They keep parts spaced 18.6 mm apart, which is... ## Pricing - **Price:** $6.50 (inc GST) — $5.91 AUD, exc GST - **Quantity discounts:** 10+ $5.67 (exc GST) · 25+ $5.49 (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. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-1953:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/POLOLU-1953:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description | [ ![](https://core-electronics.com.au/attachments/localcontent/0J7686_147904b8fbe.jpg) ](https://core-electronics.com.au/attachments/localcontent/0J7686_89973f121a4.jpg) | |---| These aluminum hexagonal standoffs 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 PCBs and HATs 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). The body of each male-female standoff is 18.6 mm long by 4 mm wide. The male threads extend another 6 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. | [ ![](https://core-electronics.com.au/attachments/localcontent/0J7098_23690e74441.jpg) ](https://core-electronics.com.au/attachments/localcontent/0J7098_40165e457de.jpg) | |---| | Using 18.6 mm aluminum standoffs to mount an A-Star 32U4 Robot Controller on a Raspberry Pi 2 Model B. | **Other sizes** Pololu also carry 11mm-long standoffs that match the height of Pololu's [standard-size 2×20 female headers](https://core-electronics.com.au/stackable-0-100-female-header-2x20-pin-straight.html) and can be used to compactly mount expansion boards to a [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html).
