Stepper Motor with 18cm Lead Screw: 200 Steps-Rev, 42×38mmThis NEMA 17 size hybrid bipolar stepping motor has an integrated 18 cm (7) threaded rod as its output shaft, turning it into a linear actuator capable of precision open loop positioning. The included traveling nut has four mounting holes and moves 40 m (1. 6 mil) per full step; finer resolution can be achieved with microstepping.

This NEMA 17-size hybrid bipolar stepping motor has an integrated 18 cm (7″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).This linear positioning drive consists of our 42×38 mm NEMA17 stepper motor with a built-in lead screw in place of the normal output shaft, which makes it easy to move an object or platform in a linear motion with the precision of a stepper motor. Motors like this are especially popular for use in home-built 3D printers (e.g. RepRap) and CNC machines. The stainless steel threaded rod extends from the face of the stepper motor, and since it is integrated into the motor itself, you do not have to deal with bulky shaft couplers or loose set screws.
The included copper alloy traveling nut (also known as a carriage nut) features a mounting flange with four holes threaded for M3 screws. The nut moves 8.0 mm per full revolution of the lead screw, which allows for a linear resolution of 0.040 mm per full step of the stepper motor. Even smaller step sizes can be achieved through microstepping, which is a feature of many bipolar stepper motor drivers. We recommend the DRV8825 stepper motor driver carrier for use with this stepper motor, which allows for a linear resolution of 1.25 µm per 1/32 microstep. However, please note that the nut is not spring loaded, so changes in direction will result in loss of positioning precision due to backlash. Extra traveling nuts are also available for purchase separately.
The maximum achievable linear speed depends a lot on the details of the system, including the load and motor supply voltage. Under ideal conditions (e.g. with gradual ramping up of the step rate, a high supply voltage, and no load), we were able to achieve speeds close to 30 cm/s (12 in/s) with the 28 cm lead screw version.
The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in). The motor has four color-coded wires terminated with a JST XHP-4 connector with 0.1" spacing: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
Specifications

My son usually wears a Xl in men's clothing, suggests to go up 1 size to be safe
Size: XX-Large, Color: Navy With Blue, Size: XX-Large, Color: Navy With Blue
My son and I picked this suit out for his prom night coming up in May 2026. He trird it on and it fits, looks, and feels great on him!!! Color was spot on to what we wanted.. And how the picture looks is how it exactly came. He ordered a XXL, is 5'9" and weighs 235lbs

Awesome Suit!!
I purchased this suit for my boyfriend to wear to a party. I ordered an XL, he is 6'6" and 230lbs, initially the fit was fantastic and looks amazing but after wearing it and moving around in it for about 30 minutes, the pants started to slip down. The fabric has quite a bit of spandex in it and tends to stretch out after wearing for a little bit, it fits great right after it has been dried but then stretches out again. I ended up taking in the waist a little bit so the pants stay up, a large would likely have been a better fit. But he always looks amazing when he wears it and gets lots of compliments on the fun pattern. Definitely worth it!

Great suit!
Size: X-Large, Color: Navy With Blue
I was pleasantly surprised by the quality of this Mage Male dress suit. The material feels very soft with a velvet-like texture that makes the entire outfit pop without being over the top. This suit is perfect for prom, weddings, or any event where you want to elevate your look a bit.
Sizing was accurate for me, so make sure you follow the size chart closely. I recommend picking up an inexpensive tape measure here on Amazon to double-check your measurements — it makes a difference. For the price, this suit is absolutely worth it and I’d buy it again.

Looks great. Size ok.
Overall looks great. The fit was good other than the pants were a little too long and the adjustable bow tie strap was a little to short. I'm 5'9.5" and 170lbs with longer than average limbs for a comparison.
