Pan Head Self Drilling Screw for Metal-Phillips Drive Self Tapping Sheet Metal Tek Screw

description

1. Performance & Material Properties
   • Dual‐Grade Stainless Construction: Choose martensitic AISI 410 (tensile 700–800 MPa, hardness 30–38 HRC) for superior wear resistance, or austenitic AISI 304 (tensile 500–600 MPa, excellent pitting and crevice-corrosion resistance) for harsh or marine environments.
   • Full-Thread Shank: Rolled threads extend from head to tip, delivering maximum clamp load and vibration resistance in panels 0.8–3.0 mm thick without relying on pilot holes.
   • Self-Drilling “TEK” Point: Precision-ground flute hardened to Rc 45–50 drills through 0.5–2.5 mm mild steel or aluminum in one pass. Spiral chip-evacuation geometry minimizes heat buildup and galling, eliminating pre-drilled holes.
   • Phillips Drive Pan Head: Ø 10–12 mm pan head with a deep cruciform recess resists cam-out up to 6 Nm torque, distributes load evenly, and provides a neat, slightly raised finish.
2. Detailed Application Range
   • Metal Roofing & Cladding: Secure corrugated, standing-seam, or composite panels, soffits, fascia, gutters, and architectural façades in residential, commercial, and light-industrial buildings.
   • HVAC & Ductwork: Fasten spiral and rectangular ducts, plenums, access panels, grille frames, and diffuser plates where airtight, vibration-resistant joints are critical.
   • Electrical & Equipment Enclosures: Mount junction boxes, control cabinets, cable trays, light fixtures, and machinery guards in indoor or sheltered outdoor installations.
   • Automotive, Marine & Industrial Fabrication: Ideal for body-panel brackets, interior trim, signage frames, display fixtures, and light machinery housings—especially where corrosion and reliability are key.
3. Effortless Installation & Operation
   • One-Step Drill & Tap: Integrated self-drilling tip and full-thread design eliminate separate pilot drilling and tapping operations—reducing installation time by up to 50 % and ensuring precise, repeatable hole entry on angled or overhead surfaces.
   • Phillips #2 Bit Compatibility: Deep cruciform recess engages standard Phillips bits or low-torque drivers with minimal cam-out, reducing bit wear and operator fatigue.
   • Controlled Seating & Anti-Overdrive Shoulder: Built-in head shoulder prevents over-insertion and substrate distortion; screws seat flush or slightly proud for a clean aesthetic.
   • Clean Removal & Rework: Screws back out without enlarging the formed hole, enabling quick repositioning or component servicing without thread damage.
4. Superior Quality & Long-Term Reliability
   • ISO 9001 & ASTM/ANSI Compliance: Manufactured in ISO 9001–certified facilities to ANSI B18.6.4 and DIN 7504 P tolerances (±0.1 mm diameter, ±0.2 mm length), ensuring global interchangeability and dimensional accuracy.
   • Rigorous Corrosion & Mechanical Testing: 304 screws endure ≥720 h neutral salt-spray (ASTM B117); 410 screws resist ≥240 h salt-spray with black-oxide or passivated finishes. Each batch undergoes drive-torque and head-pull-off verification under dynamic loads.
   • Passivation & Finish Integrity: Post-manufacture nitric-acid or chromate passivation restores the chromium-oxide barrier, preventing staining and enhancing durability in mildly corrosive atmospheres.
   • Full Traceability & Environmental Compliance: Lot-coded from melt to finished part, accompanied by material certificates. RoHS- and REACH-compliant, free of hexavalent chromium and other restricted substances—guaranteeing both performance and regulatory peace of mind.
