Hillman Fasteners 47294 Flat Head Self-drilling Screw 12-24 X 2.5 in

Product Description

The HILLMAN FASTENERS 47294 is a flat head self-drilling screw with wings, sized at 12-24 x 2.5 inches and finished with a 1000-hour ceramic coating for corrosion resistance. The wings on the tip help clear material during penetration, making this screw well-suited for fastening metal to wood or composite substrates without pre-drilling. Sold in a box of 12, this fastener is a practical choice for HVAC installers, sheet metal workers, and general contractors who need a reliable, corrosion-resistant fastener for light commercial or residential applications.

This screw is commonly used in applications where metal panels, brackets, or framing components are fastened to wood or similar base materials. The flat head profile sits flush with the work surface, which is important in panel and trim installations where a low-profile finish is required. The ceramic coating provides extended corrosion resistance, making it suitable for exterior or moisture-prone environments.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or general contractors using a standard power drill or screw gun with the appropriate bit size for the flat head drive. Power down or de-energize any equipment in the work area before fastening components to live panels or enclosures. Ensure the substrate material is compatible with self-drilling fasteners to avoid splitting or stripping. Follow applicable local building codes for fastener spacing and load requirements.
