T16 Trapezoidal Lead Screw Set — precise, durable manual linear motion Key benefits Precise manual control: Robust handwheel provides smooth, accurate positioning for adjustments and fine tuning. Longlasting performance: Made from durable 45# steel for wear resistance and reliable operation over time. Flexible fit for projects: Available in multiple lengths (220mm, 250mm, 280mm, 300mm, 350mm) to match different travel needs without modification. Comfortable, spacesaving operation: Foldable aluminum alloy handwheel (100mm or 125mm) gives a secure grip for manual use and folds down to reduce clearance when not in use. What this product does for you Converts rotational input into stable linear motion for positioning, clamping, or actuation tasks. Reduces play and simplifies manual adjustments compared with loose or improvised mechanisms. Lets you select the correct screw length for clean installs and minimal trimming or rework.
