Product Overview
Zinc-plated Phillips pan head self-tapping screws by China Quanfan, available in metric (mm): 2.5×6-16, 3×6-30, 4×10-45, 5×8-60, 6×12-60, and imperial (in): #4×1/4-5/8, #5×1/4-1 3/16, #6×3/8-1 3/4, #8×5/16-2 3/8, #10×1/2-2 3/8, are widely used in electronics, furniture, auto parts, and home appliance assembly. Zinc plating boosts rust/corrosion resistance for humid/mildly corrosive environments; Phillips recess enables efficient installation with a matching screwdriver. Pan heads (flat-round with curved top and flanged edges) offer aesthetics and bearing area for light appearance needs. Self-tapping design with sharp tips eliminates pre-drilling, threading into metal/plastic to simplify joining thin sheets and plastic parts.

Application Scenarios
Zinc Plated Phillips Pan Head Self-Tapping Screws excel in electronics (securing casings, circuit boards) with corrosion resistance against moisture. In furniture, they join wood/plastic hardware efficiently, with pan heads ensuring a clean look. Automotive uses include interior trims and brackets, leveraging self-tapping for thin metals/plastics. They’re ideal for DIY/construction (roofing, PVC) and toys/sports gear, offering safe, tool-friendly installation. Zinc plating resists dampness; Phillips drive speeds assembly, making them versatile for light-duty, moderately exposed applications.
