❓ Frequently Asked Questions – Small Self‑Tapping Screws

🔸 Is the length measured including the head?

No. All lengths listed are the thread length only, measured from directly under the pan head to the tip. This makes it simple to match the screw to the exact thickness of the material you’re fastening.

🔸 Do I need to drill a pilot hole for these tiny screws?

In thin sheet metal (up to about 1 mm) and soft plastics, you can usually drive them straight in. For thicker metal or very hard plastics, a small pilot hole about 80% of the thread diameter makes driving easier and prolongs thread life.

🔸 Will the black zinc finish wear off or rust?

Black zinc provides good corrosion protection for indoor and light outdoor use. It’s not marine‑grade, but it will resist everyday humidity and moisture well. Prolonged exposure to wet conditions may cause surface discoloration over time.

🔸 Which Phillips driver bit should I use for each size?

Sizes M1.4–M2 usually require a #0 bit, M2.3–M3 use #0 or #1 (test for best fit), and M3.5–M4 use a #1 or #2 bit. Using a sharp, correctly sized bit prevents cam‑out and keeps the screw head in good condition.
