in length and No. 10 in diameter. The hex washer head allows for fast driving with a nut driver or hex-tip power bit, eliminating the need for a separate pilot hole. The self-drilling point bores through light-gauge metal and thin sheet material in a single step. The zinc coating provides basic corrosion resistance for indoor and light-duty applications. These screws are used by HVAC technicians, sheet metal workers, electricians, and general contractors for securing duct assemblies, metal framing, junction boxes, and similar light metal connections.

This screw is suited for light commercial and residential installations where speed and convenience matter. Common applications include attaching sheet metal duct sections, fastening thin-gauge steel brackets, securing electrical enclosures, and general sheet metal assembly. Each box contains 12 screws, making this a convenience pack appropriate for small jobs or stock replenishment on service vehicles.

Key Features

• Self-drilling point eliminates pre-drilling on light-gauge metal

Compatibility

Designed as a general-purpose self-drilling fastener for light-gauge sheet metal applications in residential and light commercial HVAC, electrical, and general construction work.

Installation Notes

Installation does not require a pilot hole in light-gauge metal when using the self-drilling point. Drive with a hex-tip bit or nut driver at a controlled speed to avoid stripping the head or overdriving through thin material. Power down or de-energize any electrical enclosure before fastening into or near live panels. Follow applicable local building and mechanical codes for fastener type and spacing requirements.
