About this item
#8‑18 x 3" Self‑Drilling Screw – Hex Washer Head (75 Count)
Heavy‑Duty, Long‑Reach Fastening for Metal, Wood, and Composites
The #8‑18 x 3" Self‑Drilling Screw with Hex Washer Head is engineered for applications that demand long fastening reach, strong holding power, and the ability to penetrate materials without the need for pre-drilling. With its extended 3‑inch length, aggressive thread profile, and integrated hex washer head, this screw is ideal for structural assemblies, metal framing, HVAC installation, heavy-duty fastening, and general construction tasks where a dependable self‑drilling fastener is required.
Constructed from high‑quality steel and coated for improved durability, these screws deliver consistent drilling performance and tight material engagement. Packaged in a 75‑count box, they offer reliable supply for both professional contractors and experienced DIY installers.
Key Features
Self‑Drilling Tip Designed to drill its own pilot hole, enabling quick installation through sheet metal, thin steel, aluminum, plastics, and wood.
Hex Washer Head Design Provides excellent driving stability, distributes pressure evenly across the fastened surface, and minimizes the risk of pull-through.
Extended 3" Length Allows for deeper penetration into layered materials, structural components, or thicker build‑ups where standard fasteners may fall short.
High‑Strength Steel Construction Ensures dependable holding power and long-term fastener integrity, even in demanding applications.
Corrosion‑Resistant Coating Protects against rust and wear, making the screws suitable for indoor or lightly exposed environments.
Sharp, High‑Thread Count (#18 Thread) Enhances gripping strength and improves engagement in a wide range of materials.
75‑Count Contractor Pack Provides an efficient supply for jobsite use, maintenance shops, or high‑volume installation tasks.
