Popular choice for DIY maker and 3d printer Electrical Specification: * Manufacturer Part Number: MY-17LS16-1504E-310G* Motor Type: External Linear Stepper * Step Angle: 1.8 deg. * Holding Torque: 59.49 oz-in(42 Ncm)* Rated Current/phase: 1.5A * Phase Resistance: 1.6ohms * Inductance: 3.2mH+/-20%(1KHz) Physical Specification: * Frame Size: 1.65 x 1.65 inches(42 x 42 mm) * Body Length: 1.57 inches(40 mm) * Lead Screw Length: 12.21"(310 mm)* Lead Screw Diameter: Φ0.31"( Φ8 mm)* Lead /Step: 0.0016"(0.04 mm)* Lead/Revolution: 0.315"(8 mm) * Number of Leads: 4 * Lead Length: 39.37 inches(1000 mm)* Weight: 13.76oz(390 g) Connection: Red(A+), Blue(A-), Black(B+), Green(B-) Packing List: 1 x NEMA 17 stepper motor with 310mm lead screw 1 x 39.37" motor wire 1 x Brass nut Review: Motor is taller - +The lead screw is straighter than my lead screw coupler combo. +The motor includes a data sheet. +Arrived double boxed. -The nut squeaks. The motor is taller than my original motor, so plan for that. Review: As expected - Quality seems on-par with the StepperOnline motors I've purchased. Lead screw is straight enough in both of the motors I got. I don't have an accurate way to measure it but I'd estimate maybe 0.25mm of runout at the tip of the screw. One thing to note is that the nuts are TAPPED for M3 screws, they're not M3 through-holes. This won't work with the majority of 3D printer designs if that's what your intending them for. The description doesn't specify this, but the photo does clearly show threads in those holes and apparently I was just too lazy to pay attention. Do yourself a favor a buy a set of Delrin nuts anyway, for this or any other lead screw stepper. They'll be quieter, never need lubricating, and the lead screw will never wear out. ## Features - 310mm Tr8x8 Nema 17 stepper motor, up to 59.49oz-in(42Ncm) holding torque.

Good stepper with plenty of torque *by Y***G on November 23, 2022* Very pleased with this combo. Form factor of the nut is convenient as it's a drop in replacement for 8mm pitch lead screws. The lead screw is straight -- I got 2 -- a couple of weeks apart and both are perfect. The nut has m3 tapped holes, so it's easier to use it with different machines. ## Frequently Bought Together - 310mm Tr8x8 Lead Screw Nema 17 Integrated Linear Actuator Stepper Motor with External Brass Nut 1.5A 59oz-in for RepRap Prusa i3 3D Printers Z Axis CNC - Arduino Uno REV3 [A000066] --- ## 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.cy/products/153827255-310mm-tr8x8-lead-screw-nema-17-integrated-linear-actuator-stepper](https://www.desertcart.com.cy/products/153827255-310mm-tr8x8-lead-screw-nema-17-integrated-linear-actuator-stepper) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-23*
