Ssd Screw Size: Why Getting It Right Is Crucial

The screw size for a Crucial SSD depends on the model. For example, the screw size for the M.2 SSD Crucial MX200 is M2x3mm, while the screw size for the 2.5 SSD Crucial MX500 is M3 3mm. The Crucial M4 SSD requires metric M2 screws, while the Crucial 256 SSD requires #6-32 screws, either 6-32 x 5mm or 6-32 x 4mm. The Crucial P5 1TB PCIe M.2 2280 SSD requires a screw to hold it down, but this is not included with the drive.

M.2 SSD mounting screws

When purchasing M.2 SSD mounting screws, it is important to ensure compatibility with your specific motherboard. Some screws are designed for use with specific brands of motherboards, such as ASUS, Gigabyte, ASRock, or MSI. It is also important to consider the quality of the screws, as they should be made from durable materials to guarantee their longevity.

In addition to the screws themselves, some kits include additional components such as standoffs, washers, and a screwdriver. Standoffs are spacers that provide distance between the M.2 SSD and the motherboard, ensuring a secure fit. Washers are used with screws to distribute the load and can also provide additional stability.

When installing M.2 SSD mounting screws, it is recommended to use a magnetic screwdriver for ease of installation, especially when working with tiny screws.

Screws for 2.5 SSD

If you have recently purchased a 2.5-inch SSD for your desktop and need certain screws to mount it to your case, then you are in the right place.

There are two common PC screw sizes, and you will need the finely threaded one. The M3 screw is a metric screw with a nominal diameter of 3mm and a standard coarse thread pitch of 0.5mm. M3 screws are the second most common screw found in PCs and are commonly used to secure optical disc drives, 2.5-inch HDDs, and SSDs. They typically accept a #1 Phillips screwdriver tip.

You can purchase M3 screws in various lengths, ranging from 1-20mm. You can try hardware stores, but be aware that they may only have screws that are the right width but too long. You can also order an SSD mounting bracket that will come with the correct screws.

If you are unable to find M3 screws, old optical drive screws or HDD screws from laptops should also work.

Screws for SSDs without mounting screws

If you have purchased a Crucial P3, P3 Plus, or P5 Plus series drive, screws to secure your M.2 SSD to your motherboard will be included. Typically, the screw, as well as a standoff, will be preinstalled in a ready-built system or included in the packaging for your motherboard if built by the end-user. However, M.2 screw sizes are not standardized across all systems, so if the included screw does not fit, you will need to contact the system or motherboard manufacturer to determine the correct size. They will be able to confirm the model and exact part specifications, possibly providing options for direct replacement or details on what to purchase from third-party sources. A common size for replacement screws is M2x0.4mm.

If you are mounting a 2.5 SSD, the screw size is likely M3 3mm. This is the same size as the screws used for old optical drives and HDDs in laptops.

If you are unable to find the correct screw size or purchase the correct screws, there are alternative solutions to mount your SSD. Some people suggest using double-sided tape, although this is not recommended if your PC is moved around frequently. Picture mounting putty is another option, as SSDs do not have moving parts.

Screw sizes for different SSDs

The screw size for SSDs depends on the type of SSD and the computer case. SSDs are typically either 2.5-inch or 3.5-inch drives, and the screw size will depend on the size of the drive and the specific case it is being mounted in.

For a 2.5-inch SSD, the most common screw size is M3. These screws have a nominal diameter of 3 millimetres and a standard coarse thread pitch of 0.5 millimetres. M3 screws are typically used for securing optical disc drives, 2.5-inch hard disk drives (HDDs), and solid-state drives (SSDs). They usually accept a #1 Phillips screwdriver tip.

For a 3.5-inch SSD, the most common screw size is 6-32. These screws are larger than M3 screws and are used for 3.5-inch hard drives, power supplies, securing expansion cards, and case panels.

It's important to note that SSDs may also use M.2 screws, which are not standardised across all systems. The screw size for M.2 SSDs will depend on the motherboard or system manufacturer. A relatively common size for replacement M.2 screws is M2x0.4mm.

When installing an SSD, it's important to use the correct screw size to prevent damaging the hardware. If you are unsure about the correct screw size, it is recommended to consult the manufacturer or a computer forum for advice.

Screw alternatives for SSDs

If you're looking for alternatives to screws for mounting your SSD, there are a few options you can consider:

• Adapter Cards: You can attach your SSD to an adapter card that fits in the slots. These adapter cards usually come with the necessary screws and cost around $15-$20. This option is suggested by a user on Tom's Hardware Forum and they mention that it hasn't affected the speed of their NVMe.
• Tape: As SSDs don't have moving parts, you can use tape to mount them. A user on AnandTech Forums recommends using picture mounting putty. Another user on Tom's Hardware Forum suggests using tape that can withstand some heat, such as electrical tape or Scotch tape. They advise catching the edge of the board and trying not to cover the chip to avoid trapping heat, as SSDs run hot.
• String: A user on AnandTech Forums mentions using string as a valid option for mounting an SSD.
• Chewing Gum: Although not recommended by another user, a Super Moderator on AnandTech Forums suggests using chewing gum as a mounting alternative.
• Heatsinks: The same user on Tom's Hardware Forum who suggested using tape also recommends buying heatsinks for your SSD. They mention that heatsinks are cheap and can help with the heat generated by SSDs.
• 3D Printing: If you have access to a 3D printer, you can try printing custom standoffs or spacers for your SSD. A user on Reddit mentions that they 3D printed stands of various heights to find one that fit their SSD.

It's important to note that while these alternatives may work, using the appropriate screws is still the recommended method for mounting SSDs.
