Sheet Metal Screws

Sheet Metal Screws: What You Need to Know

Sheet metal screws, also called self-tapping screws or metal fasteners, are designed for securing thin metal sheets, wood, and plastic. Featuring sharp, cutting threads, they create a secure hold in both hard and soft materials, ensuring long-term durability and structural strength. Available in various head types and materials, they provide versatile fastening solutions across construction, automotive, and roofing projects.

Types:

• Hex Screws: Feature a six-sided head, allowing for higher torque and reduced stripping. Ideal for heavy-duty applications where a secure grip is required.
• Phillips Screws: Have a cross-head design that distributes force evenly, minimizing cam-out. Widely used in general construction and metalwork.
• Slotted Screws: Have a single straight groove, designed for use with flathead screwdrivers. Suitable for light-duty applications and quick installations.
• Square Screws: Feature a square recess head, providing a secure grip and reducing slippage. Preferred for high-torque applications where precision and strength are required.
• Hex Roofing Screws: Include a weatherproof seal, making them suitable for exterior roofing applications. Their corrosion resistance ensures longevity and protection against environmental exposure.

Features:

• Carbon Steel: Strong and durable, suited for high-stress applications. Provides excellent structural support but requires protective coatings to prevent rusting.
• Electro Galvanized Zinc: Coated with a thin layer of zinc for enhanced corrosion resistance. Ideal for outdoor and high-moisture environments.
• Metal: General-purpose metal screws offer solid strength and moderate corrosion resistance, suitable for both indoor and outdoor applications.
• Phosphate: Phosphate-coated screws provide increased friction, improving grip and holding power. Also offers enhanced rust protection.
• Stainless: Stainless steel screws resist corrosion and rust, making them ideal for marine and outdoor applications.
• Uncoated: Used in dry environments where corrosion is not a major concern. Offers a clean finish and high strength.
• Zinc Plated: Provides long-term corrosion resistance and a bright, clean appearance. Ideal for roofing and exterior use.

Sizing:

• #4 to #6: Suitable for thin metal sheets, plastic, and lightweight wood panels.
• #7 to #10: Ideal for medium-duty applications such as metal roofing and wood-to-metal fastening.
• #12 to #14: Designed for heavy-duty projects, including framing and structural work.
• #20: Provides maximum holding strength for thick metal sheets and high-stress installations.
