- Thread M2 = the threaded shank is 2 mm across. Hold the old screw against a ruler or use calipers; M2, M2.5 and M3 look alike but do not swap.
- Length 4 mm is measured from under the head to the tip. Too long can hit parts behind the hole.

M2 x 4mm Phillips Wafer Head Screw for Custom Mechanical Keyboard Build - Pack of 100
Need a reliable supply for ongoing repairs? This listing is for one hundred (100) M2 x 4mm Phillips wafer head black oxide carbon steel screw, sized specifically for use in Custom Mechanical Keyboard Build. Sold in a pack of 100 — ideal for bulk repairs, service shops, and keeping your toolkit well-stocked.
Why the Right Screw Matters
Using the wrong screw size can cause permanent damage to your hardware. A screw that is too long can puncture components, crack motherboards, or push through chassis. A screw too short will not hold, and the wrong thread diameter will strip threads in their seats and ruin standoffs.
- Wrong length: punctured PCBs, cracked housings, broken battery cells
- Wrong diameter: stripped threads in standoffs and inserts
- Wrong drive type: cammed-out heads and unrecoverable fasteners
- Wrong finish: corrosion and rust over time
What You Get
- Quantity: 100 screws per pack
- Thread: M2 (metric coarse, 0.4mm pitch)
- Length: 4mm under the head
- Head style: Phillips wafer head
- Material: carbon steel with black oxide finish
Compatibility
This M2 x 4mm screw is commonly used in:
- Custom Mechanical Keyboard Build
- Compatible models: Custom Mech Keyboards (Universal)
- Other equipment using M2 x 4mm Phillips wafer head fasteners
Specifications
- Screw size: M2 x 4mm
- Thread diameter: 2mm
- Thread pitch: 0.4mm (metric standard)
- Length: 4mm
- Head: flat / Phillips drive
- Material: carbon steel
- Finish: black oxide
- Standard: Metric
Important: Do not mix metric M-sizes. M2 and M2.5 look similar but have different thread diameters and pitches - using the wrong one will cross-thread or strip the seat. Always verify the original screw's diameter and length before installing.
Fits these models
Devices whose service manuals, parts lists or manufacturer specifications call for an M2 x 4mm metric screw at the position shown. The thread and length match; check that the screw you are replacing also has a wafer head (low profile, flat underside).

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.
