M.2 Screws: The Ultimate Guide to Finding the Right Size

Q: What is the most common M.2 screw size?

The most common M.2 screw size for securing an SSD to a motherboard is M2x3mm, which means it has a 2mm thread diameter and a 3mm length. While this is the standard, some motherboards may use slightly shorter or longer screws like M2x2.5mm or M2x4mm.

Q: Can I use an M.2 SSD without its screw?

No, it is highly discouraged. An M.2 drive will not be properly seated in the connector without the screw, leading to a poor connection, risk of it falling out, and potential physical or electrical damage. Always use the screw to ensure stability and proper operation.

Q: Do new M.2 SSDs come with screws?

Typically, no. The necessary M.2 screws and standoffs are almost always included with the motherboard, not the M.2 drive itself. If you bought your motherboard new, check the box for a small bag labeled 'M.2'.

Q: What screwdriver do I need for an M.2 screw?

You will need a small Phillips head screwdriver, usually a #0 or #1 size. A magnetic tip is extremely helpful for handling these tiny screws without dropping them inside your PC case.

Q: Are M.2 screws and laptop screws the same?

Sometimes, but not always. Many laptops use M2 screws for various components, so you might find a compatible one. However, laptop screw kits can vary widely. It’s best to use a screw specifically designated for M.2 SSD mounting to ensure the correct length and head type.

Q: Are all M.2 standoffs the same?

No. While most have the same internal threading for the M.2 screw, their height and the way they attach to the motherboard can vary between manufacturers. Always use the standoff that came with your specific motherboard.

Q: Where can I find the M.2 screw that came with my motherboard?

The M.2 screw and standoff are usually in a small, clearly labeled plastic bag inside your motherboard box. If you can't find it, it may have come pre-installed on the motherboard itself, sometimes underneath a heat sink.
