T8 Lead Screw (Ø8 mm) with Nut Key benefits Converts rotary motion to precise linear motion for positioning and actuation. Three lead options (8 mm, 4 mm, 2 mm) let you choose speed or finer resolution: one full nut turn = 8 mm, 4 mm, or 2 mm respectively. Durable material pairing: 304 stainless steel screw rod for corrosion resistance and strength, matched with a copper nut for smooth bearing and wear resistance. Compact Ø8 mm diameter fits common stepper motor and small-actuator assemblies. What makes it useful T-type design: a modern lead-screw profile engineered for use in motion control applications. Interchangeable lead choices support a range of performance needs without changing the overall diameter or mounting footprint. Material combination balances longevity (stainless steel) with reduced friction and good conformity (copper nut). Technical highlights Model/profile: T8 (T-type screw) Diameter: 8 mm Lead options: 8 mm, 4 mm, 2 mm (one nut revolution = specified lead) Screw rod material: Stainless steel 304 Nut material: Copper Supplied with matching nut Suitable applications (examples) Stepping motor driven linear stages: couples to stepper motors for 3D printers, small CNC machines, or robotic joints where controlled linear motion is required. Machine tools and actuation: used in compact milling heads, fixtures, or adjustment screws for repeatable linear travel. Guide rails and automation: integrated into linear guides, slides, or pick-and-place systems for reliable translation between moving parts. Compatibility and selection tips Choose lead based on required trade-off between travel speed and positional resolution: 8 mm for faster travel, 2 mm for finer control. Ø8 mm T8 profile is commonly compatible with NEMA-style stepper motor couplings and compact linear assemblies; verify shaft coupling and end support dimensions for your setup. Material choice favors corrosion resistance and wear performance in general-purpose environments; confirm copper nut is acceptable for your load and lubrication requirements. Packaging and supply Supplied as a T8 screw rod (stainless steel 304) with matching copper nut. Available in the specified 8 mm diameter and three lead options (8 mm, 4 mm, 2 mm). This T8 lead screw provides a straightforward, material-appropriate solution for converting rotary motion into controlled linear motion in stepping motors, machine tools, guide rails, and related equipment.
