T12 Lead Screw 304 Stainless Steel with Brass Nut Corrosion‑Resistant Precision Linear Motion Rod 350mm

T12 Lead Screw with Brass Nut 304 Stainless Steel, Precision Thread, Key benefits Precision linear motion: Fine manufacturing and clear threads provide accurate linear travel with static and dynamic stiffness. Durable and corrosion resistant: Lead screw made from 304 stainless steel resists rust, offers wear resistance and temperature performance, and maintains reliable operation over time. Smooth operation and tight fit: Brass nut fits tightly for smooth sliding, reducing backlash and improving conversion efficiency. for DIY and upgrades: Select pitch, lead, and length options to fit a wide range of motion systems and custom projects. Specifications Model: T12 lead screw Thread diameter: 12 mm Available pitches: 2 mm, 3 mm Lead options: 2 mm, 3 mm, 4 mm, 8 mm, 10 mm, 12 mm, 14 mm, 20 mm Example length: 350 mm (lengths can be customized) Lead nut material: Brass Lead screw material: 304 stainless steel Performance and features Clear, precise threads for predictable, repeatable motion. stiffness and low wear for reliable positioning under load. Good thermal conductivity and temperature resistance for demanding environments. Tight nut engagement minimizes play and provides smooth, consistent sliding. Compatibility and applications Compatible with 3D printers for Z axis or custom linear assemblies. Suitable for stepper motor driven actuators and CNC machine tools. Ideal for engraving machines, DIY linear stages, and automated positioning systems. Typical use scenarios Upgrading a 3D printer Z axis: a worn lead screw to restore accurate layer height control and reduce wobble. Building a stepper motor linear actuator: Pair a T12 screw with a matching coupling and stepper motor to create a compact linear drive. Retrofitting a small CNC or engraving machine: Use the T12 screw and brass nut to improve stiffness and precision of table or carriage motion. Package includes 1 x T12 lead screw 1 x brass nut Notes Customized orders are accepted for pitch, lead, and length. Small measurement variations may occur due to different measuring tools; these do not affect function.
