- Thread M1.4 = the threaded shank is 1.4 mm across. Hold the old screw against a ruler or use calipers; M2, M2.5 and M3 look alike but do not swap.
- Length 3 mm is measured from under the head to the tip (flat heads sit flush, so compare like with like). Too long can hit parts behind the hole.

M1.4 x 3mm Black Wafer Head Phillips Machine Screws (2.5mm thin flat head)
Metric M1.4 x 0.3mm machine screws, 3mm long, with a wafer head: a wide, thin, flat-topped head (2.5mm across) that sits on the surface instead of sinking into a countersink, like the low-profile screws used inside laptops and electronics. Black carbon steel, Phillips drive. Packs of 10 / 50 / 100.
Why the Right Screw Matters
Match three things: the thread (M1.4), the length and the head. A countersunk (cone) screw in a flat seat sits loose; a pan head can be too tall for a tight cover. A wafer head spreads the load over a wide, thin bearing surface and keeps the profile low.
How to Measure
- Thread: M1.4 measures about 1.3-1.4mm across the threads; pitch 0.3mm (metric coarse).
- Length: for a wafer (non-countersunk) head, measure from under the head to the tip: 3mm.
- Head: flat, thin and 2.5mm across; flat underneath.
Typical Uses
- Smartphone internal brackets, board shields and sub-boards (M1.4 is the common Android phone thread)
- Smartwatches, compact cameras and small handheld electronics
- Micro electronics, PCB and model building
No specific device model is claimed: compare with the screw you removed (thread, length and head) before ordering.

How to Choose the Correct Screw
How to Choose the Correct Screw
Selecting the correct screw is important for proper fit, strength, and long-term reliability. Before ordering, confirm the following:
Screw Size (Diameter)
Measure the outer thread diameter of the screw. Metric screws are labeled in millimeters, such as M2, M2.5, or M3.
Length
Measure from under the head to the tip of the screw unless otherwise specified by the head style.
Thread Type
Ensure the thread matches the receiving material. Most electronics and hardware applications require metric machine threads rather than self-tapping threads.
Head Type
Confirm the head style needed for proper seating, such as flat head, pan head, or button head.
Drive Type
Match the drive type (Phillips, Torx, Hex, etc.) to the tools you plan to use and the torque requirements of the application.
Material & Finish
Choose the appropriate material and finish based on strength, corrosion resistance, and environmental conditions.
If you are replacing an existing screw, we recommend removing one and comparing the diameter, length, and head type directly before ordering to ensure a proper fit.
Frequently Asked Questions
Frequently Asked Questions
Are these screws metric or imperial?
These are metric screws. Metric screws are measured in millimeters and are commonly used in electronics, laptops, keyboards, and precision hardware.
How is screw length measured?
Screw length is measured from under the head to the tip of the screw, unless otherwise specified by the head style.
Will these screws fit laptops, keyboards, or electronics?
Yes. These screws are commonly used in laptops, mechanical keyboards, SSD mounting, cameras, and other electronic devices. Always verify size and thread type before ordering.
Can these screws be used as replacements?
Yes. These screws are ideal replacements for lost or stripped screws in compatible devices. We recommend comparing one existing screw for best fit.
What tools are required to install these screws?
Installation typically requires a matching screwdriver based on the drive type, such as Phillips, Torx, or Hex. No special tools are required.
