🔩 Pan Head Self-Tapping Screws – 304 Stainless Steel (M1.2, M1.4, M2)

Small in size, big in corrosion resistance — these Phillips pan head self-tapping screws are precision‑made for delicate jobs where rust is not an option. Stamped from genuine 304 A2 stainless steel, they handle moisture, humidity, and mild chemicals without surface coating failure, making them ideal for electronics enclosures, outdoor sensors, RC models, and marine instruments. The classic pan head sits flush and clean, while the sharp self‑tapping thread cuts its own path into thin sheet metal, plastic, wood, and fiberglass — no pre‑tap, no pilot hole required in most materials. BRT Fasteners supplies three of the most requested micro‑diameters: M1.2, M1.4, and M2, each available in a range of short lengths to match your exact assembly thickness. If precision, appearance, and long‑term reliability are on your checklist, these screws deliver.

❓ Frequently Asked Questions – Micro Self-Tapping Screws 304

🔸 Can these really be used outdoors without rusting?

Yes. 304 stainless steel is specifically designed to resist corrosion in wet and mildly corrosive environments. These screws won’t red‑rust like carbon steel. For permanent saltwater immersion, you’d step up to 316, but for rain, humidity, and general outdoor use, 304 delivers excellent longevity.

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

In very thin sheet metal (up to about 0.8 mm), you can often drive them straight in. For thicker or harder materials, a small pilot hole — around 80% of the screw diameter — will make driving easier and prevent snapping the screw. A 1 mm drill bit works well for M1.2, a 1.1 mm drill bit for M1.4, and a 1.6 mm drill bit for M2.

🔸 Which Phillips driver should I use?

These tiny screws require a #0 Phillips bit for M1.2 and M1.4, and a #0 or #1 for M2, depending on the exact recess. A precision screwdriver set with micro bits will give you the best fit and help avoid cam‑out.

🔸 Are these really self-tapping — even in metal?

Yes. The thread geometry is designed to form or cut its own mating thread in thin sheet metal, plastic, and wood. The tip geometry helps them bite into the material as soon as you apply gentle pressure. For very hard metals, a pilot hole is still recommended, but in most hobby and electronics applications, they tap their own path without issue.

🔸 What’s the difference between the pan head and the round head on these?

Although often described interchangeably, a pan head has a slightly flattened top with a wider bearing surface compared to a classic round head. The provided dimensions (dk and k) match a pan head profile, which gives a cleaner finish on flat surfaces while still providing enough engagement for the Phillips driver.
