Selecting Compatible Lead Screws and Nuts

Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won’t unexpectedly move when the lead screw is at rest. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.

Carbon steel lead screws and flanges have good machinability. Black-oxide alloy steel lead screws are hard and strong. They have mild corrosion resistance and a dark surface color. 303 and 304 stainless steel lead screws and flanges have good corrosion resistance.

932 bearing bronze and 673 bronze nuts are wear resistant. They have good machinability and fair corrosion resistance. Cast iron nuts have good machinability and high strength. 360 brass nuts have excellent machinability and good corrosion resistance. PET plastic nuts are lightweight and corrosion resistant. PEEK plastic nuts handle twice as much heat as PET and acetal plastic nuts. They have good chemical resistance and excellent corrosion resistance.

Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Lead Screws—Right-Hand-and-Left-Hand Threaded

Right-Hand-and-Left-Hand Threads

Right-hand-and-left-hand threaded lead screws have right-hand threads on one end and left-hand threads on the other. Use them where you want to drive nuts in opposite directions at the same time, such as for widening and narrowing chutes on packing and assembly lines. Note: A short length of threading at the center of the lead screw is not usable.

Flanges

Thread onto an externally threaded acme nut to create a custom flange nut.

Carbon steel flanges have good machinability. However, they will rust when exposed to moisture. Black-oxide carbon steel flanges have mild corrosion resistance in dry environments and a dark surface color. 303 stainless steel flanges have good corrosion resistance.
