The Perfect Screw Size For Raspberry Pi Zero

The Raspberry Pi Zero uses M2.5 screws for mounting. The mounting holes are 2.75mm in diameter, and the screw thread is 0.45mm. While it is possible to enlarge the mounting holes to accommodate larger screws, such as M3 screws, it is important to be careful not to crack the PCB.

M2.5 screws are used for the Pi Zero W

M2.5 screws are available in a variety of materials, including brass, stainless steel, and nylon. They are available in different lengths, such as 5mm, 6mm, 8mm, 10mm, 11mm, 12mm, and 15mm. The screw thread is M2.5 (2.5mm) with a thread pitch of 0.45mm.

M2.5 screws can be purchased individually or as part of a kit that includes standoffs, spacers, and nuts. These kits are designed for DIY projects and are useful for building Raspberry Pi cases or stacking multiple Raspberry Pi units. The kits typically include a range of M2.5 screws and other components in a plastic storage box.

When purchasing M2.5 screws for the Pi Zero W, it is important to consider the length of the screws and the material they are made of. The screws should be long enough to securely mount the Pi Zero W to the desired surface or enclosure. The material of the screws should be compatible with the Pi Zero W and provide the necessary strength and durability.

M3 standoffs are used for the Pi Zero

M3 standoffs are used to attach the motherboard to the case chassis of a computer. The case material is usually a conductive metal, and attaching the motherboard directly to it can cause a short circuit. M3 standoffs are therefore used to provide a margin of space between the motherboard and the case to keep the multiple solder points from grounding and short-circuiting.

The M3 is a metric screw specifying a nominal diameter of 3 millimetres (0.12 in); and a standard coarse thread pitch defined as 0.5 millimetres (0.020 in). The M3 is the second most common screw found in PCs. It commonly appears in many lengths from 1 to 20 mm. Nearly every brand-new computer case comes with a bag of M3 screws.

M3 standoffs are also compatible with the REV DUO System and are perfect for raising one assembly above another or as linkages when paired with male ball joint rod ends.

M2.5 screws are used for the Raspberry Pi 4, 3, and Pi Zero

The Raspberry Pi Zero, for example, has four mounting holes that require M2.5 screws. While it is possible to use 3D printing to create these screws, it is not recommended due to the precision and fragility required. Instead, purchasing a kit of M2.5 screws, nuts, and standoffs is a more reliable and cost-effective option.

The same M2.5 screw size is applicable to the Raspberry Pi 4 and 3. It is important to note that some users have reported success in using M3 screws by carefully enlarging the mounting holes, but this may void warranties and requires caution to avoid damaging the PCB.

When purchasing screws for the Raspberry Pi, it is essential to consider the specific model and revision, as the mounting hole sizes and screw requirements may vary slightly between versions.

M2.5 screws are used for the Pi 1 B+

M2.5 screws are commonly used for mounting Raspberry Pi boards. They are available in various materials, including brass, stainless steel, and nylon. The screw thread for M2.5 screws is 2.5mm, with a thread pitch of about 0.45mm.

When purchasing M2.5 screws for the Pi 1 B+, it is important to consider the length of the screws. The screws should be long enough to securely mount the board but not so long that they protrude or interfere with other components. It is also essential to ensure that the screws are made of high-quality materials and have consistent thread tolerances to avoid issues during assembly.

In addition to the screws themselves, it is recommended to use standoffs and nuts to securely mount the Pi 1 B+. Standoffs create space between the board and the mounting surface, allowing for airflow and heat dissipation. They also ensure that the screws do not put excessive pressure on the circuit board. Nuts help secure the screws in place and provide stability to the assembly.

M2.5 screws are used for the Pi 1 B (rev 2)

M2.5 screws are used to mount the Raspberry Pi to your project. The Raspberry Pi B+ and Pi 1 B (rev 2) contain mounting holes that are compatible with M2.5 screws. The Raspberry Pi B+ has four mounting holes, while the Pi 1 B (rev 2) has two.

M2.5 screws are available in various lengths, such as 5mm, 6mm, 8mm, 10mm, 11mm, and 12mm. They are made from materials such as brass, nylon, and stainless steel.

You can purchase M2.5 screws individually or as part of a kit that includes other components such as nuts, spacers, and standoffs. These kits are designed for DIY projects and are useful for building Raspberry Pi cases or stacking multiple Raspberry Pis together.

When purchasing M2.5 screws, it is important to consider the length and material that best suits your needs. The M2.5 designation refers to the screw's diameter, so you will also need to select the appropriate length for your application.
