Self Tapping Screws are self-drilling fasteners designed to create their own thread in non-metallic or thin metal materials, eliminating the need for pre-tapped holes. Ideal for applications in sheet metal, plastic, wood, and composite panels, they feature sharp threads, pointed tips, and various head styles (Phillips, hex, pan) for easy installation. Manufactured from carbon steel (zinc-plated), stainless steel (304/316), or aluminum, these screws offer high efficiency and secure fastening.
- Material:
- Carbon Steel (Grade 4.8/8.8, zinc-plated or black oxide).
- Stainless Steel (304/316, passivated for corrosion resistance).
- Aluminum/Brass: For lightweight or non-magnetic applications.
- Size Range:
- Diameter: #2–#14 (imperial) / M2–M8 (metric).
- Length: 6–60 mm (custom lengths up to 100 mm available).
- Thread Types:
- Type AB: General-purpose for sheet metal (1.6–3 mm thickness).
- Type C: Cutting threads for harder materials (e.g., stainless steel sheets).
- Type F: Fine threads for plastics and composites.
- Head Styles: Phillips, slotted, pan, countersunk, hex washer head.
- Coating: Zinc plating (RoHS/REACH compliant), Dacromet, or PTFE (low friction).
- Standard Carbon Steel/Zinc-Plated: 10,000 pieces (common sizes like #8 x 1" in stock).
- Stainless Steel/Custom Types: 5,000 pieces (e.g., Type C or countersunk heads).
Factory Advantages: ISO-certified production, precision thread forming (tolerance: ±0.01mm), support for special thread types (e.g., self-drilling/Tec screws) and custom coatings, with lead times of 7–15 days for standard orders.
- Sheet Metal Fabrication: HVAC ducts, automotive body panels, and metal roofing.
- Plastic & Composite Assembly: Enclosures for electronics, furniture, and outdoor equipment.
- DIY & Construction: Installing drywall, trim, and insulation in residential projects.
- Industrial Equipment: Securing panels, filters, and access covers in machinery.
- Self-Drilling Efficiency: Sharp tips and aggressive threads reduce installation time by 50% compared to traditional screws.
- Corrosion Resistance:
- Stainless steel options (316) for coastal or chemical environments.
- Dacromet coating (1,000+ hours salt spray) for heavy-duty use.
- Secure Hold: Thread designs prevent stripping in soft materials like PVC or MDF.
- Non-Standard Sizes: Oversized heads, extended lengths, or micro self-tapping screws (M2–M3).
- Special Coatings: Anti-corrosive (zinc-aluminum), conductive (nickel), or color-matched (RAL tones).
- Head Modifications: Security heads (e.g., Tamper-Proof Torx) for anti-theft applications.
