## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3202-0001-2503:1` (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/GB-3202-0001-2503:1.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.)

## Description

Isolate the radial load from your servo with a ServoBlock®! This version is designed for a standard size servo with an H25T output spline. It has an 8mm diameter round shaft onto which you can install an 8mm clamping hub. This allows you to quickly and easily adjust the position of components attached to the hub without requiring disassembly.

The round shaft’s profile provides for the **infinite indexability** of motion components like hubs and couplers, while its length allows for more **axial adjustment** along the shaft for the attached component. The overall “block” structure also facilitates **robust support of the servo shaft** by maximizing the distance between the servo-to-shaft fastening location and the bearing supporting that shaft. And thanks to the side mounts with holes on the goBILDA® 16mm square patterns, this ServoBlock® boasts **versatile attachment options**.
