6/32#6-32 x 1/4 inch Flat Head Screw for 3.5 inches Hard Drive Hot Swap Caddy TRAY (pack of 50)

These screws I used for R720XD 3.5" HDD caddies. They fit perfectly. No issues. I even compared them using calipers and they are perfect.

Really useful set of hard drive screws, I always seem to throw the ones away that I receive with drives as most of my needs are for NAS with plastic retainers, but sometimes I need these screws!

They’re screws. They fit hard drives. In that respect they are great. They don’t fit QNAP hot swap drive trays due to the head being too large. The search goes on

Just as advertised and a very quick delivery.

they fit flawlessly and right sort of counter sink for the asustor as5002t nas drive caddies

I saw another review from someone reported that they wouldn't fit his model QNAP. Must be a different drive tray design, as I had no trouble with my 879. Good quality product.

They're #6/32 thread okay, and they fit the imperial sized mounting holes on 3.5" (and 5") hard drives. Unfortunately the heads are too small to fit the drive sleds on Hewlett Packard GEN8 or later servers. (Previous sleds used button/pan head). The problem is that when they're tightened down the countersunk head contacts the drive before the counterbore in the mounting hole, so they rattle. You could get around this with a small fibre washer, or you could ignore it. The correct screws have wider flatter heads. However, the correct screws are really difficult to find except as spare parts from the server manufactures, in which case they're crazy expensive. So I'm keeping these and I'll live with the rattle. Note that 2.5" drives are bored for standard M3 which you can get anywhere, and most CD-ROM and similar drives are the same. It's only 3.5" Winchesters that are the problem.

Picked up two packs of these for mounting scsi drives into saf-te enclosures for a raid array I'm building. Great quality for the price... Used a pack so far and not had any that were not usable, like you usually get with cheap/poorly made bolts, screws etc! ***Recommended***

perfect fit on my seagate barracuda 2TB hdd. using it for my own NAS. good product

Ces vis sont parfaitement adaptées pour fixer des disques durs dans des boitiers destinés à aller dans un serveur Supermicro. Rien à redire : elle sont bien usinées et remplissent parfaitement leur rôle.

Le viti risultano robuste e di buona fattura. Purtroppo non compatibili con le slitte per HD del NAS QNAP TVS-463

Alles bestens, empfehlenswert!

exactly what I needed! good price, fast delivery! I had asked at a local computer store, but they did not have ANY?!?
