Hillman Fasteners 560276 Drill Screw 8-18x1 in Zinc 100pk

Product Description

The HILLMAN FASTENERS 560276 is a zinc-plated pan head Phillips drive drill screw sized 8-18 x 1 inch, sold in a 100-pack. Drill screws in this configuration feature a self-drilling tip that eliminates the need for a pilot hole, allowing direct fastening into light-gauge sheet metal, metal framing, and similar substrates. The pan head profile provides a broad bearing surface, and the Phillips drive is compatible with standard power bits. Zinc plating offers baseline corrosion resistance for dry and semi-exposed interior applications. Each pack contains 100 identical fasteners, suited for volume work on HVAC ductwork, metal stud assemblies, and electrical enclosures.

This screw is commonly used by HVAC technicians for securing duct sections, sheet metal panels, and equipment covers where a self-drilling fastener is required. Electricians and metal framing contractors also reach for this size when working with light-gauge steel. The 8-18 thread designation indicates a No. 8 shank diameter with 18 threads per inch, appropriate for single-layer or thin stacked sheet metal connections.

Key Features

• Self-drilling tip eliminates the need for a separate pilot hole in light-gauge sheet metal
• Pan head profile provides a wide bearing surface and low-profile finish
• Phillips drive compatible with standard No. 2 power bits
• Zinc plating provides corrosion resistance for interior and semi-protected applications
• 8-18 x 1 inch size suited for light-gauge steel ductwork and metal framing
• 100-pack quantity supports volume fastening tasks on larger jobs

Compatibility

Designed as a standard self-drilling fastener for light-gauge sheet metal applications including HVAC ductwork, metal stud framing, and electrical enclosures where an 8-18 x 1 inch pan head Phillips screw is specified.

Installation Notes

Installation is performed with a No. 2 Phillips bit in a variable-speed drill or screw gun set to an appropriate clutch setting to avoid stripping the head. Confirm that the substrate gauge falls within the rated range for the self-drilling tip before driving. For HVAC duct applications, follow SMACNA guidelines for fastener spacing and engagement. Avoid overtightening, which can strip the pan head or deform thin sheet metal.
