Lead screw

Lead Screw & Screw Shaft Manufacturer | Stainless Steel Trapezoidal & Ball Screws
Dream manufactures precision lead screws and screw shafts in stainless steel (304 / 316 / 316L) for linear motion, handwheel drives and transmission applications. OEM production, CAD/STEP/IGS, quick sampling.
Lead screws (trapezoidal / ACME) convert rotary motion to linear motion and are commonly paired with lead nuts for actuators, vises and manual handwheel assemblies. Screw shafts (keyed / splined / flanged) transmit torque and connect handwheels, gears or couplings in machines. We focus on stainless steel lead screws and screw shafts with precise thread profiles, consistent pitch, and durable surface treatments.
