Specification Brand : uxcell BulletPoint1 : Size&Packaging: The pitch of the linear motion lead screw is 2mm/0.08 inch and the lead is 8mm/0.32 inch, and the overall length is 350mm /13.78 inch. The nut model is Tr8X8, with a thickness of 15mm/0.59 inch and an outer diameter of 22mm/0.86 inches. The package includes one piece of the linear motion lead screw with four brass nuts and a PP plastic packaging tube BulletPoint2 : Material: Stainless steel lead screw and brass nut, with excellent anti-rust and corrosion performance. It is strong and durable, has a long service life, and is suitable for applications requiring durability and stability BulletPoint3 : Features: The lead screw is carefully designed to minimize friction between the nut and the screw, which enhances smoothness and precision in the operation of machines such as 3D printers and CNC machines. We will install the linear motion screw in the PP plastic packaging tube which is tough and light to protect it from pressure and moisture. At the same time, the plastic tube can also be used for protection and storage, and can also be used to place other things like oil paintings in it BulletPoint4 : Installation: To install the lead screw on a 3D printer or CNC machine, secure the mounting bracket to the base, insert the lead screw and make sure it rotates freely. Tighten the bracket, mount the nut that has four holes to the moving part with four screws, and finally and check if it works BulletPoint5 : Wide Usage: The lead screw is highly versatile, suitable for various applications. It is widely used in 3D printers for precision and reliability in prints. It also works well with stepper motors, improving automated system performance, and is perfect for CNC engraving machines, enabling intricate designs and detailed work ItemName : uxcell 2Pcs 350mm Lead Screw with Tr8x8 Brass Nut, Stainless Steel 3D Printer Upgrade Parts with Plastic Packaging Tube for 3D Printer Z Axis, CNC Machine, Silver ItemPackageDimensions_Height : 1.38 inches ItemPackageDimensions_Length : 14.76 inches ItemPackageDimensions_Width : 2.36 inches ItemTypeKeyword : linear-motion-lead-screws Manufacturer : uxcell PartNumber : a24102400ux0568 ProductDescription : Description: Material - Stainless steel lead screw and brass nut, with excellent anti-rust and corrosion performance.
