## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=GB-3422-0125-0020:1` (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-3422-0125-0020:1.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)

## Description

Punch up the precision—and the speed!—with this GT2 Pinion Timing Pulley! Fine-toothed to drive 6mm wide GT2 belt, this pulley’s dual-material construction rocks steel where you need it—in its flange, and the barrel that houses the threads of its set-screw hole—while using aluminum in the remainder of the pulley.

The 1/8" bore matches perfectly with the 1/8" D-shaft on a 5000 Series motor. The M4 set-screw—which features the thread-locking magic of a nylon patch—interfaces securely with the flat of the D-shaft, and it’s driven via a torx drive that allows you to put gorilla-level torque on the screw! (You might wonder where you’ll find a Torx key—and don't worry! A T8 Torx key is included so that you don't need to rifle through your toolbox.)
