From precision electronics to structural steel connections, these nickel‑plated pan head self‑tapping screws combine high strength with a polished, corrosion‑resistant finish. Stamped from carbon steel and treated with a bright nickel plating, each screw provides reliable resistance to oxidation and mild humidity — ideal for indoor environments, automotive applications, and light‑duty outdoor projects. The sharp, self‑tapping thread cuts its own path into sheet metal, wood, plastic, and composites without a pilot hole in most thin materials, speeding up every assembly. A classic pan head sits flush with a clean, rounded appearance, while the Phillips drive ensures a cam‑out‑resistant grip. Covering the entire micro‑range from M1 to M3 in eight precise diameters, this selection gives you the exact size for everything from eyeglass repair and RC models to appliance panels and steel frame brackets.
| Size | Thread Diameter | Typical Lengths (mm)* | Head Style | Drive | Material & Finish |

| M1 | 1.0 mm | 3 – 6 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M1.2 | 1.2 mm | 3 – 8 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M1.4 | 1.4 mm | 3 – 10 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M1.7 | 1.7 mm | 4 – 12 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M2 | 2.0 mm | 4 – 16 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M2.3 | 2.3 mm | 5 – 20 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M2.6 | 2.6 mm | 6 – 25 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |
| M3 | 3.0 mm | 6 – 30 | Pan Head | Phillips | Carbon Steel, Bright Nickel Plated |

Nickel plating provides better corrosion resistance in damp and mildly acidic environments than plain zinc. It also keeps a brighter, more polished look that doesn’t fade as quickly, making it a popular choice for visible fasteners in electronics, appliances, and automotive interiors.
Yes — the carbon steel is hardened for strength, and while the smaller diameters (M1–M2) are more common in precision work, the larger sizes (M2.6–M3) are often used for light‑gauge steel framing, brackets, and industrial connections where a self‑tapping fastener is preferred.
In thin sheet metal (up to about 1 mm) and soft plastics, you can often drive them directly. For denser materials or thicker steel, a small pilot hole — roughly 80% of the thread diameter — will make driving easier and keep the thread from stripping.
The smallest screws (M1–M1.4) require a #0 Phillips bit. M1.7–M2.3 typically use a #1 bit, while M2.6–M3 work with a #1 or #2 bit. A quality precision screwdriver set will provide the best engagement.
