Alright PC builders and upgraders, if you're working with M.2 SSDs or other small components, these mounting screws are an absolute lifesaver. You get 50 pieces in the pack, which is way more than you'll probably need for one build, but trust me - you'll be glad to have extras when you inevitably drop one or they disappear into that black hole where small screws go. They're M2 size with a 3mm length - exactly what you need for securing NVMe SSDs, WLAN cards, cooling fans, I/O boards, and various laptop components. The Phillips flat head design sits flush with surfaces, and the drive type is standard Phillips so you can use most screwdrivers. They're made from carbon steel with a nickel plating that gives them that durable black finish. The specifications are spot on: about 2mm thread diameter, 3mm total length, 4.5mm head diameter, and 0.8mm head thickness. I've used these for multiple PC builds and laptop repairs, and they fit perfectly every time. The quality is consistent too - no stripped heads or threads that don't match properly. Having a good supply of these on hand saves so much frustration when you're in the middle of a build and realize you're missing the right screws. If you work on computers regularly or even just planning one upgrade, these M.2 screws are one of those small but essential components that make everything go smoothly.
