LeFix 8 Pack Screws Isolation Grommet Mute Mounting for HP 3.5" 3.5inch HDD DC5800 DC7800 DC7900 6005 6200 6300 Z200 6000 8000 8100 8200 8300 Z400 Z200 Z210 Z220 Z600 450712-001 (8 Screws)

I was recommended these screws for adding 3.5" drives to my refurb'd HP EliteDesk 800 G3. I'm running BlueIris so I needed to install two surveillance drives. The computer did not come with the screws. After using these screws the drives were able to snap into place. Contains screws for two 3.5" hard drives.

Worked great for mounting two 3.5" hard drives in the existing bays for HP Elitedesk 800 G5 SFF.

Wanted to install 2, 3.5 inch hdds in an old HP elitedesk G3 sff desktop for a NAS. It did not come with screws to install, these were a perfect fit. Initially did not understand how to use them, but once I figured it out, the disks snapped into place with the clips on the frame.

These are perfect for mounting my hard drive in the HP EliteDesk 800 G4 SFF computer.

Works as advertised and I am happy with the quality of it. Please be prepared for a very slow arrival date, it takes weeks to receive your order. I would and already have ordered again from them.I used these screws to install a 3.5" HDD into an HP Elitedesk 800.

Worked beautifully for HP Elitedesk 800 G3 SFF small form factor. Fit 3.5 drive threads great. Solidly snapped into place in the case. Better than stock screws because of the isolation grommet.

In order to add a new 3.5" HDD to my HP ProDesk 600 G2 SFF I needed these exact screws. The screws that were supplied inside the server only worked on the secondary 3.5" bay. The primary 3.5" bay needed these screws which are much wider so the drive can slide into the slots holding the primary 3.5" drive in the bay. The drive slid into the appropriate slot and clicked securely into place. I was searching for info on the reason my primary drive didn't fit in the primary drive slot but my secondary drive did fit in the secondary drive slot and had no luck. I figured my explanation here might help someone else. On the HP ProDesk 600 G2 SFF machine, the primary and secondary 3.5" drives require different screws. Go figure. I also have a primary 2.5" SSD which I did not mess with and have no idea what screws that one needs.

these screws are too big for the hp prodesk 400 g7, I would look elsewhere if you're trying to find HDD screws for that model.
