Pan Head Self-Tapping Screws
Product Overview
The SS304 Stainless Steel US Standard Square Drive Pan Head Self-Tapping Screw is a high-performance fastener manufactured in strict accordance with ASME/ANSI B18.6.3 standards. Made from food-grade 304 austenitic stainless steel, it combines a pan head, square drive, and self-tapping sharp point into a single reliable fastening solution. The self-tapping design eliminates the need for pre-threading, allowing direct installation into wood, plastic, and thin sheet metal. It offers easy installation, secure fastening, and long-lasting durability, making it an ideal choice for furniture manufacturing, outdoor construction, equipment assembly, and many other applications.
Product Applications
Furniture Manufacturing: Widely used for assembling solid wood furniture, panel furniture, and outdoor furniture. The corrosion-resistant 304 stainless steel is especially suitable for balconies, patios, gardens, and other outdoor environments, while the pan head provides a clean, attractive finish.
Building and Interior Construction: Suitable for fastening light steel framing, joining wood panels, and installing materials in kitchens, bathrooms, and other moisture-prone areas. Its excellent corrosion resistance helps prevent structural loosening caused by rusted fasteners.
Equipment and Sheet Metal Assembly: Ideal for assembling plastic enclosures, thin sheet metal equipment, and electrical housings. The self-tapping design enables fast installation, while the square drive provides reliable, high-torque fastening for industrial assembly applications.
US Standard Export Products: Manufactured to US standard specifications, these screws are fully compatible with equipment, tools, and components designed to US standards. They are an excellent fastening solution for export products without requiring additional specification adjustments.
Product Features
304 Stainless Steel Construction: Provides excellent corrosion and rust resistance, making it suitable for humid and outdoor environments. It offers a significantly longer service life than ordinary zinc-plated screws while maintaining excellent toughness and resistance to deformation or fracture.
Square Drive Design: Delivers efficient torque transmission with greater contact area, reducing cam-out during installation. It is ideal for high-torque fastening applications and offers improved tamper resistance.
Pan Head Design: Provides a neat and attractive finished appearance. The larger bearing surface helps distribute clamping force evenly and reduces the risk of damaging the workpiece surface.
US Standard Self-Tapping Thread: The optimized sharp point enables fast installation without pre-tapping, making it suitable for wood, plastic, thin sheet metal, and other materials.
