About this item

41891 – #12‑14 x 1‑1/4" Self‑Drilling Screw (Hex Washer Head)

The Hillman 41891 #12‑14 x 1‑1/4" Self‑Drilling Screw is a heavy‑duty, multi‑material fastener designed for secure metal‑to‑metal, metal‑to‑wood, and metal‑to‑fiberglass connections. Its integrated hex washer head paired with a bonded neoprene washer makes it ideal for applications where a strong mechanical hold and weather‑resistant seal are essential, such as roofing, exterior panels, HVAC mounts, and general construction.

Key Features

  • Self‑drilling point eliminates the need for pre‑drilled pilot holes, capable of penetrating thin‑to‑medium gauge steel, wood, fiberglass, and plastics.
  • Hex washer head provides excellent driving stability and surface contact, preventing pull‑through under load.
  • Bonded neoprene washer creates a watertight seal and prevents corrosion or galvanic reaction between fastened materials.
  • Sharp thread profile cuts its own mating threads for tight, durable holding strength.
  • Zinc‑plated steel construction for moderate corrosion resistance in outdoor or semi‑exposed environments.
