I need a length of 440 mm and would probably be getting a 450 and trimming 5 mm off each end. what tool would be** A: An angle head grinder and thin abrasive wheel will go through it just fine. Dip it in water if it gets too hot. Completely tape the carriage to keep out dust. (Don’t take it off.) **Q: What size t nuts do you use** A: Hi, M3 t nuts and hex screws are suitable **Q: Are the holes in the carriage threaded?** A: The holes in the carriage are tapped 3MM. The rail holes are drilled and counterbored for 3MM sockethead cap screws. **Q: Are these bearing blocks pre-loaded?** A: Yes. Only thing i recommend doing is to clean well (i used a automotive part cleaner spray solvent) and lubricate properly when you get them. Mine are still performing flawlessly. ## Customer Reviews ### ⭐ 引っかかる *by H***E on 22 February 2022* 3Dプリンターでの使用目的で購入。特定の場所で引っかかりがありレールが悪いのかとも思いましたが悪い箇所が見つからず、ガイドブロックを分解清掃グリスアップを行いました。そして余計に悪くなるという結末。使用する気が失せて別のメーカーを購入しました。 ### ⭐⭐⭐ With $8 and some time invested, they can be pretty good rails *by N***A on 26 January 2019* ### ⭐⭐⭐⭐⭐ Worth the $$ if you prep them correctly *by O***K on 5 June 2019* --- ## 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.com.ar/products/97279161-iverntech-mgn12-400mm-linear-rail-guide-with-mgn12h-carriage-block](https://www.desertcart.com.ar/products/97279161-iverntech-mgn12-400mm-linear-rail-guide-with-mgn12h-carriage-block) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-11-12*
