Hicksville, NY – SDP/SI (ISO 9001 + AS9100D Registered) now carries all former Techno, Inc. stock of ACME lead screws and nuts. The lead screw selection is vast, with many different diameters, lengths, and number of starts available, as well as left-hand threads for certain sizes. The nuts come in several different materials and styles, including anti-backlash, ensuring that every linear motion application can be fitted with just right part. All SDP/SI Acme lead screws are made of high-quality 300 series stainless steel, and offer excellent corrosion resistance.

The main advantage of ACME lead screws over other styles is that the trapezoidal thread profile is much easier to manufacture, resulting in substantial cost savings. If the application doesn't call for the high efficiency offered by ball screws, ACME lead screws provide an appropriate, much cheaper alternative. Additionally, the larger thread contact area provides two distinct advantages. First, the load capacity is much higher. Second, the higher friction helps prevent back-driving. This makes them ideal for vertically raising and suspending heavy loads, like in car jacks and lifts.

SDP/SI offers a wide variety of inch and metric small mechanical components for the design engineer and OEM. Standard components can easily be located and purchased in one convenient place, shop online 24/7.
