Hex Head Self Drilling Screw (Tek Screw) | Zinc Plated
Product Overview
The Hex Head Self Drilling Screw (also known as Tek Screw) features a drill point tip that enables it to drill its own hole and tap threads in a single operation. This eliminates the need for pre-drilling, saving significant time and labor.
Designed with a hexagonal washer head, it provides high torque transmission and a secure grip, making it ideal for metal-to-metal or metal-to-wood fastening.
Key Features
Self-Drilling Tip: Hardened drill point (Tek Point) penetrates steel up to 5mm thick without pilot holes.
Hex Washer Head: Integrated washer flange ensures tight clamping and prevents leaks (often used with EPDM washers).
High Efficiency: Drills, taps, and fastens in one step, speeding up installation.
Corrosion Resistance: Zinc Plated or Dacromet coating provides excellent protection against rust in outdoor environments.
