🔩 Flanged Truss Head Self‑Tapping Screws – Bright Nickel & Black Zinc (M2–M4)

Add extra bearing surface to your fastening job with these flanged truss head self‑tapping screws. The wide, flat‑bottomed head with an integrated flange spreads clamp force to stop pull‑through in thin sheet metal, plastic, and wood — often eliminating the need for a separate washer. Available in two distinct finishes, Bright Nickel for a shiny, corrosion‑resistant look or Black Zinc for a discreet, low‑profile appearance, these carbon steel screws blend into any hardware. The sharp, self‑tapping thread cuts its own tight mate as you drive, with no pre‑tap and no pilot hole in most materials. Covering the most‑used small metric diameters — M2, M2.6, M3, M3.5, and M4 — and lengths from 5 mm to 12 mm, this series is a perfect fit for computer cases, laptop repairs, electronics, and light‑duty furniture assembly.

⚙️ Key Features – Flanged Truss Self‑Tapping Screws

  • Flanged truss head design provides a wide bearing surface to resist pull‑through and distribute clamping force
  • Phillips drive recess for a secure, cam‑out‑resistant grip with standard screwdrivers
  • Self‑tapping thread cuts into sheet metal, wood, and plastic without pre‑drilling in most applications
  • Choose between Bright Nickel plating for a shiny, corrosion‑resistant finish or Black Zinc for a dark, matte look
  • Covers five essential metric diameters: M2, M2.6, M3, M3.5, and M4 — exactly the sizes needed for computer and electronics repair
  • Hardened carbon steel construction with smooth, burr‑free threads for consistent holding power
  • Thread lengths from 5 mm to 12 mm to accommodate thin panels, PCB mounts, and small enclosures

❓ Frequently Asked Questions – Flanged Self‑Tapping Screws

🔸 When should I use a flanged truss head instead of a pan head?

The flanged truss head has a larger, flatter bearing surface with a small lip that acts like a built‑in washer. It distributes the clamping load more evenly and prevents the screw from pulling through thin or soft materials. If you’re working with thin sheet metal, plastic panels, or delicate assemblies, this head style gives you a cleaner, stronger hold.

🔸 Which finish should I choose — Bright Nickel or Black Zinc?

Bright Nickel provides a shiny, silver appearance and offers good corrosion resistance. It matches light‑colored hardware well. Black Zinc has a matte, dark finish that blends into black or dark surfaces — popular for electronics, computers, and any place where you want the fastener to be less visible. Both resist mild rust equally well indoors.

🔸 Can I drive these directly into plastic without a pilot hole?

Yes, especially in softer plastics like ABS. The sharp self‑tapping thread will form its own mating thread. For harder or brittle plastics, a small pilot hole is recommended to prevent cracking.

🔸 Which Phillips bit size fits these screws?

M2 and M2.6 use a #0 Phillips bit. M3 and M3.5 typically use a #1 bit, while M4 will use a #1 or #2 bit depending on the exact recess. A clean, properly sized bit will prevent cam‑out.
