M1.4 Phillips Flat Head Carbon Steel Machine Screws (Multiple Lengths & Finishes)
M1.4 Phillips Flat Head Carbon Steel Machine Screws (Multiple Lengths & Finishes) - 3mm / Black is backordered and will ship as soon as it is back in stock.
These are Phillips flat head machine screws made from carbon steel in M1.4 size, designed for precision fastening applications in miniature electronics, eyewear, small instruments, watches, and micro-mechanical assemblies.
M1.4 screws occupy a specialized position in the micro-fastener range, sitting between M1.2 and M1.6 sizes. This precise sizing is frequently specified in eyeglass frames, small electronic devices, watch components, precision instruments, and delicate assemblies, yet M1.4 screws are extremely difficult to source locally and are often confused with M1.2 (too small) or M1.6/M2 (too large) sizes. Using M1.2 screws will result in loose connections with excessive play that cannot properly secure components, while forcing M1.6 or M2 screws will cross-thread and permanently damage the delicate threaded holes in plastic frames, aluminum housings, or precision-machined parts. The flat head countersunk design is critical for applications requiring flush mounting where even minimal screw head protrusion would interfere with adjacent components or create an unprofessional appearance in visible applications like eyewear and consumer electronics.
This exact M1.4 screw set solves these problems by providing authentic metric M1.4 x 0.3mm thread pitch in multiple lengths to accommodate various material thicknesses and precision assembly applications. The Phillips flat head design allows the screw to sit flush or below the surface when used with countersunk holes, creating clean, professional assemblies without any protrusion. Available in both black oxide and zinc-plated finishes, these screws offer corrosion resistance appropriate for their application while maintaining the ultra-precise tolerances needed for reliable thread engagement in miniature components. The carbon steel construction provides excellent strength-to-size ratio despite the small dimensions, preventing stripping during installation while ensuring durable, long-lasting fastening in delicate applications.

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.
