Made from durable SUS304 stainless steel, this lead screw boasts an Acme thread with a 2mm pitch and 4 starts for enhanced performance. Ideal for those seeking precision and reliability in their 3D printing projects. ## Description Packing list: 1 * T8x8 400mm lead screw 1 * T8x8 brass nut The lead of the thread is 8mm, which means that the nut will move 8mm if the nut turns one circle. The advantages of the lead screw are: Large load carrying capability Compact Large mechanical advantage Precise and accurate linear motion Smooth, quiet, and low maintenance, very suitable for 3D printer z axis. Minimal number of parts So this lead screw is very suitable for 3D printer Z axis, such as Ultimaker and Prusa i3. The screw type of this lead screw is ACME thread. ACME Threads are generally stronger than square threads due to their trapezoidal thread profile, which provides greater load-bearing capabilities. ## Features - Lead screw diameter 8mm, length 400mm, SUS304 stainless steel - Brass nut, with 4 holes for fixing to the machine - Thread: Acme thread - Screw pitch: 2mm; Lead: 8mm - If you want higher accuracy, it is recommended to use the anti backlash nut ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078R2XLXW | | Best Sellers Rank | #84,103 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #12 in Linear Motion Lead Screws | | Brand | ReliaBot | | Color | Silver | | Compatible Groove Diameter | 8 millimeters | | Customer Reviews | 4.6 4.6 out of 5 stars (295) | | Drive System | Screw | | Exterior Finish | Brass, Stainless Steel | | Fastener Size | 8mm | | Fastener Type | Machine Screw | | Finish Types | Uncoated | | Head Type | Flat | | Item Diameter | 8 millimeters | | Manufacturer | ReliaBot | | Material Type | Stainless Steel | | Metal Type | Stainless Steel | | Number Of Items | 1 | | Number of Packs | 1 | | Outside Diameter | 8 millimeters | | Part Number | EU-RZ007-37 | | Screw Head Style | Flat | | Set Name | ReliaBot 400mm T8 Lead Screw and Brass Nut Set | | Set Screw Thread Type | ACME | | Size Name | 400mm | | Thread Coverage | Fully Threaded | | Thread Size | 8 | | Thread Style | Acme | | Thread Type | Acme | | UPC | 663274125949 | | Unit Count | 1 Count | ## Product Details - **Exterior Finish:** Brass, Stainless Steel - **Head Style:** Flat - **Material:** Stainless Steel - **Metal Type:** Stainless Steel - **Thread Size:** 8 ## Images ![400mm T8 Tr8x8 Lead Screw and Brass Nut (Acme Thread, 2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer Z Axis - Image 1](https://m.media-amazon.com/images/I/31C1GO8pNuL.jpg) ![400mm T8 Tr8x8 Lead Screw and Brass Nut (Acme Thread, 2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer Z Axis - Image 2](https://m.media-amazon.com/images/I/31AQbCKZvNL.jpg) ![400mm T8 Tr8x8 Lead Screw and Brass Nut (Acme Thread, 2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer Z Axis - Image 3](https://m.media-amazon.com/images/I/31GC0nLUTUL.jpg) ![400mm T8 Tr8x8 Lead Screw and Brass Nut (Acme Thread, 2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer Z Axis - Image 4](https://m.media-amazon.com/images/I/314jE7M3P+L.jpg) ![400mm T8 Tr8x8 Lead Screw and Brass Nut (Acme Thread, 2mm Pitch, 4 Starts, 8mm Lead) for 3D Printer Z Axis - Image 5](https://m.media-amazon.com/images/I/31yVMPDJxNL.jpg) ## Available Options This product comes in different **Size, Style** options. --- ## 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/56534691-400mm-t8-tr8x8-lead-screw-and-brass-nut-acme-thread](https://www.desertcart.gr/products/56534691-400mm-t8-tr8x8-lead-screw-and-brass-nut-acme-thread) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-11*
