These short standoffs will let you securely attach compatible HATs to a Pi Zero or Zero W, to make a nice, slim sandwich.
The standoffs have a 3mm screw at one end, which could be used to pass through a Raspberry Pi or other PCB and have a screw attached for a secure fit.
These will only work with HATs with short headers and no bulky components on the underside - for most HATs you're probably better off with 10mm standoffs.
- 4 x 7mm M2.5 M-F standoff (7mm standoff + 3mm screw = 10mm total length)
- 5 x M2.5 5mm screw
