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.

Overview

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.

Using 11 mm aluminum standoffs with 6mm-long threads to mount an A-Star 32U4 Robot Controller on a Raspberry Pi 2 Model B.

In particular, two of these standoffs can be used to mount a Raspberry Pi on a Balboa 32U4 robot:

Balboa 32U4 Balancing Robot with 80×10mm wheels and a Raspberry Pi 3 Model B.

Note that the version of the 11mm standoffs with longer, 6mm threads do not work well with the Balboa because the threads hit the robot chassis.

Other sizes

We also carry 18.6mm-long standoffs that match the height of our extra-tall 2×20 female headers and can be used to mount expansion boards so that they clear all of the components on the Raspberry Pi Model A+ and Model B+ as well as the Raspberry Pi 2 Model B and Raspberry Pi 3 Model B.

In addition to these specialized standoffs, we carry standoffs in a variety of standard imperial lengths and thread types:
