uxcell Computer PC Case 3.5-inch HDD 6#-32 Flat Phillips Head Hard Drive Screw 100pcs

You need some hard drive screws? Look no further. Screws came exactly as advertised and in the correct quantity. Standard HDD caddy screws are what you can expect. Would purchase again when the need arises. I wouldn’t expect any durability issues or quality problems from the screws. The screws are all the same.

I read the reviews on these screws which were a little mixed about whether or not they fit QNAP NAS drive sleds. I ordered these in March 2025 and they fit.While installing there were three screws that didn't go in easily across securing 16 drives across my two NAS units.It's possible that some batches are slightly different, but I had a very good experience and the vibrations from my hard drives were significantly reduced.

I bought these specifically to mount 3.5 inch drives in my 3D printed drive mount caddies. The side rails of my caddies measure 1.7 mm (0.07 inches) thick with recessed holes for the side screws. I measured these screws with my micrometer as being 4.6mm (0.18 inches) long, overall. The description listed them as being 5mm (0.2 inches) long, so you cannot rely on that. Even though they were slightly shorter that the description listed, they fit perfectly with my thin, 3d printed caddy rails.They are made of good quality steel. The threads worked smoothly in my disk drive mounting holes.I recommend these for mounting 3.5 inch drives only with drive caddies/rails that have thin walls of either sheet metal or thin 3D printed rails. Be aware that they are shorter than standard 3.5 inch mounting screws that are typically 5.8mm (0.23 inches) long. Keep this in mind when purchasing for your specific application.

Wish the description mentioned these were 3/8" head diameter. I really needed the 1/4" head diameter screws. These screw heads are a bit small for putting Hard Drives in trays. They will work for other parts and I wont return them so I have them handy if/when needed, but I will be on the lookout for ones with bigger heads for putting the drives in the trays. Shipping time was accurate and thank you for that!

They're screws. I mean, how much can one say about screws? They do fit my Dell PowerEdge drive caddies without interfering with insertion/removal.

Does its job!

Precision fit, solidly constructed. The perfect set of screws needed to install an internal HDD.

The screws all fit and were the right size.
