It looks like it in the picture, but does not say anywhere.** A: yes mine was, they should mention that in the description but be aware, they could change couplers from when I got mine. I'd say get this kit but be ready to get a coupler just in case. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/140226685-300mm-8mm-t8-lead-screw-set-lead-screw-copper-nut](https://www.desertcart.gr/products/140226685-300mm-8mm-t8-lead-screw-set-lead-screw-copper-nut) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-31*
