# Aluminum Standoff for Raspberry Pi: 11mm Length, 4mm M2.5 Thread, M-F (4-Pack) **Type:** Product page · **SKU:** POLOLU-2713 · **Brand:** [Pololu](https://core-electronics.com.au/brands/pololu-australia) **Page:** https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-11mm-length-4mm-m2-5-thread-m-f-4-pack.html ([markdown](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-11mm-length-4mm-m2-5-thread-m-f-4-pack.html.md)) 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... ## Pricing - **Price:** $5.45 (inc GST) — $4.95 AUD, exc GST - **Quantity discounts:** 10+ $4.75 (exc GST) · 25+ $4.61 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 5 today, and up to 250 more in 4–7 days. ## Description These aluminum hexagonal standoffs are just the right size for mounting expansion PCBs or HATs with [standard-size female headers](https://core-electronics.com.au/stackable-0-100-female-header-2x20-pin-straight.html) on a [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html). 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. Pololu carry [**M2.5 nuts**](https://core-electronics.com.au/machine-hex-nut-m2-5-25-pack.html) and [**6 mm M2.5 screws**](https://core-electronics.com.au/machine-screw-m2-5-6mm-length-phillips-25-pack.html) separately. In particular, two of these standoffs can be used to mount a Raspberry Pi on a [Balboa 32U4 robot](https://core-electronics.com.au/pololu-balboa-32u4-balancing-robot-kit-no-motors-or-wheels.html): Note that the version of the 11mm standoffs [with longer, 6mm threads](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-11mm-length-6mm-m2-5-thread-m-f-4-pack.html) do not work well with the Balboa because the threads hit the robot chassis. **Other sizes** Pololu also carry [18.6mm-long standoffs](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-18-6mm-length-6mm-m2-5-thread-m-f-4-pack.html) that match the height of Pololu's [extra-tall 2×20 female headers](https://core-electronics.com.au/stackable-0-100-female-header-with-extra-0-3-spacer-2x20-pin-straight.html) and can be used to mount expansion boards so that they clear all of the components on the [Raspberry Pi Model A+](https://core-electronics.com.au/catalog/product/view/sku/POLOLU-2760) and Model B+ as well as the Raspberry Pi 2 Model B, Raspberry Pi 3 Model B, and [Raspberry Pi 3 Model B+](https://core-electronics.com.au/catalog/product/view/sku/POLOLU-2797). In addition to these specialized standoffs, Pololu carry standoffs in a variety of standard imperial lengths and thread types: **People often buy this product together with:** | [![0.100" (2.54 mm) Female Header: 2x20-Pin, Straight](https://core-electronics.com.au/attachments/localcontent/0J5996_2940251c81.jpg)](https://core-electronics.com.au/0-100-2-54-mm-female-header-2x20-pin-straight.html) | [0.100" (2.54 mm) Female Header: 2x20-Pin, Straight](https://core-electronics.com.au/0-100-2-54-mm-female-header-2x20-pin-straight.html) | |---|---| | [![Aluminum Standoff for Raspberry Pi: 18.6mm Length, 6mm M2.5 Thread, M-F (4-Pack)](https://core-electronics.com.au/attachments/localcontent/0J7096_2719ffb75b.jpg)](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-18-6mm-length-6mm-m2-5-thread-m-f-4-pack.html) | [Aluminum Standoff for Raspberry Pi: 18.6mm Length, 6mm M2.5 Thread, M-F (4-Pack)](https://core-electronics.com.au/aluminum-standoff-for-raspberry-pi-18-6mm-length-6mm-m2-5-thread-m-f-4-pack.html) | |---|---| | [![Machine Hex Nut: M2.5 (25-pack)](https://core-electronics.com.au/attachments/localcontent/0J7091_4162e8845d.jpg)](https://core-electronics.com.au/machine-hex-nut-m2-5-25-pack.html) | [Machine Hex Nut: M2.5 (25-pack)](https://core-electronics.com.au/machine-hex-nut-m2-5-25-pack.html) | |---|---| **Dimensions** | Length: | 11 mm | |---|---| | Weight: | 0.3 g[1](https://core-electronics.com.au/#note1) | **General specifications** | Gender: | Male-Female | |---|---| | Thread type: | M2.5 | | Thread length: | 4 mm[2](https://core-electronics.com.au/#note2) | **Notes:** 1 Per standoff. 2 Male thread; female thread depth is 6.35 mm. ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/i/m/image_5455.jpg)
