Metric Steel Zinc-plated Truss Head Self Drilling Screw for Fixing Steel Pur Strips

Metric Steel Zinc-plated Truss Head Self Drilling Screw for Fixing Steel Pur Strips

Product Overview

Optimize the installation of steel purlin strips in industrial, agricultural, and commercial buildings with our Metric Steel Zinc-Plated Truss Head Self-Drilling Screws. Designed for speed, durability, and structural integrity, these screws combine a self-drilling tip, corrosion-resistant zinc coating, and a truss head design to secure metal-to-metal connections effortlessly. Ideal for roofing, cladding, and structural framing, they ensure reliable performance in demanding environments.

Key Features

✅ Self-Drilling Efficiency

  • Sharp, Winged Drill Point: Penetrates steel purlin strips (up to 2.5mm thickness) without pre-drilling.
  • Coarse Threads: Aggressive grip for rapid installation and vibration resistance.

✅ Truss Head Design

  • Wide Bearing Surface: Distributes load evenly, preventing pull-through and material deformation.
  • Low-Profile Finish: Sits flush with surfaces for a smooth, snag-free fit.

✅ Zinc-Plated Corrosion Resistance

  • Electro-Galvanized Coating (5–8µm): Protects against rust and oxidation in outdoor or humid conditions.
  • Cost-Effective Durability: Ideal for general construction and non-coastal applications.

✅ Metric Precision Sizing

  • Diameter: M4.8 (≈#10), M5.5 (≈#12), M6.3 (≈1/4") – optimized for steel purlin connections.
  • Length: 20mm–50mm (custom lengths up to 100mm available).

✅ Certified Strength

  • Grade 8.8 Carbon Steel: Tensile strength up to 800 MPa for structural integrity.
  • ISO 1478, ASTM B633: Compliant with international standards.
