Product Description

Modified Truss Head Self-Drilling ScrewSS410M4.2M4.8

Key Features

1. Superior Corrosion Resistance

The zinc coating provides a robust barrier against oxidation, making these screws suitable for indoor and outdoor applications. Hot-dip galvanized variants (optional) deliver enhanced protection for harsh environments (e.g., coastal areas, chemical plants). With a typical zinc thickness of 8–12 microns, they withstand ASTM B117 salt spray tests for 500+ hours without red rust.

2.Self-Drilling Efficiency

Equipped with a hardened drill point (HRC 50–55), these screws eliminate the need for pilot holes, reducing labor costs by up to 30%. The flute design effectively removes debris during drilling, preventing thread stripping and ensuring smooth installation.

3. High Load-Bearing Capacity

- Tensile Strength: 800–1,000 MPa

- Shear Strength: 600–750 MPa

The hardened steel core and deep threads provide excellent grip strength, ideal for dynamic loads

4. Versatile Head & Drive Options

- Head Styles: Hex washer head, pan head, or countersunk head for flush finishes.

- Drive Types:Phillips, Pozidriv, or Torx (T15/T20/T25) to prevent cam-out under high torque.

The hex washer head distributes pressure evenly, reducing surface damage and improving sealing.

5. Wide Size Range

Available in diameters from #8 to 1/4 inch (4.2mm–6.3mm) and lengths from 1/2" to 6" (12mm–150mm), customizable for specialized projects.

6. Compliance & Certification

Meets ISO 9001, ASTM F1514, and DIN 7504 standards. RoHS-compliant and REACH-certified for EU markets.
