HomeBase 3 storage upgrade
The HomeBase 3 holds a 2.5-inch SATA SSD or HDD with M3 x 3mm screws. The 3mm length matches the HomeBase 3 drive mounting, so the drive is held without the screw reaching into the drive housing.
How to check the size in 30 seconds
- Thread: M3 means the threaded shank is 3 mm across; M2.5 is 2.5 mm. They look alike, so hold the old screw against a ruler or use calipers.
- Length: measure from under the head to the tip.
- Head: our smart-home screws are Phillips flat head (low profile), black oxide carbon steel.
Not sure? Send us a photo of the screw next to a ruler and your device model before you order.
