Aluminum Standoff for Raspberry Pi: 11mm Length, 4mm M2.5 Thread, M-F (4-Pack)
These hexagonal male-female aluminum standoffs are intended specifically for use with the Raspberry Pi. They keep parts spaced 11 mm apart, which is just the right height for mounting expansion boards with standard-size female headers, and they have 4mm-long M2.5 threads that are just the right size for the Raspberry Pi’s mounting holes. These standoffs are sold in packs of 4.
These aluminum hexagonal standoffs are just the right size for mounting expansion PCBs or HATs with standard-size female headers on a Raspberry Pi. The body of each male-female standoff is 11 mm long by 4 mm wide. The male threads extend another 4 mm past the standoff body, and the female threads extend at least 6.35 mm into the body. You can easily screw multiple units together to make longer standoffs. The threads are M2.5 on both ends, since this matches the size of the Raspberry Pi mounting holes. We carry M2.5 nuts and 6 mm M2.5 screws separately.
