Self-Tapping Screw N 104 420 03

Secure plastic and sheet-metal components quickly and reliably with the genuine self-tapping screw (part N 104 420 03). Engineered to Volkswagen Group’s exact specifications, this screw cuts its own mating thread as it installs, ensuring a firm clamp load and long-term resistance to vibration.

Key Benefits

• Exact OEM Specification
  Thread diameter, pitch, and head dimensions match factory requirements for direct drop-in replacement—no pre-threading or adapters needed.

• Hardened Steel Construction
  High-carbon alloy offers superior tensile strength and wear resistance under repeated installation cycles.

• Corrosion-Resistant Finish
  Zinc-nickel plating protects against rust and environmental damage, extending service life in oily or moisture-prone areas.

• Sharp Thread Profile
  Precision-ground threads form clean, burr-free mating threads in plastics and thin metals, minimizing material damage and ensuring a secure grip.

• Pan-Head Drive
  Low-profile pan head with Phillips recess allows flush seating and fast installation using standard PH2 screwdrivers or power tools.

Installation Overview

1. Align Parts: Position the components and ensure pilot holes (if used) are centered.

2. Start Screw: Hand-thread the screw into the substrate until the threads engage smoothly.

3. Drive to Seat: Using a PH2 screwdriver or torque-controlled driver, tighten the screw until the pan head sits flush without over-torquing.

4. Verify Secure Fit: Confirm there is no looseness or play; the joint should resist rotational force when tested by hand.
